Node synchronization method and apparatus, device and storage medium

An electronic device, comprising:

• a memory and a processor, wherein
• the memory is storing a computer program;
• and
• the processor is configured to execute the computer program, wherein upon execution of the computer program, the processor is configured to:
• acquire node data sent by each slave node;
• obtain a target cluster parameter from each piece of node data, and obtain a standard cluster parameter by using the target cluster parameter based on an event queue length;
• determine an authorized slave node according to the standard cluster parameter, and judge whether a quantity of authorized slave nodes is greater than a quantity threshold;
• and
• in response to the quantity being greater than the quantity threshold, perform event playback on the authorized slave node by using a cluster event based on the standard cluster parameter;
• or
• in response to the quantity being not greater than the quantity threshold, control the authorized slave node to perform status synchronization on an unauthorized slave node, and perform event playback on the authorized slave node by using a cluster event after status synchronization.

A non-transitory computer-readable storage medium, storing a computer program executable by a processor, wherein upon execution by the processor, the computer program is configured to cause the processor to:

• acquire node data sent by each slave node;
• obtain a target cluster parameter from each piece of node data, and obtain a standard cluster parameter by using the target cluster parameter based on an event queue length;
• determine an authorized slave node according to the standard cluster parameter, and judge whether a quantity of authorized slave nodes is greater than a quantity threshold;
• and
• in response to the quantity being greater than the quantity threshold, perform event playback on the authorized slave node by using a cluster event based on the standard cluster parameter;
• or
• in response to the quantity being not greater than the quantity threshold, control the authorized slave node to perform status synchronization on an unauthorized slave node, and perform event playback on the authorized slave node by using a cluster event after status synchronization.
