Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The message retransmission method for the service cluster can be applied to the application environment shown in fig. 1, wherein the database/cache platform can be implemented by an independent server or a server cluster formed by a plurality of servers, and the database platform and the cache platform can be deployed on the same server or different servers.
In an embodiment, as shown in fig. 2, a message retransmission method for a service cluster is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps S101 to S105.
S101, obtaining the identity of the equipment from a cache, and deleting the obtained identity of the equipment from the cache, wherein the identity of a plurality of pieces of equipment is stored in the cache.
The device corresponding to all the ids stored in the cache may be understood as forming a network device cluster for message retransmission service, and since the local server is also deployed in the network device cluster for message retransmission and the id of the local server is also stored in the cache, the id of the device acquired by the local server from the cache may be the id of the local server or the ids of other devices.
In one embodiment, the identity of the device identifies, for example, a physical number of the device.
In one embodiment, the cache stores the identity of the device via a two-tier storage structure.
The key at the first layer in the two-layer storage node represents the index of the index list, and the value of the key at the first layer comprises the identity of the equipment, the latest processing time of the message which fails to be sent by the equipment and corresponds to the identity, and the mark of the message which fails to be sent and is stored in the database corresponding to the identity. Wherein each device in the cluster of network devices of the message retransmission service stores a corresponding value in the first layer.
The key at the second layer in the two-layer storage node represents the identity of the equipment, and the value of the key at the second layer is an arbitrary value. The value of the two-tier key is, for example, 0. Wherein the identity of the device not being monopolized in the cluster of network devices served by the message retransmission is stored in the second layer of the cache.
It can be understood that, in the cached second layer data structure, the value specific value corresponding to the key is not important, and the identity of a certain device is stored as the key in the cached second layer data structure to indicate that the device is not exclusive.
Optionally, when the device is initialized, the initial time of the message retransmission time may be the initialization time of the device, when a retransmission message corresponding to the identity identifier is stored in the database, the flag of the retransmission message stored in the database is "yes", and when a retransmission message corresponding to the identity identifier is not stored in the database, the flag of the retransmission message stored in the database is "no".
Further, the step of deleting the acquired identity of the device from the cache in step S101 includes:
deleting the key value representing the identity of the device stored in the second layer of the cache.
S102, when the obtained identity is inquired from the database, a message of failed transmission of the equipment corresponding to the identity is obtained.
In one embodiment, the database stores the message with failed transmission and the identity of the device with failed transmission.
It will be appreciated that the identity of the corresponding failed transmitting device stored in the database is the original transmitting device of the failed transmitting message, and not the retransmitting device.
Optionally, the step of acquiring a message of failed transmission of the device corresponding to the identity identifier in this step includes:
and acquiring the messages which are failed to send and correspond to the identity identification from the database in batch according to the number of the preconfigured message acquisition pieces, and acquiring all the messages which are failed to send and correspond to the identity identification from the database when the number of the messages which are failed to send and correspond to the identity identification and are stored in the database is less than the number of the preconfigured message acquisition pieces.
In one embodiment, the number of message acquirements pre-configured in this step is, for example, 10 or 20.
Optionally, after the step of obtaining the identity of the device from the cache in step S101, the method further includes:
and when the obtained identity identifier cannot be inquired from the database, updating the mark of the retransmission message stored in the database stored in the first layer of the cache to be null.
Further, the message retransmission method for the service cluster further includes:
inquiring a mark of a retransmission message stored in a database corresponding to the identity of the equipment from the cached first layer structure;
the step S102 further includes:
and when the identity of the inquired equipment is corresponding to the mark of the stored retransmission message in the database, inquiring the obtained identity from the database.
In the embodiment, when the identity which cannot be obtained by querying from the database is found for the first time, the mark for storing the retransmission message in the database stored in the first layer of the cache is updated to be null, so that the problem that the invalid query cannot be performed from the database again when the identity is queried again in the later period can be avoided, the invalid access frequency of the database is reduced, and the database access pressure is relieved.
And S103, retransmitting the message with the failed transmission.
In one embodiment, the step S103 further includes:
and carrying out batch retransmission on the messages which are acquired from the database and have failed to be sent in batches and correspond to the identity identification.
S104, when the message which fails to be sent is successfully retransmitted, the message which fails to be sent and the identity of the corresponding device which fails to be sent which are stored in the database are deleted, and the identity of the device which corresponds to the message which fails to be sent is stored in the cache.
Optionally, after the step of S104, the message retransmission method of the service cluster further includes:
acquiring the processing time for retransmitting the message which fails to be transmitted;
and updating the latest processing time of the message which is stored in the first layer of the cache and fails to be sent to the acquired processing time.
In this embodiment, when a message that fails to be sent is retransmitted successfully, on one hand, the message that fails to be sent and the id of the device corresponding to the message that fails to be sent are deleted, so that the message that has been retransmitted and failed to be sent cannot be acquired again, thereby avoiding the message that fails to be sent being retransmitted repeatedly, and on the other hand, the id of the device corresponding to the message that fails to be sent is stored in the cache, so that the id corresponding to the device can still be acquired again, and when the id still corresponds to the message that fails to be retransmitted, other messages that have not been retransmitted and failed to be sent by the device can be acquired again, so that the message that has failed to be retransmitted cannot be retransmitted repeatedly, the message that has not failed to be retransmitted and is still stored in the database, the id corresponding to the message that has not failed to be retransmitted and is still stored in the cache, and other devices can acquire the message that has not failed to be retransmitted by caching the id, thereby continuing the retransmission.
S105, when the message which fails to be sent again, the message which fails to be sent and the identity of the corresponding device which fails to be sent which are stored in the database are reserved, and the identity of the device which corresponds to the message which fails to be sent is stored in the cache.
The message resending party of the service cluster proposed in this embodiment first acquires the id of a device from a cache, deletes the acquired id of the device from the cache, the ids of a plurality of devices are stored in the cache, then queries the acquired id from a database, acquires a failed transmission message of the device corresponding to the id when the acquired id is acquired from the database, resends the failed transmission message, deletes the failed transmission message and the id of the device corresponding to the failed transmission stored in the database when the failed transmission message is successful, stores the id of the device corresponding to the failed transmission message in the cache, when the failed transmission message is unsuccessful, retains the failed transmission message and the id of the device corresponding to the failed transmission stored in the database, stores the id of the device corresponding to the failed transmission message in the cache, and when the failed transmission message is unsuccessful, stores the history message and the physical number of the device transmitting the message in the cache in the same physical number in the cache, and deletes all the acquired messages from the physical number of the device corresponding to the failed transmission device in the cache by the physical number of the cache, and deletes all the failed transmission message from the physical number of the device in the cache, thereby enabling the device to be unable to be allocated from the cache. The method does not relate to a locking mechanism, the deadlock situation can not occur, and when other equipment cannot acquire the physical number of the equipment A from the cache, the other equipment also has a chance to acquire the physical number of the equipment B and the message failed to be sent by the equipment B, and the message failed to be sent by the equipment B is retransmitted, so that the waiting time of other equipment is reduced, the unnecessary performance loss of other equipment is avoided, and the overall performance of the system is improved.
Fig. 3 is a flowchart of a message resending method for a service cluster in another embodiment of the present invention, and further, the step of obtaining the identity of the device from the cache in step S103 specifically includes the following steps S301 to S303.
S301, acquiring each identity marked as a valid identity of the message failed to send and stored in the database from the first layer of the cache;
s302, sequencing the acquired identity identifications according to the latest processing time of the messages which are failed to be sent correspondingly to the identity identifications;
and S303, acquiring the identity of the equipment stored in the second layer of the cache from the sorting result according to the earliest and most preferred principle.
It can be understood that when the identity identifier marked as having the retransmission message stored in the presence database is not stored in the second layer structure of the cache, the message indicating that the transmission failure of the device corresponding to the identity identifier is being exclusively processed by other devices, and at this time, the local server is required to obtain the transmission failure message of the device corresponding to the other identity identifier.
In this embodiment, the obtained identifiers are sorted according to the latest processing time of the messages with the corresponding sending failures of the identifiers, and the identifier of the device stored in the second layer of the cache is obtained from the sorting result according to the earliest and most preferred principle, so that the messages with the sending failures occurring earlier can be preferentially retransmitted. And because the sorted objects are the identity identifications marked as the failed message which is stored in the database, the condition that the message cannot be found can not occur when the message is inquired from the database, and the effective execution capacity of the program is improved.
Fig. 4 is a flowchart of a message retransmission method of a service cluster according to another embodiment of the present invention; in this embodiment, when a newly sent message by the home server fails, the method for retransmitting a message of the service cluster further includes:
acquiring the time of failure in sending the message;
storing the identity of the server and the corresponding failed message in the database;
and updating the mark of the message which fails to be sent and is stored in the database corresponding to the identity of the server in the first layer of the cache to be present.
It can be understood that, in this embodiment, when a message newly sent by the home terminal server fails, the identity identifier of the server and the corresponding message that failed to be sent are stored in the database, and a flag of the message that failed to be sent is stored in the database corresponding to the identity identifier of the server in the first layer of the cache is updated to be present, so that both the message that failed to be sent by the home terminal server and the identity identifier of the home terminal server are stored, so that the home terminal server or another device in the network device cluster configured for the message retransmission service can obtain the identity of the home terminal server from the cache at a later stage, and then obtain the corresponding message that failed to be sent from the database for retransmission according to the information that the flag of the message that failed to be sent is stored in the obtained database is present.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

To avoid repetition, further description is omitted here.
The method, the apparatus, the computer device, and the storage medium for retransmitting a message of a service cluster according to embodiments of the present invention acquire an identifier of a device from a cache, delete the acquired identifier of the device from the cache, where the identifiers of multiple devices are stored in the cache, then query the acquired identifier from a database, acquire a message that fails to be sent of the device corresponding to the identifier when the acquired identifier is acquired from the database, resend the message that fails to be sent, delete the message that fails to be sent and the identifier of the device that fails to be sent, which are stored in the database, when the message that fails to be sent is resent successfully, store the identifier of the device corresponding to the message that fails to be sent in the cache, and when the message that fails to be sent is resent, retain the message that fails to be sent and the identifier of the device corresponding to be sent, which is stored in the database, and store the identifier of the device corresponding to the message that fails to be sent in the cache.
In this embodiment, the history failure message and the physical numbers of the devices that send the history failure message are stored in the database correspondingly, and the cache performs operations of sorting, deleting and adding on the physical numbers of all the devices deployed in the network device cluster for the message retransmission service, so that when one device preempts the physical number of the device a from the cache and acquires the message that the device a fails to send from the database, since the physical number of the device a has been deleted from the cache, other devices cannot acquire the physical number of the device a from the cache at the same time, so that other devices cannot acquire the message that the device a fails to send from the database, in the process of implementing retransmission of the history failure message, the lock mechanism is not involved, and a deadlock situation does not occur.
