Description
We use flushedSequenceIdByRegion and storeFlushedSequenceIdsByRegion in ServerManager to record the latest flushed seqids of regions and stores. So during log split, we can use seqids stored in those maps to filter out the edits which do not need to be replayed. But, those maps are not persisted. After cluster restart or master restart, info of flushed seqids are all lost.
Here I offer a way to persist those info to HDFS, even if master restart, we can still use those info to filter WAL edits and then to speed up replay.
