Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure.
Fig. 1 is a schematic diagram of a system for batch generation of identification codes for distributed services in some embodiments of the present disclosure.
As shown in fig. 1, a system 100 for batch generation of identification codes for distributed services includes: an apparatus 110 for batch generating identification codes for distributed services (referred to as a batch generating identification code apparatus 110 for short) and a storage system 120. The storage system 120 includes: one or more of a cache system 121 and a database 122. The cache system 121 is, for example, a Remote Dictionary service (Redis) cache system, but is not limited to the illustrated example. The database 122 is, for example, a mysql database, but is not limited to the illustrated example. The apparatus for generating identification codes in batches 110 provides a service of generating identification codes in batches for distributed services for each client device 130 based on data stored in the storage system 120. The client device 130 identifies data in the distributed service by using the plurality of identifiers, and performs processing such as migration on the identified data, for example, migrating the identified data to a storage device.
Fig. 2 illustrates a flow diagram of a method for batch generation of identification codes for distributed services according to some embodiments of the present disclosure.
As shown in fig. 2, the method of this embodiment includes:
in step S210, the apparatus for generating an identification code in batch 110 receives an identification code batch acquisition request sent by the client device, where the identification (biz _ tag) of the distributed service and the number (amount) of identification codes requested to be acquired are included.
Wherein the identity of the distributed service (biz _ tag) is used to identify the different distributed services. When the client device requests to acquire the identification code, the client device needs to indicate which distributed service identification code is requested to be acquired.
In step S220, the apparatus 110 for generating an identification code in batch queries, according to the identifier (biz _ tag) of the distributed service and the number (amount) of identification codes requested to be obtained, whether the request for acquiring the identification code in batch exceeds the generation range of the identification code of the distributed service corresponding to the identifier from the storage system 120.
The device 110 for generating identification codes in batches sends an inquiry request to the storage system 120, wherein the inquiry request indicates whether the request for acquiring identification codes in batches exceeds the generation range of the identification codes of the distributed services corresponding to the identification codes, and the inquiry request carries the identification (biz _ tag) of the distributed services and the number (amount) of the identification codes requested to be acquired; the storage system 120 determines whether the sum of the current value (current _ value) of the identification code identifying the corresponding distributed service and the number (amount) of the identification codes requested to be obtained is greater than the maximum value (max _ value) of the identification code identifying the corresponding distributed service, returns the generation reference value of the identification code if the sum is not greater than the maximum value (max _ value), i.e., if the sum is not greater than the generation range, i.e., if the sum is greater than the generation range, returns the indication value exceeding the generation range.
The reference value for generating the identification code is, for example: the latest current value of the identifier of the distributed service corresponding to the identifier, which is determined according to the sum of the current value of the identifier of the distributed service corresponding to the identifier and the number of the identifiers requested to be obtained, is represented as current _ value ═ current _ value + amount, where current _ value on the right side represents the latest current value (the generated reference value), and current _ value on the left side represents the original current value. The indication value outside the generation range is, for example, 0.
In step S230, when the query result indicates that the generation range of the identification code identifying the corresponding distributed service is not exceeded, the apparatus 110 for generating identification codes in batch generates a plurality of identification codes according to the generation reference value of the identification code returned by the storage system and the number (amount) of the identification codes requested to be obtained, and returns the generated identification codes to the client device.
In some embodiments, generating the plurality of identification codes comprises: adding a sum value (current _ value-amount +1) obtained by adding 1 to a difference value between the latest current value (current _ value) of the identification code for identifying the corresponding distributed service and the number (amount) of the identification codes acquired by the request, and taking the sum value as a generation starting value of the identification code; and circulating according to the number of the identification codes required to be acquired on the basis of the generation initial value of the identification codes, increasing 1 to the numerical value of the identification code in each circulation to generate one identification code, and circulating for multiple times to obtain multiple identification codes.
In step S240, in the case that the query result indicates that the generation range of the identification code identifying the corresponding distributed service is exceeded, the apparatus 110 for generating identification codes in batches acquires a distributed lock to obtain the right to update the related data in the storage system 120; inquiring the maximum value (max _ value) and the step length (step) of the identification code for identifying the corresponding distributed service from the storage system 120 according to the identification (biz _ tag) of the distributed service; according to the maximum value (max _ value) and the step length (step) of the identification code for identifying the corresponding distributed service, recalculating the maximum value (max _ value) of the identification code for identifying the corresponding distributed service, and synchronizing to the storage system 120; the distributed lock is released, the authority to update the related data in the storage system 120 is handed over, and then the step S220 and the subsequent steps are continuously executed.
Wherein, recalculating the maximum value of the identification code identifying the corresponding distributed service is represented as: max _ value + step, where current _ value on the right side represents the latest maximum value recalculated, and current _ value on the left side represents the original maximum value.
And inquiring whether the request exceeds the generation range of the identification codes of the distributed services corresponding to the identification from the storage system according to the identification of the distributed services in the batch acquisition request of the identification codes and the quantity of the identification codes acquired by the request, and if not, generating a plurality of identification codes at one time according to the generation reference value of the identification codes returned by the storage system and the quantity of the identification codes acquired by the request, thereby improving the generation efficiency of a plurality of IDs. And the distributed lock is used for carrying out update control on related data in the storage system, so that the problem of data update conflict in a distributed service scene is solved.
The method for generating the identification code for the distributed service batch is described in conjunction with fig. 3-4, respectively, according to different deployments of the storage system 120.
In case the storage system 120 comprises a cache system 121 and a database 122, the method of generating identification codes for distributed service batches is described in connection with fig. 3.
And a database 122 configured to store the identification biz _ tag of the distributed service and store the maximum value max _ value and step size of the identification code of the distributed service, and to respond to the corresponding query request.
An exemplary Mysql database table is designed as follows:
| column name | Type (B) | Whether or not it is empty | Description of the invention |
| biz_tag | varchar(24) | N | Service identification, unique |
| max_value | bigint(20) | N | Maximum value of identification code |
| step | bigint(20) | N | Stride of cache system |
| desc | varchar(500) | Y | Description of the invention |
| created | datetime | N | Date of creation |
| modified | datetime | N | Modifying the date |
The cache system 121 is configured to store the identifier of the distributed service and the current value and the maximum value of the identifier of the distributed service, determine whether the sum of the current value of the identifier of the distributed service and the number of identifiers acquired by the request is greater than the maximum value of the identifier of the distributed service, and respond to a corresponding query request, and the like.
An exemplary Redis cache system (Redis for short) is designed as follows:
biz _ tag key
Value { "current _ value", "max _ value" }
Namely, a Redis cache system is constructed by taking the service identifier biz _ tag as a key and taking the current value current _ value and the maximum value max _ value of the identification code as values, and the maximum value max _ value of the cache system is consistent with the maximum value max _ value in the database.
Fig. 3 is a flowchart illustrating a method for batch generation of an identification code for distributed services according to further embodiments of the present disclosure.
As shown in fig. 3, the method of this embodiment includes: steps S31-S314.
Step S31: the client device 130 sends an identification code batch acquisition request, which includes the identification of the distributed service and the number of identification codes requested to be acquired; the apparatus 110 for generating the identification codes in batch queries whether the cache system 121 stores the relevant service identifier, that is, whether there is a biz _ tag in the key stored in the cache system 121, according to the service identifier (biz _ tag) transmitted by the client device 130 and the number (amount) of the identification codes acquired by the request.
Step S32: the caching system 121 returns the query result if it exists.
Step S33: the device 110 for generating the identification code in batch determines whether the cache system 121 has the service identifier biz _ tag transmitted by the client device according to the query result returned by the cache system 121, and if the service identifier biz _ tag does not exist, the step S34 is executed, and if the service identifier biz _ tag exists, the step S35 is executed.
Step S34: the apparatus 110 for generating identification codes in batches queries whether the database 122 stores the relevant service identifier according to the incoming service identifier (biz _ tag), and the database 122 returns a result, which includes: the result of the query is present or not, and, if present, the maximum value max _ value of the identification code of the distributed service corresponding to the identity biz _ tag (i.e., the maximum value of the identification code sequence).
Step S34.1: the device 110 for generating identification codes in batches determines whether the service identifier exists in the database 122 according to the query result returned by the database 122. If so, step S34.2 is entered, and if not, an error message is returned directly to the client device 130.
Step S34.2: the means 110 for batch generation of identification codes obtains the maximum value max _ value of the identification code sequence from the returned result.
Step S34.3: the apparatus 110 for generating identification codes in batches acquires distributed locks, and only when the distributed locks are acquired, the values associated with the identification code sequences can be initialized in the cache system 121.
Step S34.4: the apparatus 110 for batch generation of identification codes initializes the value of the identification code sequence in the cache system 121: current _ value is 0 and max _ value is max _ value (i.e., max _ value in the cache system 121 is initialized to max _ value returned by the database 122)
Step S34.5, after the device 110 for generating identification codes in batches releases the distributed lock, the process proceeds to step S35.
Step S35: the cache system 121 determines, according to the incoming biz _ tag, whether current _ value + amount is greater than max _ value (that is, determines whether the sum of the current value current _ value of the identification code of the distributed service corresponding to the service identifier biz _ tag and the number of identification codes amount requested to be obtained is greater than the maximum value max _ value of the identification code of the distributed service corresponding to the service identifier biz _ tag). If not, the process proceeds to step S36, and if so, the process proceeds to step S38.
Step S36: the cache system 121 sets a generation reference value of the identifier, which is, for example, the latest current value (current _ value on the left) of the identifier of the corresponding distributed service determined according to the sum of the current value (current _ value on the right) of the identifier of the corresponding distributed service and the number (amount) of identifiers requested to be acquired, and is denoted as current _ value ═ current _ value + amount.
Step S37: the caching system 121 returns the latest current value current _ value.
Step S38: the caching system 121 returns an indication value (e.g., 0) that is outside the generation range.
Step S39: the caching system 121 returns the result.
Step S310: the apparatus 110 for generating the identification codes in batches determines whether the result returned by the cache system 121 is greater than 0, if so, it indicates that the cache system 121 successfully returns the reference value for generating the identification codes, and then the process goes to step S311, and if not, it indicates that the number of the identification codes requested to be obtained exceeds the maximum value stored in the cache system 121, and then the process goes to step S312.
Step S311: the apparatus 110 for generating an identifier in batch uses a sum obtained by adding 1 to a difference value between the latest current value current _ value and the number amount of identifiers requested to be acquired, as a generation start value of the identifier, that is, a generation start value of current _ value-amount +1, according to the latest current value current _ value returned by the cache system 121.
Step S312: the device 110 for generating identification codes in batches acquires distributed locks, and only when the distributed locks are acquired, the data related to the identification code sequences in the database 122 and the cache system 121 can be changed.
Step S312.1: the device 110 for generating identification codes in batches queries the database 122 according to the biz _ tag, and obtains the max _ value and step returned by the database 122.
Step S312.2: the apparatus 110 for generating an identification code in batch is configured to recalculate the maximum value of the identification code identifying the corresponding distributed service according to the maximum value of the identification code identifying the corresponding distributed service and the step size to obtain the maximum value of the identification code identifying the corresponding distributed service, which is denoted as max _ value ═ max _ value + step, and synchronize the recalculated max _ value to the database 122.
Step S312.3: the apparatus for bulk generation of identification codes 110 synchronizes the recalculated max _ value to the cache system 121 so that the cache system 121 is consistent with the max _ value of the database 122.
Step S312.4: after the apparatus 110 for batch generation of the identification code releases the distributed lock, the process re-enters step S35.
Step S313: the apparatus 110 for generating identification codes in batches performs a cycle according to the number of identification codes requested to be obtained on the basis of the generation start value of the identification codes, that is, the cycle is performed by around, the value of the identification code is increased by 1 each time to generate one identification code, and a result set of a plurality of identification codes is obtained through multiple cycles.
Step S314: the means for bulk generation of identification codes 110 returns the result set to the client device 130.
And inquiring whether the request exceeds the generation range of the identification codes of the distributed services corresponding to the identification from the storage system according to the identification of the distributed services in the batch acquisition request of the identification codes and the quantity of the identification codes acquired by the request, and if not, generating a plurality of identification codes at one time according to the generation reference value of the identification codes returned by the storage system and the quantity of the identification codes acquired by the request, thereby improving the generation efficiency of a plurality of IDs. In addition, the distributed lock is used for carrying out update control on related data in the storage system, and the problem of data update conflict in a distributed service scene is solved. In addition, the cache system is matched with the database, related data are preferentially inquired and judged in the cache system, and the overall response efficiency of the storage system is improved.
In the case where the storage system 120 includes a database 122, a method of generating identification codes for distributed service batches is described in connection with fig. 4.
