Description
Technical Field
The embodiment of the invention relates to the technical field of data processing, in particular to an identifier generation method, an identifier generation device, a storage medium and a system.
Background
In today's big data age, large amounts of data and messages are generated every day. To better distinguish between different data and messages, unique identification of the data and messages is often required. Among the most common identification methods is to add a unique identifier to data and messages. While the identifier may be a primary element of the information system analyzing user behavior, locating system faults, and accounting for system performance.
In the related art, a number segment mode is adopted by a number sender component to generate a globally unique identifier, so that the uniqueness of the identifier in a distributed system architecture is ensured. Specifically, each service instance first gets the identifier from the system in bulk and caches it locally. When the service application requests to acquire the identifier, the identifier is locally added back until the number segment is exhausted and then the next number segment is acquired again in the system.
However, this solution has significant limitations. If the client side is abnormal suddenly but the number segments are not used up, the client side can access the system again to obtain new number segments when being restarted, and therefore a great deal of waste of number segment resources is caused. In addition, the scheme is to synchronously acquire the next number segment after the number segment is used up, and if the network shakes or the system slowly inquires, the response time of the whole system is slowed down.

Fig. 1 is a flowchart of an identifier generation method provided by an embodiment of the present invention, and the embodiment of the present invention is applicable to a case where a dual-cache number is used to obtain a target identifier, and the method is applied to an identifier generation system, where the identifier generation system includes a first number cache region and a second number cache region, and the method may be executed by an identifier generation apparatus, which may be composed of hardware and/or software, and may be generally integrated in the identifier generation system. As shown in fig. 1, the method specifically includes the following steps:
The identifier may refer to an identification symbol of the data or the message, and may be used to uniquely identify the data or the message. Illustratively, the identifier may be an ID number. The identifier acquisition event may refer to a task event for instructing acquisition of an identifier. When the system detects an instruction for identifier retrieval, an identifier retrieval event may be triggered, instructing the system to retrieve the identifier from the database. The identifier configuration parameter may refer to a parameter for configuring the identifier, for example, the identifier configuration parameter may include a modulus value, a remainder, and the like. The number segment may refer to a block segment containing multiple identifiers. For example, if the identifier is set as an ID number, 1-1000 in the ID number can be used as one number segment, and 1001-2000 can be used as another number segment. The number segment cache region may refer to a region in the system for pre-storing the number segment. The first number segment cache region and the second number segment cache region are only used for explaining two different number segment cache regions in the system, and the sequence is not distinguished. The current number segment cache region can be understood as a cache region where the current number segment is located, wherein the current number segment cache region is a first number segment cache region or a second number segment cache region.
In the embodiment of the present invention, when the identifier obtaining event is triggered, the target identifier may be obtained from the number segment stored in the current number segment cache region in different manners according to the identifier configuration parameter. Specifically, the target identifier may be directly obtained in an incremental manner, or may be obtained by configuring a modulus value and a remainder. Illustratively, if the current number segment is 1-10000, i.e. the starting value is 1 and the maximum value is 10000, when the modulus value is 2 and the remainder is 0, the obtained target identifiers are 2, 4, 6,. multidrug, 9998, 10000 respectively; when the modulus value is 2 and the remainder is 1, the obtained target identifiers are 1, 3, 5,. ang., 9997, 9999, respectively.
In embodiments of the present invention, conversion between identifiers of different formats may be supported. For example, numeric value to designated binary string can be supported, and string to designated binary numeric value can also be supported. Specifically, conversion between a positive integer value and a character string within a 2-62 system can be realized according to actual requirements. For example, if the obtained identifier is an integer value 1234567890, after the obtained identifier is converted into 36-ary, the character string may be KF12OI, and the original 10-bit value is converted into a 6-bit character string.
The advantage of this arrangement is that identifiers in multiple formats can be supported by simple data compression and encoding mechanisms, and information security can be improved, thereby effectively avoiding information leakage and crawling.
The preset threshold may be a low-level value in a preset number segment, and may be used to indicate that the number segment stored in the current number segment cache region is about to be used up. Specifically, the preset threshold may be set to a certain fixed value in the number segment stored in the current number segment cache region, and the preset threshold is fixed at this time, or may be set according to a percentage, and at this time, the preset threshold may change according to the number segment stored in the current number segment cache region. For example, the preset threshold may be set to 90% of the maximum number of segments stored in the current number of segments buffer. Assuming that the current number segment is 1-1000, the preset threshold is 1000 × 90% — 900; assuming the current number segment is 1-900, the preset threshold is 900 × 90% — 810.
In the embodiment of the present invention, the another number of segment cache regions may refer to the number of segment cache regions except the current number of segment cache region in the first number of segment cache regions and the second number of segment cache regions. It should be noted that, the current number of cache blocks and the other number of cache blocks are relative, and only two cache blocks in the system are involved, and the current number of cache blocks and the other number of cache blocks are not fixed but alternate according to the location of the current number of cache blocks. Fig. 2 is a diagram illustrating a number cache according to an embodiment of the present invention. The buffer comprises two buffer areas, namely, a buffer area A and a buffer area B, wherein the number of the buffer area A is 1-1000, and the number of the buffer area B is 1001-2000. Specifically, if the current number segment is located in a, a is the current number segment cache region, and at this time B is another number segment cache region; if the current number segment is located in B, B is the current number segment buffer area, and A is another number segment buffer area at the moment. Therefore, both A and B can be used as the current number segment buffer or another number segment buffer, and one of them is used as the current number segment buffer and the other is used as the other number segment buffer.
In the embodiment of the present invention, the obtained target identifier may be respectively compared with a preset threshold in the number segment stored in the current number segment cache region, and when the target identifier is greater than the preset threshold, it indicates that the number segment stored in the current number segment cache region is about to be used up, at this time, the target number segment is determined, and the target number segment is stored in another number segment cache region. For example, assuming that the current number of segments is 1-1000 and the preset threshold is 900, when the acquired target identifier is greater than 900, the target number of segments is determined and stored in another segment buffer. It should be noted that the number segments stored in the target number segment buffer and the number segments stored in the current number segment buffer may be continuous or discontinuous, and the length of the target number segment and the length of the number segments stored in the current number segment buffer may be the same or different, and is not limited herein.
In the embodiment of the present invention, when the last identifier that can be obtained is obtained from the number segment stored in the current number segment cache, it may be considered that the identifiers in the number segment stored in the current number segment cache are used up. It should be noted that the identifier is used up and does not represent that the identifier can not obtain the end position of the number segment stored in the current number segment cache, that is, the last identifier that can be obtained is not necessarily the identifier of the end position of the number segment stored in the current number segment cache, and may also be an identifier at another position before the end position. For example, assuming that the current number segment is 1-10000, and the obtained identifiers are 1, 3, 5., 9997, 9999, respectively, the termination value 10000 cannot be obtained, so that when 9999 is obtained, it may indicate that the identifiers in the number segments stored in the current number segment cache are used up.
In the embodiment of the present invention, when the target identifier is greater than the preset threshold in the number segment stored in the current number segment cache region, if the target number segment is not updated, the target number segment may be updated by using the asynchronous thread in the asynchronous thread pool. If the identifiers in the number segments stored in the current number segment cache are used up, namely after the current number segments are all issued, the other number segment cache region can be used as the current number segment cache region, namely the current number segments are switched to the target number segments, and the identifiers are issued in a circulating and reciprocating manner.
The embodiment of the invention provides an identifier generation method, which comprises the steps of responding to an identifier acquisition event to be triggered, and acquiring a target identifier from a number segment stored in a current number segment cache region based on an identifier configuration parameter; the current number section cache region is a first number section cache region or a second number section cache region; when the target identifier is larger than a preset threshold value in the number segment stored in the current number segment cache region, determining a target number segment and storing the target number segment in another number segment cache region; wherein, the other number segment cache region is the number segment cache region except the current number segment cache region in the first number segment cache region and the second number segment cache region; and when the identifiers in the number segments stored in the current number segment cache are used up, taking the other number segment cache region as the current number segment cache region, and returning to execute the acquisition of the target identifiers from the number segments stored in the current number segment cache region based on the identifier configuration parameters. According to the technical scheme provided by the embodiment of the invention, the identifiers can be acquired from the database of the system through the double-cache number sections without blocking, so that the problem of requesting thread blocking when the number sections are acquired from the database and the number sections are updated is effectively avoided, the timeliness of acquiring the identifiers is effectively ensured, and the problems of machine downtime and resource waste caused by the surge of traffic can be effectively avoided.
In some embodiments, when the target identifier is greater than a preset threshold in the number segments stored in the current number segment cache, determining the target number segment includes: when the target identifier is larger than a preset threshold value in the number segment stored in the current number segment cache region, determining a target number segment according to the number segment stored in the current number segment cache region; and the difference value between the initial value of the target number segment and the termination value of the number segment stored in the current number segment cache region is 1.
Wherein, the start value and the end value can be identifiers corresponding to the start position and the end position in the number segment, respectively. In the embodiment of the present invention, when the target identifier is greater than the preset threshold in the number segment stored in the current number segment cache region, the target number segment may be determined according to the number segment stored in the current number segment cache region. The difference between the start value of the target number segment and the end value of the number segment stored in the current number segment cache region is 1, that is, the sum of the end value of the number segment stored in the current number segment cache region and 1 is the start value of the target number segment. It is understood that the difference between the start value of the target number segment and the end value of the number segment stored in the current number segment buffer is 1, indicating that the target number segment is consecutive to the number segment stored in the current number segment buffer. For example, assume that the number stored in the current number buffer is 1-1000, that is, the initial value of the number stored in the current number buffer is 1 and the end value is 1000, and the initial value of the target number is 1000+1 — 1001.
The method has the advantages that the target number segment and the number segment stored in the current number segment cache region can be ensured to be continuous, and resource waste of the identifier in the number segment is avoided.
Optionally, determining a target number segment according to the number segment stored in the current number segment cache region includes: determining the step length and the termination value of the number segment stored in the current number segment cache region; and determining the target number segment according to the step length and the termination value of the number segment stored in the current number segment cache region.
In the embodiment of the present invention, when the number segment stored in the current number segment buffer is known, the start value, the step size, and the end value of the number segment can be determined. The step size may be expressed as a difference between the end value and the start value, i.e., the step size is the end value — the start value. Then adding 1 to the ending value of the number segment stored in the current number segment cache region to obtain the starting value of the target number segment. And then the target number segment can be determined according to the initial value and the step length of the target number segment. It should be noted that the step size of the target number segment may be greater than, less than, or equal to the step size of the number segment stored in the current number segment buffer, that is, the two may be the same or different.
Optionally, determining the target number segment according to the step length and the end value of the number segment stored in the current number segment cache region includes: calculating the step length of the target number segment according to the step length of the number segment stored in the current number segment cache region and a preset adjustment factor; determining the termination value of the target number segment according to the termination value of the number segment stored in the current number segment cache region and the step length of the target number segment; and the ending value of the target number segment is the sum of the ending value of the number segment stored in the current number segment cache region, the step length of the target number segment and 1.
The preset adjustment factor may refer to a preset value for adjusting the step length. In the embodiment of the invention, the step length of the target number segment can be calculated according to the step length of the number segment stored in the current number segment cache region and the preset adjustment factor. For example, the step size of the target number segment may be obtained by taking the product of the step size of the number segment stored in the current number segment buffer and the preset adjustment factor, or the ratio of the step size of the number segment stored in the current number segment buffer and the preset adjustment factor, which is not limited herein.
In the embodiment of the invention, the termination value of the target number segment can be obtained by calculation according to the termination value of the number segment stored in the current number segment cache region and the step length of the target number segment. Specifically, the end value of the target number segment may be represented as the sum of the end value of the number segment stored in the current number segment buffer, the step size of the target number segment, and 1, that is, the end value of the target number segment is equal to the end value of the number segment stored in the current number segment buffer + the step size of the target number segment + 1. Wherein, the ending value +1 of the number segment stored in the current number segment cache region is the starting value of the target number segment.
The advantage of setting up like this is on the basis of guaranteeing the number section is continuous, can carry out the flexibility adjustment to the step length of target number section according to actual demand through presetting adjustment factor to the flexibility and the adaptability of target number section have been strengthened.
Optionally, the preset adjustment factor is greater than 1; before calculating the step length of the target number segment according to the step length of the number segment stored in the current number segment cache region and a preset adjustment factor, the method further comprises the following steps: determining the updating period of the number segments stored in the current number segment cache region; wherein, the updating period is the difference value between the asynchronous updating number segment time and the time for starting to use the number segment stored in the current number segment cache region; the asynchronous number segment updating time is the time when the target identifier begins to be larger than a preset threshold value in the number segment stored in the current number segment cache region; correspondingly, calculating the step length of the target number segment according to the step length of the number segment stored in the current number segment cache region and a preset adjustment factor, wherein the step length of the target number segment includes: when the updating period is smaller than a first time threshold, calculating the product of the step length of the number segment stored in the current number segment cache region and the preset adjusting factor, and determining the product as the step length of the target number segment; when the updating period is larger than the first time threshold and smaller than a second time threshold, taking the step length of the number segment stored in the current number segment cache region as the step length of the target number segment; and when the updating period is greater than the second time threshold, calculating the ratio of the step length of the number segment stored in the current number segment cache region to the preset adjusting factor, and determining the ratio as the step length of the target number segment.
The update period may refer to a time period for updating the number segment. Specifically, the update period may be expressed as a difference between the asynchronous update number segment time and the time when the use of the number segment stored in the current number segment buffer begins. The asynchronous number segment updating time may be a time when the target identifier starts to be greater than a preset threshold in the number segment stored in the current number segment cache region, which is equivalent to a time when the first occurrence of the target identifier is greater than the preset threshold in the number segment stored in the current number segment cache region. For example, it is assumed that when the number of preceding segments is 1-1000, the preset threshold is 900, and the obtained target identifiers are 1, 3, 5, 7, …, 997, 999 respectively, the update period is the time difference between the obtained target identifier being 901 and the obtained target identifier being 1.
In the embodiment of the present invention, the preset adjustment factor is greater than 1. After determining the update period of the number segment stored in the current number segment cache region, the update period may be compared with a preset time threshold, and the step length of the target number segment is adjusted by using the step length of the number segment stored in the current number segment cache region and a preset adjustment factor according to the comparison result. The time threshold may include a first time threshold and a second time threshold, and the first time threshold is smaller than the second time threshold. Specifically, when the update period is less than the first time threshold, it indicates that the current traffic volume is increased sharply, so that the demand for obtaining the identifier is increased, and at this time, the product of the step size of the number segment stored in the current number segment cache region and the preset adjustment factor can be used as the step size of the target number segment, so as to increase the step size of the target number segment, so as to meet the requirement of larger traffic volume; when the update period is greater than the first time threshold and less than the second time threshold, the required quantity of the currently acquired identifier is in a normal range, and the step length of the number segment stored in the current number segment cache area can be directly used as the step length of the target number segment; when the update period is greater than the second time threshold, it indicates that the demand for obtaining the identifier currently is in a lower range, and at this time, the ratio of the step size of the number segment stored in the current number segment cache region to the preset adjustment factor may be used as the step size of the target number segment, so as to reduce the step size of the target number segment, and avoid the waste of number segment resources.
For example, it is assumed that in the number segment stored in the current number segment buffer, the initial value and the step size are 0 and 3000, respectively, the preset adjustment factor is 3, the preset threshold is 30% of the termination value, and the first time threshold and the second time threshold are 5 minutes and 10 minutes, respectively. When the throughput of a single server in the system is 1.5-3TPS, the step length of the target number segment does not need to be adjusted. When the throughput of the single server is increased to 50TPS, when the asynchronous segment update is triggered for the first time, the step size of the target segment can be changed to 3 × 3000, that is, 9000, at which time the target segment is changed to 3000-. When the single server throughput is reduced to 2TPS, the loop iteration is again reduced from a step size of 54000 to 3000. Preferably, the step size of the target number segment may be set to 600 times of the throughput of the system server in the peak period of the service. Where throughput may refer to the number of identifiers that need to be acquired. In this case, even if the system server goes down, the system server can continuously send the number for 10-20 minutes through the number sender without being influenced. In addition, the time threshold and the preset threshold in the present invention may also refer to this configuration.
The method has the advantages that the step length of the target number segment can be adaptively and iteratively adjusted through the preset adjusting factor, the preset threshold value, the number segment updating period and the time threshold value according to the current service throughput, so that the current service requirement can be better adapted.
In some embodiments, before the acquiring the target identifier from the number segment stored in the current number segment cache area based on the identifier configuration parameter in response to the identifier acquisition event being triggered, the method further comprises: and reading an initial number segment from any number segment database in the number segment database set, and storing the initial number segment in the current number segment cache region.
The number segment database may refer to a database for generating and storing number segments. A database set may refer to a set consisting of a plurality of databases, that is, a database set includes at least two databases. The initial number segment may refer to the number segment that is read from the number segment database for the first time. In an embodiment of the invention, a plurality of number segment databases may be provided for use by the server. The different number segment databases can autonomously configure the identifier configuration parameters, and do not interfere with each other. For example, the same number segment and different module values and remainders may be configured, and different number segments and the same module values and remainders may be configured. Assuming that there are two number segment databases, the number segment database 1 configures the number segment with a starting value of 1, a maximum value of 10000, a modulus value of 2, and a remainder of 0, and the generated identifier is 2, 4, 6. The number segment database 2 configures the number segment to have a start value of 1, a maximum value of 10000, a modulus value of 2, and a remainder of 1, and then generates identifiers of 1, 3, 5. After reading the initial number segment from any one of the number segment databases in the number segment database set, the initial number segment may be stored in the current number segment cache region.
The method has the advantages that the database with a plurality of number segments can be provided for the server to use, so that a database multi-master mode is realized, and the usability problem caused by the breakdown of a single database and the hot bank problem caused by frequent access to the single database can be effectively avoided.
Fig. 3 is a flowchart of an identifier generation method according to another embodiment of the present invention. The method is applied to an identifier generation system, wherein the identifier generation system comprises a first number segment cache region and a second number segment cache region. As shown in fig. 3, the method specifically includes the following steps:
Wherein the traffic type may be used to distinguish between different traffic. In the embodiment of the invention, the table creation and data bottom laying work of the number segment can be made in the number segment database according to the data type, and the step length of the number segment can be divided according to the service type. The data types may include Oracle, Mysql, and the like. It should be noted that the initial creation of the generator can be completed when the number segment number sender is accessed for the first time, and the subsequent access again can be directly used without creating again. In addition, two number segment buffer areas are arranged in the number segment sender of any service type. When it is detected that an identifier acquisition event is triggered, a service type matching the identifier acquisition event may be acquired.
In the embodiment of the present invention, the service type and the identifier configuration parameter have a corresponding relationship, and the corresponding relationship between the service type and the identifier configuration parameter may be stored in the system in advance. When the service type matched with the identifier acquisition event is acquired, the identifier configuration parameter corresponding to the service type can be acquired according to the pre-stored corresponding relationship between the service type and the identifier configuration parameter.
The specific implementation manner of steps 330-350 can be seen in the detailed description of steps 110-130.
The embodiment of the invention provides an identifier generation method, which can not only acquire identifiers from a system database through double cache number sections without blocking and effectively avoid the problem of requesting thread blocking when the number sections are acquired from the database and the number sections are updated, thereby effectively ensuring the timeliness of the acquisition of the identifiers, but also effectively avoiding the problems of machine downtime and resource waste caused by surge of traffic and acquiring corresponding identifiers according to the types of the traffic.
Fig. 4 is a flowchart of a preferred identifier generation method according to another embodiment of the present invention. The method can monitor the consumption speed of the identifier in real time aiming at the number segment senders with different service types through the management interface. The initial value, the step length, the preset threshold value and the time threshold value of the identifier in the number segment database can be modified through the management interface, and the number segment can be obtained again through the number obtaining device after the modification is completed.
Fig. 5 is a schematic structural diagram of an identifier generation system according to another embodiment of the present invention. The identifier generation system comprises a number segment sender table configuration module, a number segment sender service module and a number segment sender number taking module. The number segment sender table configuration module can be used for configuring corresponding number segments in the number segment database according to the service types, and the number segment of different service types is prevented from being duplicated. The number segment sender service module can be used for loading the service type and the number segment configured in the table into the cache service, and can convert the format of the identifier and shorten the length according to the service requirement after the identifier is obtained so as to obtain the final identifier. It should be noted that the number segment issuer service module may be used by the present application to acquire a unique identifier in the number segment cache region, or may be used by the number segment issuer number fetching module to acquire a unique identifier by a network request. In addition, if the application does not need to use the number segment sender service module, an http request can also be sent to the application using the number segment sender service module to acquire the unique identifier needed to be used by the service.
Specifically, the identifier generation system executes the following processes: (1) planning the whole interval, step length, modulus, remainder, preset adjustment factor and time threshold of the business name and number segment according to the factors such as system scale, business volume and the like; (2) when a user service request accesses an application server, the application can acquire an identifier from a local number segment number sender service module, and can also initiate a network request to other applications through a number sender number taking module to acquire the identifier; (3) the number segment generator service module generates a double-cache number segment generator in a memory according to the configuration in the table; (4) when the number segment generator triggers a preset threshold value to asynchronously update the number segment, the step length and the termination value of the number segment can be adaptively and iteratively changed according to the throughput, and the number segment is updated into a number segment database; (5) depending on the business application rules, conversion between identifiers of different formats may be performed.
