> The current IoTConsensus still serializes each request at the consensus layer when replicaNum = 1, which significantly increases the time spent at the consensus layer in the full-link tracking panel.

> Although ISSUE [4855|https://github.com/apache/iotdb/pull/8025] refactored the seriality-related code, the problem predates that refactoring. 
> This issue will avoid these unwanted serializations
