Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Referring to fig. 1, fig. 1 is a flowchart illustrating a storage cluster data synchronization method according to an embodiment of the present invention. The method comprises the following steps:
s101: the execution node acquires a data operation instruction sent by the service node; and the data operation instruction is sent to the service node by the client.
In order to solve the problem of poor data synchronization reliability in the data synchronization method in the prior art, execution nodes and service nodes are set in a distributed storage cluster. In the embodiment of the invention, each operation of a service node is completed by using a db-master process, each operation of an execution node is completed by using a secondary-db-master process, namely, a node running the db-master process is determined as the service node, and a node running the secondary-db-master process is determined as the execution node. In the distributed storage cluster, the master node generally completes various interworking with a client outside the cluster, the slave node is used for executing a received data operation instruction, the service node only needs to perform data communication with the client and the execution node, and fewer sub-acid resources are needed, so that preferably, a db-master process can be run on the master node, that is, the master node is set as the service node, and optionally, one slave node runs a secondary-db-master process, that is, optionally, one slave node determines the slave node as the execution node. Of course, there may be other determination schemes of the service node and the execution node, and this is not limited in the embodiment of the present invention.
The data operation instruction comprises instructions for performing operations such as adding, deleting and modifying on data and instructions for querying the data. After the service node acquires the data operation instruction sent by the client, the service node sends the data operation instruction to the execution node, and the execution node acquires the data operation instruction sent by the service node.
S102: and analyzing the data operation instruction, and determining a target node specified by the data operation instruction.
After the execution node obtains the data operation instruction, the data operation instruction is analyzed, and a target node specified by the data operation instruction is determined. Specifically, after the data operation instruction is analyzed, the target data can be determined, and the node in which the target data is stored is determined as a target node; or when the data operation instruction contains a specific node address, determining the node with the node address as a target node.
Further, in order to prevent the content of the data operation instruction from being incorrect, whether data specified by the data operation instruction exists in the cluster or not may be determined first, and if not, instruction error information is sent to the service node, and the service node sends the instruction error instruction to the client. Or whether the target node specified by the data operation instruction stores the data specified by the data operation instruction or not can be judged, if the target node does not store the data specified by the data operation instruction, the instruction error information is sent to the service node, and the service node sends the instruction error information to the client.
S103: and sending the data operation instruction to the target node.
After the target node is determined, the execution node sends the data operation instruction to the target node, so that the target node operates the designated data according to the data operation instruction. Specifically, when the data operation instruction is a data adding instruction or a data rewriting instruction, the data operation instruction is sent with the added data or the rewritten data, and when the target node receives the data operation instruction and the data sent with the instruction, the specified data is added or rewritten in a database corresponding to the target node; and when the data operation instruction is a data deletion instruction, the target node deletes the specified data in the corresponding database after receiving the data operation instruction.
By applying the storage cluster data synchronization method provided by the embodiment of the invention, the service node is used for acquiring the data operation instruction sent by the client and sending the data operation instruction to the execution node, and the execution node distributes the acquired data operation instruction to the target node. The service node is used for acquiring and sending the data operation instruction, the execution node is used for receiving the data operation instruction sent by the service node and distributing the data operation instruction to other nodes, and the service node only needs to communicate with one node of the execution node, so that the data operation instruction sent by the client can be acquired by utilizing more resources; the execution node is only used to distribute data manipulation instructions and therefore can distribute instructions using more computing resources. The work of the main node in the data synchronization method in the prior art is distributed to the service node and the execution node to be executed, and the service pressure is distributed to the two nodes, so that the service node and the execution node are not easy to generate process crash faults, the process crash faults of the service node and the execution node can be avoided, further, data loss is avoided, the data synchronization reliability of the distributed storage cluster is improved, and the problem of poor data synchronization reliability in the data synchronization method in the prior art is solved.
Based on the foregoing embodiment of the present invention, in order to ensure that the target node receives the data operation instruction, after sending the data operation instruction to the target node, the embodiment of the present invention may further include:
step 11: and judging whether the confirmation information sent by the target node is received.
The confirmation information is used to indicate that the target node has received the data operation instruction, and the specific form of the confirmation information is not limited in this embodiment. Specifically, it may be determined whether the acknowledgement information sent by the target node is received after the data operation instruction is sent to the target node for a period of time, for example, it may be determined whether the acknowledgement information sent by the target node is received after the data operation instruction is sent to the target node for 1 second. When the acknowledgement information sent by the target node is not received, step 12 is entered.
Step 12: and re-sending the data operation instruction to the target node.
And when the confirmation information sent by the target node is not received, the data operation instruction is considered to be lost in the sending process, and then the data operation instruction is sent to the target node again. Further, after the retransmission, the operation of determining whether the acknowledgement information sent by the target node is received may be performed again, and the retransmission may be performed again until the acknowledgement information sent by the target node is received when the acknowledgement information is not received.
In order to execute the retransmission operation, the data operation command needs to be stored in the corresponding database after being acquired so as to execute the retransmission operation. Furthermore, when the executing node fails, the executing node can be reselected from other slave nodes and manages the database in which the data operation instruction is stored, so that the situations that the data operation instruction is lost and the data in the cluster is not synchronous can be avoided.
By applying the storage cluster data synchronization method provided by the embodiment of the invention, after the data operation instruction is sent to the target node, whether the data operation instruction is received by the target node is judged by judging whether the confirmation information sent by the target node is received, and the data operation instruction is retransmitted when the confirmation information is not received, so that the target node is ensured to receive the data operation instruction.
Based on the foregoing embodiment of the present invention, in order to enable the client to know the execution condition of the data operation instruction, after sending the data operation instruction to the target node, the embodiment may further include:
and receiving operation completion information sent by the target node and sending the operation completion information to the service node. Specifically, after the target node completes the data operation instruction, operation completion information for the data operation instruction is sent to the execution node to indicate that the data operation instruction is completed. The execution node can send the operation completion information to the service node after receiving the operation completion information, so that the service node sends the operation completion information to the client and informs the client that the data operation instruction is completed.
In practical applications, when a node is expanded, that is, when a new slave node is added to a cluster, a master node needs to suspend providing of external services and suspend issuing of a data operation instruction, so as to complete full data synchronization. This may make it impossible to provide services to the outside, which may affect the execution of various services. To solve the problem, an embodiment of the present invention will describe a specific node expansion method, and refer to fig. 2 specifically, fig. 2 is a flowchart of a specific node expansion method provided by an embodiment of the present invention, including:
s201: and when the node expansion instruction is received, stopping receiving the data operation instruction sent by the service node.
The node expansion instruction is an instruction for node expansion of the cluster, and when the node expansion instruction is received, in order to perform full data synchronization operation on a newly added node, the node needs to execute a data operation instruction for stopping receiving data sent by the service node.
S202: and carrying out full data synchronization operation on the newly added nodes specified by the node expansion instruction.
Specifically, after stopping receiving the data operation instruction sent by the service node, the execution node generates a full data snapshot of the execution node, and sends the full data snapshot to each newly added node, so as to perform data synchronization with the newly added node. In the process, the service node can still receive the data operation instruction sent by the client, namely, the service is provided to the outside.
S203: and when the full data synchronization operation is completed, restarting to receive the data operation instruction sent by the service node.
By applying the node expansion method provided by the embodiment of the invention, the external service can be continuously provided when the cluster node is expanded, and the client can still send a data operation instruction to the service node without influencing the operation of the service.
