[IOTDB-4209] Use .pst to accelerate recovery in SchemaFile mode

Open Cpaulyz opened this issue 3 years ago • 0 comments

Description

In the original process, recovery in SchemaFile mode will overwrite the .pst file and redo all the plans in MLog.

However, it causes unnecessary additional I/O cost. Therefore, the records in the mlog can be removed after flushing the .pst file. When recovering, we only need to redo the plans in the mlog that have not been persisted into the .pst file.
