Heartbeat information sending method and apparatus, and heartbeat sending node

A heartbeat information sending method, wherein the method is performed by a heartbeat sending node, and the method comprises:

• determining a heartbeat receiving node in which one or more follower data blocks are located, wherein:
• the one or more follower data blocks belong to a data block group and a first data block located in the heartbeat sending node is a current leader data block for the data block group,
• a node identifier corresponding to the one or more follower data blocks incorrectly indicates that a second data block is the current leader data block for the data block group and that the second data block is located in a node other than the heartbeat sending node, and
• each follower data block and the corresponding leader data block belong to a same data block group;
• and
• sending heartbeat information of the heartbeat sending node to the heartbeat receiving node, wherein the heartbeat information of the heartbeat sending node carries a data block group identifier that identifies the data block group, and the data block group identifier indicates that the first data block is the current leader data block of the data block group.

A heartbeat sending node, comprising at least one processor, one or more memories coupled to the at least one processor, a transmitter, and a communications bus, wherein the processor and the transmitter communicate with each other by using the communications bus;

• the one or more memories storing programming instructions for execution by the at least one processor to determine at least one heartbeat receiving node in which at least two follower data blocks are located, wherein the at least two follower data blocks correspond to at least two leader data blocks that are located in the heartbeat sending node, and wherein each follower data block and the corresponding leader data block belong to a same data block group;
• and
• the transmitter is configured to:
• when the at least one heartbeat receiving node is a single node in which the at least two follower data blocks are located, send heartbeat information of the heartbeat sending node to the single heartbeat receiving node, wherein the heartbeat information is a combination of heartbeat information of each of the at least two leader data blocks and wherein the heartbeat information of the heartbeat sending node does not include heartbeat information of at least one follower data block that is located in the heartbeat sending node.
