Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the related art, all subscriber information (subscribers) corresponding to a topic-pointer (topic-pointer) are acquired at one time based on the topic-pointer, and if the number of subscribers of a certain topic is too large, the data volume of the subscriber information acquired at one time is too large, and problems such as network congestion and machine performance tension are caused. To avoid the above problem, the number of subscribers to a single message topic (topic) is often limited.
Fig. 1 is a schematic diagram according to a first embodiment of the present disclosure, which provides an information acquisition method, including:
101. and receiving the message theme of the message to be routed sent by the client.
102. And if the number of all subscriber information corresponding to the message theme is larger than a preset value, acquiring part of the subscriber information in all the subscriber information.
103. And sending the part of subscriber information to the client.
As shown in fig. 2, the routing system may include: a client 201, a server 202 and a database 203.
The client may specifically refer to a routing client, and the server may specifically refer to a routing server.
The method of the embodiment can be applied to a server.
The client 201 may be located at a publisher side, so that, based on the routing system, the publisher may know the subscriber information, and then, based on the subscriber information, the publisher may send a message to a subscriber corresponding to the subscriber information.
The server 202 and the database 203 may be located on a server, and the server may be a local server or a cloud. The server 202 and the database 203 may be located on the same or different servers.
The server 202 receives a message topic (topic) sent by the client 201, and determines a topic-pointer corresponding to the received topic based on a correspondence between the message topic and a topic pointer (topic-pointer) established in advance. Generally, one topoc corresponds to only one topoc-pointer.
In the related art, the database 203 stores the correspondence between the topic-pointer and the subscriber information (subscriber), and the correspondence is generally stored in a Key-Value pair (KV) form, that is, K is the topic-pointer and V is the subscriber. One topoic-pointer may correspond to one or more (a plurality means at least two) subscribers. One subscriber includes one subscriber-id and one subscriber-meta-information (subscriber-metadata), and all subscriber information (subscribers) corresponding to one topic-pointer are acquired at one time.
The message topic is used to identify the message type, as shown in fig. 3, the message topic may be represented by a character string having a hierarchical relationship, the same subscriber may subscribe to different message topics, and different subscribers may subscribe to the same message topic.
In the related art, for example, referring to the upper part of fig. 3, 0x000D is a topic-pointer (topic-pointer), the inbox1(0) is subscriber information (subscriber), and the inbox1 is subscriber identifier (subscriber-id), where 0 represents corresponding subscriber meta-information (subscriber-metadata).
Assuming that the message topic is a message topic (× for/stock/nyse) in the first row, it may be determined that the topic pointer corresponding to the message topic is 0x000D, and the corresponding subscribers include inbox1(0) and inbox2(1), at this time, all subscriber information (subscribers) corresponding to 0x000D, that is, inbox1(0) and inbox2(1), are read at one time. If the number of the subscriber information is large, the problem of network congestion and the like can be caused, and in order to avoid the problem of network congestion and the like, the number of the subscriber information corresponding to each topic pointer is generally limited.
In order to expand the number of subscribers of the same message topic, in this embodiment, if the number of all subscriber information corresponding to the message topic is greater than a preset value, part of the subscriber information in all the subscriber information is acquired, and part of the subscribers is newly sent to the client.
That is, part of the subscriber information is acquired at a time, not all of the subscriber information, for example, 100 pieces of all subscriber information and 10 pieces of partial subscriber information at a time, so that all of the subscriber information can be acquired 10 times. Therefore, based on the batch-wise acquisition mode, all subscriber information can be acquired for multiple times, and the number of subscribers corresponding to each message topic is theoretically unlimited.
In the embodiment of the present disclosure, if the number of all subscriber information corresponding to the message topic is greater than a preset value, part of the subscriber information in all the subscriber information is acquired, and batch acquisition of all subscriber information of the same message topic can be realized, so that the number of subscribers of the same message topic is expanded.
In some embodiments, before acquiring part of subscriber information in all subscriber information if the number of all subscriber information corresponding to the message topic is greater than a preset value, the method further includes: receiving a specified number sent by the client, wherein the specified number is used for indicating the number of the partial subscriber information; correspondingly, if the number of all subscriber information corresponding to the message topic is greater than a preset value, acquiring part of the subscriber information in all the subscriber information, including: and if the number of all subscriber information corresponding to the message theme is greater than a preset value, acquiring part of subscriber information with the specified number.
That is, the number of partial subscriber information may be specified by the client, and the server sends the client-specified number of partial subscriber information to the client.
Because the client can also execute other operations, such as message sending and the like, if a large amount of subscriber information is obtained, the client may not be in time to process, so that data backlog is caused, and a large amount of memory space is occupied.
In some embodiments, the obtaining part of the total subscriber information includes: acquiring all theme pointers corresponding to the message theme; acquiring a to-be-processed theme pointer in all the theme pointers; based on the to-be-processed subject pointer, acquiring identification information, wherein the identification information comprises: the to-be-processed topic pointer and subscriber identifications of partial subscribers subscribing to the to-be-routed message; obtaining subscriber meta-information of the part of subscribers corresponding to the identification information; and acquiring the partial subscriber information based on the subscriber identification and the subscriber meta-information.
The to-be-processed subject pointer may be an entire subject pointer or a part of the entire subject pointers.
In the related art, the data corresponding to K is topic-pointer, and the data corresponding to V is subscriber-id + subscriber-metadata, so that all subscriber information corresponding to the topic-pointer is acquired at one time.
In order to obtain part of the subscriber information at a time, the present embodiment may modify KV.
As shown in the lower part of FIG. 3, in this embodiment, the data corresponding to K is topoic-pointer + subscriber-id, and the data corresponding to V is subscriber-metadata.
That is, in this embodiment, the identification information corresponding to each message topic is no longer a topic pointer, but is data composed of a topic pointer and a subscriber identification, or a topic pointer is used as a prefix.
For example, referring to fig. 3, it is assumed that the message topic is a message topic (× form/stock/nyse) in the first row, the topic pointer at this time is 0x000D, and after the descriptor-id is placed in the K part, the identification information corresponding to the message topic at this time includes: 0x000D + inbox1 (denoted by <0x000D > < inbox1> in fig. 3), and 0x000D + inbox2 (denoted by <0x000D > < inbox2> in fig. 3), i.e., the identification information includes a topic pointer and subscriber identification.
After the identification information is determined, the subscriber meta-information corresponding to the identification information may be obtained, for example, if the identification information is <0x000D > < inbox1>, the corresponding subscriber meta-information is 0.
The server obtains the subscriber meta-information by using the identification information (topic pointer + subscriber identification), for example, data of one KV line shown in fig. 3 (see the following embodiments, the specific line number obtained at each time may be specified) may be obtained each time, so as to implement batch obtaining of subscriber information corresponding to a certain message topic, for example, obtaining subscriber meta-information corresponding to <0x000D > < inbox1> for the first time, and obtaining subscriber meta-information corresponding to <0x000D > < inbox2> for the second time, instead of reading all at once, so that theoretically, each message topic may correspond to infinite subscriber information.
After obtaining the subscriber meta-information, the server may combine with the subscriber identity to obtain complete subscriber information, that is, the subscriber information is subscriber identity + subscriber meta-data, for example, the subscriber meta-information corresponding to the identity information <0x000D > < inbox1> is 0, and since the subscriber identity at this time is inbox1, the subscriber information may be obtained as inbox1(0) after combination.
By determining the identification information corresponding to the message topic, wherein the identification information comprises the topic pointer and the subscriber identification, and acquiring the subscriber meta-information based on the identification information, batch acquisition of the subscriber information of the same message topic can be realized, so that the number of subscribers of the same message topic is expanded.
In some embodiments, after the obtaining all topic pointers corresponding to the message topic and before the obtaining a to-be-processed topic pointer in all topic pointers, the method further includes: sending at least part of the subject pointers in the whole subject pointers to the client; correspondingly, the obtaining of the to-be-processed subject pointer in all the subject pointers includes: and receiving the to-be-processed subject pointer sent by the client, wherein the to-be-processed subject pointer is determined by the client in at least part of the subject pointers.
In some embodiments, after the at least part of the topic pointers are part of the topic pointers and all topic pointers corresponding to the message topics are obtained, the method further includes: and sending the subscriber information corresponding to other topic pointers to the client, wherein the other topic pointers are the topic pointers except for the part of the topic pointers in all the topic pointers.
In some embodiments, after receiving the message topic of the message to be routed sent by the client, the method further includes: and if the number of all subscriber information corresponding to the message topic is less than or equal to the preset value, all subscriber information is sent to the client.
That is, the server may send, to the client, at least part of the topic pointer and/or subscriber information corresponding to another part of the topic pointer except for the at least part of the topic pointer.
Although one topic corresponds to one topic-pointer, a topic subscribed by a subscriber may correspond to a plurality of topics, and thus, a plurality of topics-pointers may be obtained based on one topic. For example, referring to fig. 3, the topic subscribed by a certain subscriber is the topic of the second row (× form/stock/#), where "#" is a wildcard, and therefore, the subscriber at this time also subscribes to the topic of the first row (× form/stock/nyse), and thus, the topic-pointer corresponding to the topic of the first row and the topic-pointer corresponding to the topic of the second row can be obtained based on the topic of the second row.
Taking the second line topic as an example, all the subject pointers at this time are topic-pointers corresponding to the topic of the first line and topic-pointers corresponding to the topic of the second line. At this time, both the subject pointers may be sent to the client; or, the subscriber information corresponding to some of the topic pointers and other some topic pointers may be sent to the client, for example, the topic-pointer corresponding to the topic of the first line and the subscriber information (inbox2(0)) corresponding to the topic of the first line may be sent to the client.
Assuming that the server sends a plurality of topic pointers (topic-pointers) of a certain topic to the client, the client may designate a to-be-processed topic pointer in the plurality of topic pointers, for example, select all or part of the received topic pointers as the to-be-processed topic pointers, and send the to-be-processed topic pointers to the server.
The client specifies the to-be-processed topic pointer, so that the subscriber information can be acquired in batches based on the client requirements.
When the server returns the topic pointer to the client, the server also returns the subscriber information, so that the client can prefetch at least part of the subscriber information, and the acquisition efficiency of the subscriber information is improved.
When the number of all subscriber information is small, all subscriber information is acquired at one time, so that a secondary request of a client to a server can be avoided, and resources are saved.
Fig. 4 is a schematic diagram according to a fourth embodiment of the present disclosure, where this embodiment provides an information obtaining method, and the method is implemented by a client as an example, and includes:
401. and sending a message theme of the message to be routed to a server, wherein the message theme is used for triggering the server to respond that the number of all subscriber information corresponding to the message theme is greater than a preset value, and acquiring part of the subscriber information in all the subscriber information based on the message theme.
402. And receiving the part of subscriber information sent by the server.
In some embodiments, before the receiving the partial subscriber information sent by the server, the method further includes:
and sending a specified number to the server, wherein the specified number is used for triggering the server to acquire the part of subscriber information of which the number is the specified number.
In some embodiments, after the sending the message topic of the message to be routed to the server and before the receiving the part of the subscriber information sent by the server, the method further includes:
receiving at least part of the subject pointers in all the subject pointers corresponding to the message subjects sent by the server;
determining a to-be-processed subject pointer in the at least part of the subject pointers;
sending the to-be-processed subject pointer to the server, where the to-be-processed subject pointer is used to trigger the server to obtain identification information based on the to-be-processed subject pointer, obtain subscriber meta-information based on the identification information, and obtain the partial subscriber information based on the identification information and the subscriber meta-information, where the identification information includes: the pointer to the topic to be processed, and subscriber identification of part of subscribers subscribing the message to be routed.
In some embodiments, the at least part of the topic pointer is a part of the topic pointer, and after the message topic of the message to be routed is sent to the server, the method further includes:
and receiving subscriber information corresponding to other topic pointers sent by the server, wherein the other topic pointers are topic pointers except for the part of topic pointers in all the topic pointers.
In some embodiments, after sending the message topic of the message to be routed to the server, the method further includes:
and receiving all the subscriber information sent by the server end in response to the fact that the number of all the subscriber information corresponding to the message topic is smaller than or equal to a preset value.
The process executed by the client corresponds to the process executed by the server, and specific contents and effects thereof may refer to the relevant description of the embodiment corresponding to the server.
In the embodiment of the disclosure, all subscriber information of the same message topic can be obtained in batches by receiving part of the subscriber information sent by the server, so that the number of subscribers of the same message topic is expanded.
Fig. 5 is a schematic diagram according to a fifth embodiment of the present disclosure, in this embodiment, an information obtaining method is provided, and in this embodiment, taking interaction between a client and a server as an example, the method of this embodiment includes:
501. and the client sends the message theme of the message to be routed to the server.
502. And the server side determines a subject pointer corresponding to the message subject based on the corresponding relation between the message subject and the subject pointer established in advance. And the server side sends the subject pointer and/or the prefetched subscriber information to the client side.
For example, the message topic in the second line of fig. 3 corresponds to the message topic in the first line and the message topic in the second line, so that one or more topic pointers can be obtained based on one message topic.
The process of 501-502 may be referred to as a topic matching (matchtopic) process.
In the related technology, the client side can send the message theme to the server side, the server side converts the message theme into a theme pointer, all subscriber information is searched based on the theme pointer, and all subscriber information is returned to the client side once again. In general, there is a network request between the client and the server.
In this embodiment, in order to implement batch acquisition of subscriber information, at this time, network requests may be divided into two times, where the first request may obtain a topic pointer, and the second request obtains subscriber information based on the topic pointer.
That is, after the server obtains the topic pointer based on the message topic, the topic pointer can be returned to the client. Alternatively, the first and second liquid crystal display panels may be,
after the server side obtains the topic pointer, if the number of all subscriber information corresponding to the topic pointer is small, all subscriber information can be directly returned to the client side at the moment without feedback of the topic pointer, that is, all subscriber information can be returned through one network request, so that one network request can be saved and the performance can be improved when the number of all subscriber information is small.
It is understood that it is also possible to return a portion of the topic pointer, and the subscriber information corresponding to the additional portion of the topic pointer.
The subscriber information returned by the server based on the first request (message topic) sent by the client may be referred to as prefetched subscriber information.
503. And the client sends the theme pointer to the server.
The process that the client acquires the subscriber information based on the topic pointer can be realized through fetchsubscribe service. Specifically, after the client receives the theme pointer sent by the server, the theme pointer may be used as a parameter to call the fetchSubscriber service, the fetchSubscriber service may be located at the client, and the fetchSubscriber service may send the theme pointer selected by the client to the server. The topic pointers sent by the client to the server can be one or more, and when the topic pointers are multiple, the topic pointers can be sent to the server together in a list form.
504. The client sends the specified number to the server.
The client may send the specified number (requestsize) one or more times, for example, a first specified number is sent for the first time, a second specified number is sent for the second time, and the specified numbers at each time may be the same or different.
The server side determines the theme pointer and sends the theme pointer to the client side, and the client side sends the theme pointer to the server side when obtaining the subscriber information. After the server determines the topic pointers, the topic pointers are not returned to the client, but when the client needs to acquire the subscriber information, the server sends the specified number to the server, and the server acquires the corresponding subscriber information according to the specified number and the previously determined topic pointers.
505. The server side sends the specified quantity to the database.
The database of this embodiment may be referred to as rearranged kv (orderdk), where K corresponds to topoic-pointer + subscriber-id, and V corresponds to subscriber-metadata.
506. And the database returns the KV to the server.
In order to ensure the accuracy of the data searched by the database, current identification information, which may also be referred to as a cursor (cursor), may be recorded each time KV is obtained based on a specified number, so that the search may be continued from the position of the current identification information next time.
For example, K in the database corresponds to identification information, the identification information includes topoic-pointer + subscriber-ID, and it is assumed that the identification information is represented by ID1, ID2, ID3, and the like, and it is assumed that the current specified number is 2, that is, the database can find data corresponding to ID1 and ID2, at this time, it may record that the current identification information is ID2, and continue to find from ID2 next time, that is, the first number of data corresponding to ID3 next time.
The data searched by the database and returned to the server may be referred to as KV, that is, include K and V, where K is a topic pointer and a subscriber identifier (topic-pointer + subscriber-id), and V is subscriber meta information (subscriber-metadata).
For a scene with a plurality of subject pointers, the total data volume of the plurality of subject pointers can be guaranteed to be a specified number, and the data volume of each subject pointer is not limited. For example, if the specified number is 10, the data size corresponding to the first topic pointer may be 2, and the data size corresponding to the second topic pointer may be 8; alternatively, the data size corresponding to the first subject pointer may be 5, and the data size corresponding to the second subject pointer may be 5.
507. And the server side sends the subscriber information to the client side.
After the server obtains the KV, the server may combine the subscriber identifier in K and the subscriber meta-information in V to obtain complete subscriber information, that is, subscriber-id + subscriber-meta-information, and then return the subscriber-id + subscriber-meta-information to the client.
In this embodiment, the subscripter is split, the subscripter-id is put into a key as a suffix, and the subscripter-meta is used as a value, that is, < topic-pointer + subscripter-id, and subscripter-metadata > are stored as a pair of KV, and the topic-pointer can be used as a prefix for batch reading during matching, so that a single topic can be subscribed by a large number of subscripters (theoretically, the number is not limited), and the situation of resource shortage such as network congestion is not caused.
It is understood that the details, which are not described in detail in one embodiment of the present disclosure, may be referred to in the description of other embodiments.
It is to be understood that the timing relationship between the steps in the embodiments is not limited, unless a timing relationship is necessarily required.
