Redis is a key-value (key-value) memory storage system that can be used as a data structure server, cache, and message queue agent. And data types such as character strings, hash tables, lists, collections, ordered collections, bitmaps, Hyperlogs and the like are supported. Because the redis has higher read-write performance, the application of the redis is more and more extensive.
In the use process of the redis, in order to improve the reliability of the redis, a master-slave service program/process is set in different servers, and the master-slave service program/process is managed by a monitoring module. When the main service program/process has a fault, the monitoring module switches the slave service program/process into the main service program/process and sends a notification message to each service network element needing to be accessed, so that each service network element modifies the stored IP address of the main service program/process, and the service network element can access the switched main service program/process according to the modified Internet protocol address of the main service program/process.
The serial number is a character string of key-value storage. In a distributed system, strings are quickly queried from a data structure server, such as redis, by key values.
Fig. 1 is a flow diagram illustrating a method of generating a sequence number in accordance with an example embodiment. The following is an example in which the method is applied to a serial number generation system. The serial number generation system comprises a terminal and a server. Various applications may be installed and run on the terminal, and may communicate with the server through the internet. Specifically, referring to fig. 2, fig. 2 is a schematic structural diagram illustrating a serial number generation system according to an exemplary embodiment, where the serial number generation system includes a terminal 201 and a server 202. The embodiment of the method for generating a sequence number shown in fig. 1 describes the steps of generating a monotonically increasing sequence number, which is applied to the terminal 201 and the server 202. The method comprises the following steps:
in step S101, when a sequence number generation request is received, a current service program identifier for generating the sequence number is acquired.
In this step, when receiving a serial number generation request issued by the terminal 201, the server 202 acquires a current service program identification for generating the serial number. It is understood that a service refers to a program, routine, process, or node in a redis cluster that performs specified system functions. For example, the current service identification of the host service that the server 202 obtained for generating the serial number is 10937.
In step S102, it is determined whether the current service program identifier used for generating the serial number is the same as the last service program identifier used for generating the serial number.
In this step, the server 202 determines whether the current service program identification used to generate the serial number is the same as the last service program identification used to generate the serial number. It is understood that a service refers to a program, routine, process, or node in a redis cluster that performs specified system functions. For example, the last service program that server 202 obtained in memory the main service program used to generate the serial number is identified as 12767. Server 202 compares current service identification 10937 with last service identification 12767 and determines whether the current service identification used to generate the sequence number is the same as the last service identification used to generate the sequence number.
In step S103, if the service program identifiers are not the same, the serial number is generated according to the current service program identifier.
In this step, if the current service program identifier used to generate the serial number is not the same as the last service program identifier used to generate the serial number, the server 202 generates the serial number from the current service program identifier. Then, the server 202 returns the generated serial number to the terminal 201. For example, when the server 202 compares the current service program identifier 10937 with the last service program identifier 12767 and determines that the current service program identifier used for generating the serial number is not the same as the last service program identifier used for generating the serial number, the serial number is generated according to the current service program identifier 10937.
According to an embodiment of the present application, when a serial number generation request is received, a current service program identification for generating a serial number is acquired. And judging whether the current service program identification used for generating the serial number is the same as the last service program identification used for generating the serial number. And if the current service program identifier used for generating the serial number is not the same as the last service program identifier used for generating the serial number, generating the serial number according to the current service program identifier. Whether the service program of the data structure server is subjected to master-slave switching or not is detected by comparing the service program identification of the master service program generating the serial number. Therefore, the monotone increasement of the generated serial number is ensured, and the efficiency of generating the serial number is improved.
Fig. 3 is a flowchart illustrating a method of generating a serial number, which is a key-value corresponding character string, according to an exemplary embodiment, including: first identification information and second identification information. The first identification information represents a current service program identification of a current main service program where a key value of the serial number is located, and the second identification information represents the number of times that the same main service program is continuously used for generating the serial number. It is understood that a service refers to a program, routine, process, or node in a redis cluster that performs specified system functions. The method comprises the following steps:
in step S301, when a sequence number generation request is received, a current service program identifier for generating the sequence number is acquired.
In this step, when a sequence number generation request is received, a current service identification for generating a sequence number is acquired. For example, the sequence number is a 16-byte character string. The current service identification is the service identification of the main service used to generate the current sequence number. It is understood that a service refers to a program, routine, process, or node in a redis cluster that performs specified system functions.
The serial number generation request may be that when a user performs a relevant operation (for example, login) on the client interface, which requires to establish communication with the server, the terminal running the client requests the server to create a session and requests to obtain a serial number uniquely identifying the created session. Alternatively, the user performs a related authentication operation (for example, a real-name authentication operation) based on the terminal, and the terminal sends a corresponding authentication operation request to the server and requests to acquire a serial number uniquely identifying the authentication operation request. In this embodiment, the use scenario in which the terminal sends the sequence number generation request is not limited.
In step S302, it is determined whether the current service program identifier used for generating the serial number is the same as the last service program identifier used for generating the serial number.
This step is identical to step S102 in fig. 1, and will not be described here.
In step S303, if the service identifier is not the same as the current service identifier, the serial number is generated according to the current service identifier and the current system time.
In this step, if the current service program identifier used for generating the serial number is not the same as the last service program identifier used for generating the serial number, the serial number is generated according to the current service program identifier and the current system time.
Specifically, the serial number includes first identification information and second identification information. And determining first identification information according to the current service program identification. The value of the preset number of bits may be selected from the current service program identifier as the first identifier information. For example, the first 8 bytes of value is selected from the current service program identifier as the first identifier information.
And determining second identification information according to the current system time. It may be that the current system time is acquired. The time format of the current system time is converted to a first format. The first format includes: timestamp format, plaintext format. And multiplying the current system time in the first format by a preset coefficient to obtain third identification information. The third identification information is an integer. And selecting a numerical value of a preset digit from the third identification information as second identification information. For example, the system time is represented by ts _ ms after the time format is converted into the millisecond timestamp format. The third identification information is ts _ ms × 1000000. And selecting the numerical value of the first 8 bytes from the third identification information as second identification information. It is to be understood that the manner in which the predetermined number of bits is selected should not be construed as limiting the present application.
And generating a serial number according to the determined first identification information and the second identification information. The first identification information and the second identification information may be used as part of a serial number to generate the serial number. For example, the first identification information is set as the high byte of the sequence number, and the second identification information is set as the low byte of the sequence number.
In step S304, if the serial numbers are the same, the serial numbers are generated according to the same service program identifier and the second identification information of the serial numbers generated last time.
In this step, if the current service program identifier used to generate the serial number is the same as the last service program identifier used to generate the serial number, the serial number is generated based on the same service program identifier and the second identification information of the last generated serial number.
Specifically, the serial number includes first identification information and second identification information. And determining first identification information of the current serial number according to the same service program identification. The value of the preset number of bits may be selected from the same service program identifier as the first identifier information. For example, the first 8 bytes of value is selected from the same service program identifier as the first identifier information.
Performing an increment operation on the second identification information of the last generated serial number to determine the second identification information of the current serial number. It may be that a preset incremental value is obtained. And carrying out incremental processing on the second identification information of the last generated serial number and a preset incremental value to obtain the second identification information of the current serial number. It is understood that the increment may be a linear increment, or may be other increment manners such as an exponential increment or an geometric increment, and should not be construed as a limitation to the present application.
And determining the current serial number according to the first identification information and the second identification information of the determined current serial number. The first identification information and the second identification information may be used as part of a serial number to generate the serial number. For example, the first identification information is set as the high byte of the sequence number, and the second identification information is set as the low byte of the sequence number.
If the current service program identification of the current main service program used for generating the serial number is different from the last service program identification used for generating the serial number, the fact that the master-slave service program is switched in the time interval of calling the main service program twice to generate the serial number indicates that the master-slave service program is switched in the redis. The switching of the master-slave service program may be the switching of a master-slave program, a routine or a process, or the switching of a master-slave node in a redis cluster. During the switching of the redis master-slave service program, some data may not be synchronized to the slave service program in time, and if the sequence number is directly incremented at this time, for example, by 1, the sequence number allocated by the old master service program may be reused, which violates the principle of incrementability.
Normally, the time consumed for switching between master and slave service procedures is >1ms, and the incrementability of the generated sequence number can be ensured as long as the number of the generated sequence numbers in 1ms is ensured to be less than 1000000, namely QPS is ensured to be less than 10 hundred million/second. The number of the generated serial numbers in the current redis 1ms is absolutely smaller than the value, so that the monotonous increment of the generated serial numbers can be ensured.
According to an embodiment of the present application, when a serial number generation request is received, a current service program identification for generating a serial number is acquired. And judging whether the current service program identification used for generating the serial number is the same as the last service program identification used for generating the serial number.
