Josh Elser commented on HBASE-22566:
------------------------------------
{quote}Any reason to limit the flush speed by default? That's surprising, no?
{quote}
Actually, seems like I never looked close enough at
FlushThroughputControllerFactory. I thought the
PressureAwareFlushThroughputController was the default (like the
PressureAwareCompactionThroughputController was), but it is not. Doc patch is
wrong :)
> Call out default compaction and flush throttling for 2.x in Book

> We had it in the release notes, but it didn't make it into the upgrade path
> chapter of the Book ([https://hbase.apache.org/book.html#upgrade2.0]) that
> compactions and flushes are now limited in throughput per RegionServer.
> Came as a surprise to me the other day - I'm sure I won't be the last.
