Congxian Qiu(klion26) commented on FLINK-15507:
-----------------------------------------------
First, enable local recovery for incremental checkpoint has no overhead. and I
agree with [~Zakelly] that we should enable incremental checkpoint by
default(which has better performance).
For not incremental checkpoint with local recovery enabled, we'll consume more
disk(only the files in latest successfully checkpoint will be kept after
FLINK-8871 merged) but will give recovery when failover.
So from my side, enable local recovery for RocksDB StateBackend(incremental &
full snapshot) by default is fine to me.
