In the embodiment of the present application, the execution subject of the flow is a server. The server includes but is not limited to: the cloud server, the computer and the like can execute the data interaction method provided by the application. Preferably, the server is a cloud server, which provides speech synthesis services. Fig. 1 shows a flowchart of an implementation of the method provided in the first embodiment of the present application, which is detailed as follows:
in S101, an attribute parameter of a connection pool is preconfigured, and the connection pool is established based on the attribute parameter.
In this embodiment, the attribute parameters include a minimum connection number and a maximum connection number; the connection pool is used for providing reusable websocket long connection; the websocket long connection is used for receiving interactive data fed back by the communication opposite end so as to carry out voice synthesis based on the interactive data. In the voice synthesis service, a communication opposite end can be provided with a client program related to a server, the communication opposite end can send a plurality of voice fragment data to the server for a plurality of times through the client, the server can carry out voice synthesis service on the received voice fragment data and feed back a synthesis result to the communication opposite end, namely, the data interaction process between the communication opposite end and the server is bidirectional, the communication opposite end can send data to the server through an uplink, and the server can also send data to the communication opposite end through a downlink, so that a websocket long connection needs to be established, and the communication opposite end and the server carry out data interaction through the established websocket long connection.
In this embodiment, for example, the attribute parameters of the connection pool are preconfigured according to the performance of the server, where the performance of the server includes memory resources, processor resources, and the like of the server. Specifically, the minimum connection number is set so as to keep the reusable websocket long connections with the same number as the minimum connection number in the connection pool for data interaction when a subsequent request for data interaction is responded for the first time; the maximum connection number is set to prevent the server from being insufficient or even down due to the excessive connection number. The reusable websocket long connection keeps a state to be activated in the connection pool, and the state to be activated specifically refers to: the websocket long connection is preset with the configuration information of the server, and when a communication channel is established before data interaction, the websocket long connection can be used only after the configuration information of the communication opposite terminal is configured, so that the configuration operation of parameters on the server side is reduced, resources occupied by the server for establishing the long connection are saved, and the speed of responding to a data interaction request is increased.
In S102, the total number of connections of the websocket long connection in the connection pool is monitored in real time.
In this embodiment, for example, by setting a system counter, the total number of connections of the websocket long connection in the connection pool is counted in real time, and specifically, each time the total number of connections changes, the count value of the portion of the system counter related to the total number of connections is adjusted accordingly, for example, when the total number of connections increases, the count value of the system counter is increased; and when the total number of the connections is reduced, reducing the count value of a system counter, and determining the total number of the connections of the websocket long connection in the connection pool in time through the system counter.
In S103, if a creation instruction about the websocket long connection is detected and the total number of connections is less than the maximum number of connections, a new websocket long connection is created in response to the creation instruction.
In this embodiment, when the server detects a creation instruction for the websocket long connection, that is, it means that the total number of the connections is to be increased by one, in order to ensure that the total number of the connections does not exceed the maximum number of the connections all the time, it is necessary to determine the number relationship between the total number of the connections and the maximum number of the connections before creating a new websocket long connection, and only if the total number of the connections is less than the maximum number of the connections, create a new websocket long connection so as to ensure that the total number of the connections does not exceed the maximum number of the connections all the time. It should be understood that if the total number of connections is greater than or equal to the maximum number of connections, no operation is performed to create a new long connection for the websocket.
Optionally, if the total number of the connections is greater than or equal to the maximum number of the connections, the server returns information of busy service to the correspondent node.
Optionally, if the total number of connections is greater than or equal to the maximum number of connections, after a preset waiting time elapses, the number relationship between the total number of connections and the maximum number of connections is determined again. If the total number of the connections is smaller than the maximum number of the connections, a new websocket long connection is created to ensure that the total number of the connections does not exceed the maximum number of the connections all the time; if the total number of the connections is still larger than or equal to the maximum number of the connections at this time, the server returns the information of busy service to the opposite communication terminal.
In S104, if a release instruction related to the websocket long connection is detected and the total number of connections is greater than the minimum number of connections, the websocket long connection corresponding to the release instruction is released to respond to the release instruction.
In this embodiment, when the server detects a release instruction about the websocket long connection, that is, it means that the total number of the connections is to be decreased by one, in order to ensure that the total number of the connections is always not less than the minimum number of the connections, it is necessary to determine the number relationship between the total number of the connections and the minimum number of the connections before releasing the websocket long connection, and only when the total number of the connections is greater than the minimum number of the connections, releasing the websocket long connection can ensure that the total number of the connections is always not less than the minimum number of the connections. It should be understood that if the total number of connections is less than or equal to the minimum number of connections, the operation of releasing the websocket long connection is not performed.
Optionally, the release instruction may be sent by the correspondent node to the server. The communication opposite end can actively require the server to release the websocket long connection for the data interaction between the communication opposite end and the server.
Optionally, when the server is restarted or the correspondent node sends a restart instruction to the server, and when the restart instruction is detected, a release instruction related to all websocket long connections in the connection pool is generated, so that the server does not perform the operation of judging the number relationship between the total number of the connections and the minimum number of the connections, directly releases all the long connections, and releases occupied server resources.
In this embodiment, if the total number of connections is too small, when responding to a plurality of data interaction requests, the connection pool may not have enough long connections to respond to the plurality of data interaction requests, so that a new long connection needs to be created, and creating the new long connection consumes resources of the server; if the total number of the connections is too large, the server needs to consume resources to maintain a large number of long connections, and even the server is down. Therefore, the minimum connection number and the maximum connection number need to be set, the total number of connections is maintained in the range from the minimum connection number to the maximum connection number by monitoring the total number of connections in real time and executing corresponding steps when the total number of connections changes, and balance between resource consumption when long connections in the connection pool and resource consumption when voice synthesis is performed is maintained, so that the server can respond to a data interaction request in time, simultaneously save consumed resources as much as possible, provide the server for voice synthesis service, and improve the performance of the whole voice synthesis service.
Fig. 2 shows a connection pool establishment flowchart of the method provided in the first embodiment of the present application, which is detailed as follows:
in S201, a plurality of long connections whose state identifiers are idle, which are in a number corresponding to the minimum connection number, are established in the connection pool, and the long connections whose state identifiers are idle are stored in an idle queue.
In this embodiment, the long connection with the state identifier of idle is the websocket long connection in the state to be activated. The idle queue is used for storing long connections with the state marks of being idle in the connection pool. Preferably, the free queue is a first-in-first-out queue. And before responding to the request of data interaction, pre-creating a plurality of long connections with idle state identifications corresponding to the minimum connection number, so that when the server subsequently responds to the request of data interaction initiated by the communication opposite terminal, the server can carry out data interaction with different communication opposite terminals by multiplexing the long connections with idle state identifications without creating new long connections.
In S202, a use queue is established in the connection pool for storing long connections whose status is identified as used.
In this embodiment, the long connection with the status flag being used is the websocket long connection in the use status.
In this embodiment, the long connection with the state identifier being idle is pre-created, so that when a data interaction request initiated by a communication peer is subsequently responded, the creation operation of the long connection is not required, thereby saving server resources and quickly realizing data interaction with the communication peer; preferably, the idle queue is a first-in first-out queue, so that when a request for data interaction needs to be responded, a long connection with the smallest queue number (i.e., a long connection with the longest time in a standby state) can be selected from the idle queue as a target long connection, the state identification of the target long connection is adjusted from idle to use, the target long connection is moved out of the idle queue, and the queue number of each long connection in the idle queue is adjusted again. The target long connection is removed from the idle queue and added to the use queue, and the long connection with the minimum queue number in the idle queue is selected, so that the selection and use probabilities of all the long connections in the idle queue are consistent, the use probability of each long connection with the state identification of idle in the connection pool is ensured to be equal, and the utilization rate of server resources is improved; the long connection of different state identifications in the connection pool is stored by establishing the two queues, so that the real-time monitoring on the long connection of different state identifications can be conveniently carried out subsequently.
Fig. 3 shows a flowchart of an implementation of the method provided in the second embodiment of the present application. Referring to fig. 3, in comparison with the embodiment shown in fig. 2, the method provided in this embodiment further includes steps S301 to S302, which are detailed as follows:
in S301, if a data interaction request instruction is received, determining whether the idle queue is empty; and if the idle queue in the connection pool is empty, generating a creation instruction about the websocket long connection.
In this embodiment, a data interaction request instruction, that is, a request required to respond to the data interaction, is received. Specifically, because a communication channel between the server and the communication peer needs to be established for data interaction, and a reusable long connection is created in the connection pool, the communication channel can be established by selecting the long connection from the idle queue in the connection pool, thereby implementing data interaction operation between the server and the communication peer. At this time, if it is detected that the free queue in the connection pool is empty, that is, no websocket long connection with a state identifier of being free is used for responding to the data interaction request instruction, a new websocket long connection needs to be created, so that a creation instruction about the websocket long connection needs to be generated, and thus, a creation operation of the websocket long connection is executed.
In S302, a new target long connection with the state identifier being idle is created through the creation instruction, and the target long connection is called to respond to the data interaction request instruction.
In this embodiment, if the server detects the creation instruction, a new target long connection with a new state identifier being idle is created according to the creation instruction, so as to respond to the data interaction request instruction, and a communication channel between the server and a communication peer is established through the target long connection, so as to perform data interaction operation.
It should be understood that, when the free queue is not empty, that is, the websocket long connection with the state identifier being free is used for responding to the data interaction request instruction, a websocket long connection with the state identifier being free is selected as a target long connection for responding to the data interaction request instruction (the specific selection manner may refer to a dequeuing manner of the queue, that is, the free websocket long connection corresponding to the head of the queue is selected as the target long connection), so as to respond to the data interaction request instruction, and establish a communication channel with a communication opposite end through the target long connection, so as to perform data interaction operation.
Further, S302 includes S3021 to S3022.
In S3021, the status identifier of the target long connection for responding to the data interaction request instruction is adjusted from idle to used, and the target long connection is added to the use queue of the connection pool.
In this embodiment, when the server invokes the target long connection for data interaction with the correspondent node, the target long connection may be converted from a state to be activated to a use state, at this time, the state identifier of the target long connection may be adjusted from idle to use, and the target long connection is removed from the idle queue and added to the use queue.
Preferably, when responding to the data interaction request instruction, determining whether the establishment of the communication channel using the target long connection is successful, illustratively, determining whether establishment success information sent by the communication peer is received; if the successful establishing information sent by the communication opposite end is not received within a preset time period, identifying that the target long connection fails to establish the communication channel, generating a new websocket long connection establishing instruction, establishing a new websocket long connection according to the new websocket long connection establishing instruction, replacing the target long connection to perform subsequent operation, and generating a release instruction related to the target long connection.
In S3022, a data interaction completion instruction is detected, the status identifier of the target long connection is adjusted from use to idle, and the target long connection is added to an idle queue in the connection pool.
In this embodiment, detecting a data interaction completion instruction means that the data interaction is completed, and therefore, it is necessary to adjust the state identifier of the target long connection from use to idle, and add the target long connection to an idle queue in the connection pool, so that when a data interaction request initiated by another communication peer is subsequently received, the long connection may be continuously invoked for responding.
Optionally, when responding to the data interaction request instruction, the target long connection is used to establish a communication channel, so that the communication peer and the server perform data interaction through the target long connection. In the voice synthesis service, the opposite communication terminal can send voice fragments to the server for multiple times through the built-in client terminal, and the server can also return data for voice synthesis according to the voice fragments to the opposite communication terminal for multiple times, wherein the opposite communication terminal can receive the data after voice synthesis through the built-in client terminal, and during the data interaction process, the opposite communication terminal or the server is required to stop the data interaction.
Preferably, when the server sends the last voice synthesized data to the correspondent node, the server makes the last voice synthesized data carry the data interaction completion identifier; and after the server finishes sending the last voice synthesized data, generating the data interaction finishing instruction.
Optionally, when the communication peer sends the last voice segment to the server, the last voice segment carries the data interaction completion identifier, and after the server performs voice synthesis according to the last voice segment and generates a synthesis result corresponding to the voice segment, the synthesis result may be returned to the client, and at this time, the server may generate the data interaction completion instruction.
In this embodiment, when a data interaction request instruction is responded, a target long connection with a state identifier being idle is selected from the idle queue for data interaction, so that setting of server configuration information is omitted, and resource consumption of a server for creating a new long connection is reduced; after the data interaction is completed, the state identification of the target long connection is only required to be adjusted from use to idle, and the target long connection is transferred from the use queue to the idle queue to respond to other data interaction requests without closing the target long connection, so that the resource consumption of a server for processing connection closing is saved.
Referring to fig. 4, fig. 4 shows an application scenario diagram of the method provided by an embodiment of the present application, which is detailed as follows: in an application scenario in the figure, a client of a communication peer needs a voice synthesis unit of a server to provide a voice synthesis service, and then a websocket long connection needs to be established for data interaction between the client and the voice synthesis unit of the server. The method comprises the steps that before a server provides voice synthesis service, attribute parameters of a connection pool are preconfigured, the connection pool is established, the connection pool creates websocket long connections with the same number as the minimum connection number in advance, and server configuration information is set in the websocket long connections in advance, so that only configuration information of a communication opposite terminal needs to be configured when a communication channel is established subsequently, and therefore resource consumption of the server is saved; after the preparation work of the server is completed, starting to receive a data interaction request instruction sent by the client, selecting a reusable websocket long connection in the connection pool, and establishing a communication channel between the client and a voice synthesis unit of the server so as to carry out data interaction subsequently; when data interaction is carried out, the client side sends a plurality of voice fragments to the voice synthesis unit of the server for a plurality of times, and the voice synthesis unit of the server returns voice synthesis data generated by voice synthesis of the voice fragments, so that voice synthesis service is completed.
Fig. 5 shows a flowchart of an implementation of the method provided in the third embodiment of the present application. Referring to fig. 5, in comparison with the embodiment shown in fig. 2, the method provided in this embodiment further includes S501, which is detailed as follows:
in S501, monitoring the idle duration of the long connection in which the status identifier is idle in the connection pool in real time;
in this embodiment, exemplarily, the system counter is used to time the idle duration of the long connection whose state identifier is idle in the connection pool in real time, specifically, each long connection whose state identifier is idle starts to be timed when being added into the idle queue, and the long connection whose state identifier is idle is ended when being removed from the idle queue, and the system counter is used to time the idle duration of the long connection whose state identifier is idle.
In S502, if the idle duration is greater than a preset standard duration, a release instruction for the long connection with the state identifier being idle is generated.
In this embodiment, the idle duration is a duration that the long connection whose state identifier is idle is continuously in the state to be activated. Illustratively, by setting a system timer, the idle duration of each long connection whose state identifier is idle in the connection pool is monitored in real time, and once it is monitored that the idle duration of a certain long connection whose state identifier is idle is greater than a preset standard duration, a release instruction of the long connection is generated.
It should be understood that if the idle duration of a long connection whose state identifier is idle is less than or equal to the preset standard duration, the operation of generating the release instruction of the long connection is not executed.
In this embodiment, since maintaining the long connection whose state identifier is idle in the connection pool also needs to consume server resources, in order to balance resource consumption when maintaining the long connection in the connection pool and resource consumption when performing speech synthesis, it is necessary to reduce resource consumption for maintaining the long connection whose state identifier is idle as little as possible on the premise of normally providing a speech synthesis service, and therefore, it is possible to release resources occupied by the long connection which is in a state to be activated for a long time by screening the long connection which is in a state to be activated for a long time. To achieve this, the present embodiment monitors the idle duration of the long connection whose status identifier is idle in the connection pool in real time; if the idle time length is longer than the preset standard time length, the long connection reaches the standard of needing to release the resource, and a release instruction of the long connection with the idle state identification can be generated to release the resource occupied by the long connection, so that the resource consumption of the server is saved.
Fig. 6 shows a flowchart of an implementation of the method provided in the fourth embodiment of the present application. Referring to fig. 6, in comparison with the embodiment shown in fig. 2, the method provided in this embodiment further includes step S601, which is detailed as follows:
in S601, the total number of connections of the websocket long connection in the connection pool is monitored in real time, and if the total number of connections is smaller than the minimum number of connections, a new long connection whose state identifier is idle is created until the total number of connections reaches the minimum number of connections.
In this embodiment, for example, the total number of connections of the websocket long connection in the connection pool is counted by the system counter set up above; and when the total number of the connections is monitored to be smaller than the minimum number of the connections, creating a new long connection with a state mark as idle until the total number of the connections reaches the minimum number of the connections. It should be understood that when the total number of connections is monitored to be greater than or equal to the minimum number of connections, the operation of creating a long connection whose new state identifier is idle is not performed.
In this embodiment, if the total number of connections is too small, when responding to a plurality of data interaction requests, the connection pool may not have enough long connections to respond to the plurality of data interaction requests, and thus a new long connection needs to be created, but creating a new long connection consumes resources of the server; moreover, in the above embodiment, there may be an operation of releasing multiple long connections, so to avoid a situation that the total number of connections is smaller than the minimum number of connections due to the operation of releasing multiple long connections, it is necessary to monitor the total number of connections of the websocket long connections in the connection pool in real time, and when the total number of connections is monitored to be smaller than the minimum number of connections, create a new long connection whose state identifier is idle until the total number of connections reaches the minimum number of connections, and ensure that the total number of connections is not smaller than the minimum number of connections.
It should be understood that the technical means of "monitoring the total number of connections of the websocket long connection in the connection pool in real time, and if the total number of connections is less than the minimum number of connections, creating a new long connection whose state identifier is idle until the total number of connections reaches the minimum number of connections" provided in this embodiment may replace the above technical means of "if a release instruction about the websocket long connection is detected and the total number of connections is greater than the minimum number of connections, releasing the websocket long connection corresponding to the release instruction, so as to respond to the release instruction", and both may only store one of the two or may coexist.
Fig. 7 shows a flowchart of an implementation of the method provided in the fifth embodiment of the present application. Referring to fig. 7, in comparison with the other embodiments, the method provided in this embodiment further includes step S701, which is specifically detailed as follows:
in S701, a first connection number of the idle queue and a second connection number of the used queue in the connection pool are monitored in real time.
In this embodiment, the system counter counts, in real time, a first connection number of an idle queue in the connection pool, where the first connection number is a connection number of a long connection whose state identifier stored in the idle queue is idle; and counting a second connection number of the use queue in the connection pool in real time through the system counter, wherein the second connection number is the connection number of the long connection used, and the state identifier stored in the use queue is the connection number of the long connection used.
In S702, monitoring information is generated according to the first connection number and the second connection number.
In this embodiment, the operation of generating the monitoring information according to the first connection number and the second connection number is performed once in a preset time interval, for example, the monitoring information includes a function graph of the first connection number and time and a function graph of the second connection number and time, and the monitoring information also includes monitoring information such as a real-time value, a maximum value, an average value, and a total value of the first connection number and the second connection number in the preset time interval.
In S703, the maximum connection number and/or the minimum connection number are adjusted based on the monitoring information.
In this embodiment, the monitoring information may include real-time values, maximum values, average values, total values, and the like of the first connection number and the second connection number in the preset time interval, and the maximum connection number and/or the minimum connection number may be adjusted according to the real-time values, the maximum values, the average values, and the total values.
It should be understood that the sum of the first connection number and the second connection number is the above-mentioned total number of connections, and the total number of connections is in the range of the minimum connection number to the maximum connection number. For example, in the preset time interval, if the average value of the first connection number is greater than the minimum connection number, adjusting the minimum connection number once to reduce the value of the minimum connection number, and/or adjusting the maximum connection number once to reduce the value of the maximum connection number; it should be understood that, if the average value of the first connection numbers is less than or equal to the minimum connection number, the operation of adjusting the maximum connection number and/or the minimum connection number is not performed.
Optionally, if the time duration of the time period in which the real-time value of the second connection number is greater than the minimum connection number occupies more than 50% of the preset time interval, adjusting the minimum connection number once to increase the value of the minimum connection number; it should be understood that if the time duration of the time period in which the real-time value of the second connection number is greater than the minimum connection number is within 50% of the preset time interval, the operation of adjusting the maximum connection number and/or the minimum connection number is not performed.
Optionally, if the maximum value of the second connection number is greater than 90% of the maximum connection number, and the average value of the second connection number is greater than 60% of the maximum connection number, the maximum connection number is adjusted once, so that the value of the maximum connection number is increased. It is to be understood that if the maximum value of the second connection number is less than or equal to 90% of the maximum connection number, or the average value of the second connection number is less than or equal to 60% of the maximum connection number, the operation of adjusting the maximum connection number and/or the minimum connection number is not performed.
Optionally, if the time duration with the first connection number being different from 0 occupies more than a preset percentage (for example, 60%) of the preset time interval, adjusting the standard time duration in the embodiment shown in fig. 5 to decrease the value of the standard time duration, where the decreased value is determined according to the percentage value of the time duration with the first connection number being different from 0 occupying the preset time interval; if the time duration in which the first connection number is not 0 occupies within a predetermined percentage (for example, 60%) of the predetermined time interval, the standard time duration in the embodiment shown in fig. 5 is adjusted to increase the value of the standard time duration, and the increased value is determined according to the percentage value of the time duration in which the first connection number is not 0 occupying the predetermined time interval.
In this embodiment, the minimum connection number and/or the maximum connection number are adjusted according to the monitoring information, so that the values of the minimum connection number and the maximum connection number are more reasonable, the resource consumption for maintaining the long connection in the connection pool is more reasonable, the resource consumption for maintaining the long connection in the connection pool and the resource consumption for performing speech synthesis are more balanced under the condition that the response data interaction request is satisfied, and the resources consumed by the server are saved as much as possible.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
