Houliang Qi commented on IOTDB-723:
-----------------------------------
IMO, we can combine time-based method and number-based method together. Each
server periodically triggers the operation to check the deletion of the log. If
the distance between the last deletion log index and the current maximum
applied index exceeds a certain threshold, you can perform the deletion
operation, otherwise do nothing.

> Issue Type: Improvement
> Components: Core/Cluster
> Reporter: Tian Jiang
> Priority: Major
> Labels: cluster, log-serialization
