Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

Example 1

FIG. 1 is a flowchart of a method for allocating an identifier according to Embodiment 1 of the present invention. This embodiment is applicable to the case of allocating a corresponding identifier ID to each service data. The method may be performed by an identification distribution apparatus, which may be implemented in software and/or hardware, and integrated into a device with an information processing function, such as a server. As shown in Figure 1, the method specifically includes the following steps:

S110. When an identifier allocation request for the service data is received, determine a current value set corresponding to the service data.

The service data may refer to data to be stored under a certain service type. Exemplarily, the business type may be, but not limited to, a purchase business type, a sales business type, a warehouse-in business type, or a warehouse-out business type, and the like. The identification assignment request may refer to a request for assigning an identification ID to service data. The identifier allocation request may include, but is not limited to, the service identifier corresponding to the service data. The service identifier may be composed of, but not limited to, at least one of numbers, letters, Chinese characters and symbols, so as to distinguish different types of services. A numerical set may refer to a set consisting of multiple numerical values of different sizes. The data structure of the set of values can be, but not limited to, an array structure or a queue structure. The current value set may refer to the value set at the current moment corresponding to the service data. The current value set in this embodiment may change in real time with the identification allocation process, that is, each time an identification is allocated, the current numerical value set is missing one value.

The values in the current value set are pre-generated according to the target termination value corresponding to the stored service data and the first preset storage quantity. Each type of service data in this embodiment corresponds to a target termination value. The target termination value may refer to the maximum value in the current value set corresponding to the service data. The first preset storage quantity may refer to the total quantity of numerical values in the numerical value set before the identifier is not assigned, which may be preset based on business scenarios and requirements. Exemplarily, the first preset storage quantity may be set as the maximum capacity value of the value set.

Specifically, in this embodiment, a value set may be set for each type of service in advance, and the target termination value corresponding to each type of service may be stored. Each value in each value set may be generated according to the target termination value corresponding to the corresponding service and the first preset storage quantity. Exemplarily, the value of the first preset storage quantity before the target termination value and including the target termination value can be used as each value in the value set, for example, if the target termination value is 201, the first preset storage quantity is 100, Then the 100 values 102-201 can be added to the value set.

Specifically, when a client needs to store a service data in the client's background server, the client can generate an identification allocation request for the service data, and send an identification allocation request to the allocation server that executes the identification allocation method provided by this embodiment. Send the identity assignment request. When the distribution server receives the identification assignment request, it can parse the identification assignment request to obtain the business identification corresponding to the business data of the identification to be assigned, and based on the pre-stored correspondence between the business identification and the numerical value set, A value set corresponding to the service identifier obtained by analysis is determined and used as the current value set corresponding to the service data.

S120: Read the smallest value stored in the current value set, delete the read value in the current value set, and return the read value as an identifier of the service data.

Specifically, after the current value set corresponding to the service data is determined, the smallest value stored in the current value set can be sent to the client as the identifier of the service data, so as to realize automatic assignment of the identifier, and make the client The received identifier can be stored in the backend server as the identifier ID of the business data to be stored, so as to perform data association or upstream and downstream interaction later. After reading the minimum value in the current value set, it is necessary to delete the read minimum value from the current value set, so as to update the current value set in real time, so that each assigned identifier is the smallest value in the updated current value set. Numerical value, that is, the identifiers assigned each time are gradually increasing values, thereby realizing the absolute increment of the identifiers, and can effectively rank the business data or identify the sequence of the business data based on the identifiers, which is suitable for depending on the ID increment. It solves the problem of application limitations in the existing technology.

Exemplarily, when the value set is a value queue of a queue structure, S120 may include: taking out a value in the current value queue, and returning the taken value as an identifier of the service data, wherein each value in the current value queue is from small Arranged in order of largest.

Wherein, each value in the value queue follows the first-in, first-out value rule, that is, the value added to the value queue first can be taken out of the value queue first. Specifically, when adding multiple values of different sizes to the value queue, each value can be added to the value queue in ascending order, so that the smallest value can be directly taken from the head of the value queue as a service The identifier of the data is returned, and the minimum value taken out can be automatically deleted by means of a queue, thereby further improving the allocation efficiency.

In the technical solution of this embodiment, by presetting a corresponding value set for each service, the values in the value set can be generated according to the stored target termination value corresponding to each service and the first preset storage quantity, and each value set can contain multiple values of different sizes. When receiving an identification assignment request for business data, read the smallest value stored in the current value set corresponding to the business data, and delete the smallest value in the current value set, so as to update the current value set in real time, so that each time When assigning an identifier, the minimum value in the current value set is returned as the identifier of the business data, so that the size of the identifier can be used to reflect the sequence of business data storage, the absolute increment of the identifier is realized, and the scope of business application is expanded.

On the basis of the above technical solution, "determining the current value set corresponding to the service data" in S110 may include: acquiring the target first database identifier stored in the server; based on the preset correspondence between the service identifier and the value set The target service identifier corresponding to the service data is determined from the target first database corresponding to the target first database identifier, and the current value set corresponding to the target service identifier is determined.

The server may refer to the distribution server in this embodiment or an additionally set server. The first database may refer to a database for storing respective sets of numerical values. Exemplarily, the first database may be a Redis database having a Key-Value key-value pair, wherein the key information Key may be used to store the service identifier, and the value information Value may be used to store a corresponding set of values. There may be one or more first databases in this embodiment, and when there are multiple first databases, each first database stores various value sets. Each first database in this embodiment may be a distributed database cluster composed of multiple databases, so as to store more value sets and improve the scalability of the identification distribution service. The target first database may refer to the first database currently being used. The first database identifier may be composed of, but not limited to, at least one of numbers, letters, Chinese characters and symbols, so as to distinguish different first databases. The target service identifier may refer to the service identifier corresponding to the service data to be assigned the identifier.

Specifically, in this embodiment, the currently used target first database identifier can be pre-stored in the server, so that the target first database identifier can be obtained through the server, and the target first database identifier can be determined based on the target first database identifier, and the target first database identifier can be determined. According to the correspondence between the service identifier and the value set pre-stored in the target first database, the current value set corresponding to the target service identifier is obtained in the target first database.

Exemplarily, obtaining the target first database identifier stored in the server may include: obtaining the target first database identifier stored in the target server in the server cluster, wherein each server in the server cluster adopts the Zookeeper coordination service technology. server.

Among them, the Zookeeper coordination service technology is an open source distributed application coordination service, which can provide consistent service functions for distributed applications, such as distributed coordination/notification, configuration maintenance, distributed locks, and distributed queues. Each server in the server cluster stores the target first database identifier. The target server can refer to the server currently in use. After each server adopts the Zookeeper coordination service technology, it can automatically avoid the existence of single point problems, that is, when there is an abnormal situation in the currently used target server, it can automatically switch to other servers and obtain the target first database from other servers. identification, thereby ensuring that the stored target first database identification can always be obtained, and improving the availability of the identification distribution service.

On the basis of the above technical solution, "generating the value in the current value set according to the target termination value corresponding to the stored business data and the first preset storage quantity" may include: obtaining the target second database identifier stored in the server; The correspondence between the preset service identifier and the termination value and the target service identifier corresponding to the service data, obtain the target termination value corresponding to the target service identifier from the target second database corresponding to the target second database identifier; based on the preset value interval, taking the target termination value and the value of the second preset storage quantity before the target termination value as the value in the current value set, wherein the second preset storage quantity is the difference between the first preset storage quantity and 1.

Wherein, the second database may be used to store the termination value corresponding to each service. By using the second database to store each termination value, the situation of data loss after downtime can be avoided, thereby ensuring the persistence of data and improving the availability of the distribution service. There may be one or more second databases in this embodiment. When there are multiple second databases, each second database stores a respective termination value in order to avoid single point problems. The target second database may refer to the second database currently being used. The second database identifier may be composed of, but not limited to, at least one of numbers, letters, Chinese characters and symbols, so as to distinguish different second databases. The preset value interval may refer to an interval between two adjacent values, which may be determined in advance based on a business scenario. For example, the preset value interval can be set to 1.

Specifically, in addition to storing the target first database identifier, the server can also store the target second database identifier, so that the currently used target second database identifier can be obtained through the server, and the target second database identifier can be determined based on the target second database identifier. The second database can obtain the target termination value corresponding to the target service identifier in the target second database according to the correspondence between the service identifier and the termination value pre-stored in the target second database. The distance at every preset value interval before the target termination value can obtain the value of the second preset storage quantity, and each obtained value and the target termination value are added to the current value set, so that the current value set can be generated. For example, when the first preset storage quantity is 1000, that is, the second preset storage quantity is 999, the target termination value is 3001, and the preset value interval is 1, the value of the second preset storage quantity is: 2002-3000, At this point, the 1000 values 2002-3001 can be added to the current value set.

Embodiment 2

FIG. 2 is a flowchart of a method for assigning an identifier according to Embodiment 2 of the present invention. On the basis of the above-mentioned embodiment, this embodiment adds a step of “when it is detected that the current value set satisfies the preset supplementary condition, according to the stored The target termination value corresponding to the business data, to supplement the current value set”. The explanations of the terms that are the same as or corresponding to the above-mentioned embodiments are not repeated here.

Referring to FIG. 2 , the identification allocation method provided by this embodiment specifically includes the following steps:

S210, when receiving the identification allocation request for the service data, determine the current value set corresponding to the service data;

S220: Read the smallest value stored in the current value set, delete the read value in the current value set, and return the read value as an identifier of the service data.

S230. When it is detected that the current value set satisfies the preset supplementary condition, perform value supplementation on the current value set according to the target termination value corresponding to the stored service data.

The preset supplementary condition may refer to a condition that is satisfied when a value needs to be supplemented to the current value set, for example, there is no value in the current value set, or the value usage rate in the current value set is greater than or equal to the preset usage rate. For example, the default usage rate may be 70%.

Specifically, in this embodiment, the minimum value in the current value set is returned as the identifier of the service data, and after the minimum value is deleted, the current value set at this time is the deleted current value set, that is, the current value set is updated in real time The set of values after. By detecting whether the current value set satisfies the preset replenishment condition, it can be determined whether new values need to be added to the current value set for subsequent identification assignment. If it is detected that there is no value in the current value set or the value usage rate in the current value set is greater than or equal to the preset usage rate, it can be determined that the current value set needs to be supplemented with a value. At this time, the target corresponding to the business data can be used. The termination value determines new values, and adds these new values to the current value set to complete the value addition. Exemplarily, in this embodiment, an asynchronous thread can be started to detect whether the current value set satisfies the preset supplementary condition, so that the current value set can be supplemented in time in a more timely manner, so as to avoid too long waiting time for the identification allocation of other business data, Thereby, the efficiency of identification allocation is improved.

It should be noted that, after the current value set is determined in step S210, it is also possible to first detect whether the current value set satisfies the preset supplementary conditions, if not, the operation of step S220 can be performed; For the target termination value, the current value set is supplemented by the value, and the operation of step S220 is performed after the value is supplemented.

Exemplarily, in S230 "according to the target termination value corresponding to the stored business data, the current value set is numerically supplemented", can include: according to the target termination value corresponding to the stored business data and the third preset storage quantity. A termination value, and the stored target termination value is updated to the first termination value; each target value is generated according to the updated target termination value and the third preset storage quantity, and each target value is added to the current value set.

Wherein, the third preset storage quantity may refer to the storage quantity matching the preset supplementary condition. Exemplarily, when the preset supplementary condition is that there is no value in the current value set, the third preset storage quantity may be equal to the first preset storage quantity; when the preset supplementary condition is that the value usage rate in the current value set is greater than When equal to or equal to the preset usage rate, the third preset storage quantity may be equal to the preset usage rate of the first preset storage quantity. The first termination value may refer to the maximum value in the supplemented current value set. The target value may refer to the new value to be supplemented.

Specifically, in this embodiment, the sum of the target termination value and the third preset storage quantity may be used as the first termination value corresponding to the service data, and by updating the stored target termination value corresponding to the service data to the first termination value, So that the value after the first termination value can be supplemented next time, so that the value in the value set always increases gradually, thereby ensuring the absolute increase of the value. In this embodiment, each time the value is supplemented, the target termination value is updated once. When the current times value is supplemented, it is necessary to store the value of the third preset storage quantity before the updated target termination value and including the updated target termination value. as each target value. Each target value can be added to the current value set in ascending order, so that the minimum value in the current value set can be obtained more quickly and the allocation efficiency can be improved.

In the technical solution of this embodiment, after returning the minimum value in the current value set as the identifier of the service data, if it is detected that the current value set satisfies the preset supplementary condition, the value can be terminated based on the target corresponding to the service data, and timely The current numerical value set is supplemented by numerical value, so that the waiting time of the identification allocation request of other business data can be avoided too long, and the identification allocation efficiency is improved.

On the basis of the above scheme, in S230, "complementing the current value set with a value according to the target termination value corresponding to the stored service data" may include: detecting whether there is currently a preloading identifier corresponding to the service data; if so, stopping The operation of performing value supplementation on the current value set; if not, set the preload flag, perform value supplementation on the current value set according to the target termination value corresponding to the stored business data, and delete the preset loading flag after the supplementation is completed.

Wherein, the preloaded identifier may refer to an identifier used to reflect the current value supplementation being performed. Each service in this embodiment may correspond to a preloaded identifier. Exemplarily, various preloaded identities may be stored in the server for better coordination of services. Specifically, when it is detected that the current value set needs to be supplemented, it can be determined whether to perform a value supplement operation on the current value set by detecting whether a preloading flag corresponding to the service data is set in the server. If there is a preloaded identifier corresponding to the service data, it indicates that the current value set is being supplemented with the value of the identifier allocation request for other service data belonging to the same service type as the service data, and the current value set can be stopped at this time. The set performs the operation of numerical complementation. If there is no preloading flag corresponding to the business data, it means that there is currently no operation to supplement the current value set. At this time, the preloading flag can be set and the value supplementing operation can be performed. When the supplementation is completed, the preloading flag needs to be deleted. Therefore, the state of the current value set can be determined based on the preloaded identifier, thereby preventing concurrent operations and improving service performance.

On the basis of the above scheme, after updating the stored target termination value to the first termination value, the method further includes: storing the updated target termination value in the server when the times value is supplemented; When supplementing, if there is an abnormality in the target second database used to store the target termination value, the second termination value is determined according to the maximum target termination value stored in the server and the third preset storage quantity; the second termination value is stored in At the storage location corresponding to the business data in the standby second database, and based on the second termination value, the current value set is numerically supplemented; the target second database identifier stored in the server is updated to the identifier corresponding to the standby second database.

Specifically, in this embodiment, the determined first termination value can be stored in the server each time the value is supplemented, so that data recovery can be performed when the target second database is abnormal, thereby improving the availability of the distribution service. Exemplarily, if there is an abnormal situation in the target second database for storing the target termination value when the value is supplemented, that is, the target termination value cannot be obtained from the target second database, then the stored service data can be obtained from the server. The corresponding maximum target termination value, and the sum of the maximum target termination value and the third preset storage quantity is used as the second termination value, and the second termination value is stored by using the standby second database, and the target stored in the server is also used. The second database identifier is updated to the identifier corresponding to the standby second database, so that the target termination value can be directly read from the standby second database when the subsequent value is supplemented, thereby realizing the recovery of the target termination value. Numerical supplementation improves the availability of the second database and the performance of the allocation service.

Exemplarily, if there is an abnormality in the target second database used to store the target termination value, it is possible to first detect whether there is currently a second database switching identifier in the server, and if so, stop the "termination according to the maximum target stored in the server". value and the third preset storage quantity to determine the second termination value"; if not, the second database switching flag can be set, and execute "determine according to the maximum target termination value stored in the server and the third preset storage quantity" The second termination value is obtained, the second termination value is stored in the storage location corresponding to the business data in the standby second database, and the current value set is numerically supplemented based on the second termination value; the target second database stored in the server is identified. The operation of updating to the identifier corresponding to the standby second database", and after the execution ends, delete the switch identifier of the second database, so that concurrent operations of the switch of the second database can be prevented.

On the basis of the above solution, "when determining the current value set corresponding to the target service identifier in the target first database corresponding to the target first database identifier", it may also include: if there is an abnormal situation in the target first database, according to The target termination value corresponding to the stored business data is used to supplement the current value set corresponding to the business data in the standby first database; the target first database identifier stored in the server is updated to the identifier corresponding to the standby first database, so as to change from The current value set corresponding to the target service identifier is determined in the standby first database.

Specifically, if the target first database used for storing the current value set is abnormal, that is, the current value set cannot be obtained from the target first database, a new value can be determined based on the target termination value stored in the target second database , and add these new values to the current set of values in the standby first database. In this embodiment, the identifier of the target first database stored in the server is updated to the identifier corresponding to the standby first database, so that the current value set corresponding to the target service identifier can be determined from the standby first database, thereby ensuring that the current value set can always be obtained , which improves the availability of the first database and the performance of the allocation service. It should be noted that when the target first database is switched to the standby first database, since the current value set in the standby first database is an empty set, it is necessary to supplement the current value set in the standby first database in order to The identification assignment may be performed using the current set of values in the alternate first database.

Exemplarily, "complementing the current value set corresponding to the business data in the standby first database according to the target termination value corresponding to the stored business data" may include: detecting whether there is currently a first database switching identifier; if so, Then stop the operation of performing value supplementation on the current value set corresponding to the business data in the standby first database; if not, set the first database switching flag, and perform the operation of the standby first database according to the target termination value corresponding to the stored business data. The current numerical value set corresponding to the business data of the user interface is supplemented by the value, and after the supplement is completed, the first database switching identifier is deleted.

The first database switching identifier may refer to an identifier used to reflect the switching of the target first data. Exemplarily, the first database switching identifier may be stored in the server, so as to better coordinate the service. Specifically, when it is detected that there is an abnormality in the target first database, it can be determined whether to switch the target first database by detecting whether a first database switching flag is set in the server. If there is a first database switching identifier, it indicates that the target first database is being switched for the identifier allocation request of other service data belonging to the same service type as the service data, and the target first database can be stopped at this time. switching operation. If the first database switching flag does not exist, it indicates that the target first database is not currently switched. At this time, the first database switching flag can be set and the switching operation of the target first database can be performed. The numerical value set is supplemented with values, and the first database switching identifier needs to be deleted after the supplementation is completed, so that the state of the first database can be determined based on the first database switching identifier, thereby preventing concurrent operations and improving service performance.

The following is an example of the identification distribution device provided by the embodiments of the present invention, which belongs to the same inventive concept as the identification distribution methods of the above-mentioned embodiments. Embodiments of identity assignment methods.
