> In HBASE-26412, once we found there is an error replicating the edits, we will trigger a flush, and in HBASE-26413, we are likely to also trigger a flush when the pending edits are too large.
> We should find a way to avoid flushing the region too much.
> And a failure of replicating usually means the region is moved or the target region server is crashed, only a flush after the secondary replica is online will be useful, so flushing the region lots of times before the scedondary replica online is just useless.
