Bryan Beaudreault commented on HBASE-26814:
-------------------------------------------
Yep was thinking something very close to that log.... "to enable, which may
help ease pressure under heavy write pressure".
I'm happy to do this, but you'll probably be the one merging it haha so if
you're already there that works for me too. Let me know and I can fire up a PR.
> Default StoreHotnessProtector to off, with logs to guide when to turn it on

> Key: HBASE-26814
> URL: https://issues.apache.org/jira/browse/HBASE-26814
> Project: HBase
> Issue Type: Improvement
> Reporter: Bryan Beaudreault
> Priority: Major
> Fix For: 2.5.0, 2.6.0, 3.0.0-alpha-3
>
>
> As discussed in HBASE-26522 and somewhat in HBASE-26575,
> StoreHotnessProtector is too conservative. One can easily trigger
> RegionTooBusyException on an otherwise idle regionserver with relatively
> small amount of traffic. The idea behind this protection is good, but it
> needs to take into account current load in order to warrant being enabled by
> default.
> Until it's improved as such, we should change it to default off. One thing we
> can do to help drive usage would be to add warning logs when it would have
> triggered. Operators who are diagnosing performance issues will naturally
> look at the logs and see indication of a potential tool for mitigation.
