Nick Dimiduk updated HBASE-24464:
---------------------------------
Component/s: Normalizer
> Normalizer should have configuration for minimum region size
> ------------------------------------------------------------
>
> Key: HBASE-24464
> URL: https://issues.apache.org/jira/browse/HBASE-24464
> Project: HBase
> Issue Type: Improvement
> Components: master, Normalizer
> Reporter: Nick Dimiduk
> Priority: Major
>
> Another issue raised in PR review on HBASE-24418. With the current
> implementation, the lower-bound on how small the normalizer will make a
> region is its lowest granularity of size measurement: 1mb. That means it will
> happily balance a table out to be 1000 * 1mb regions (probably not likely,
> but seems plausible). The proposal was to add configuration knob that
> specifies the lower bound on region size as a guard against excessive
> splitting, something of an analogue to {{hbase.hregion.max.filesize}}.
> I'm not convinced this is really needed; I think the table would need to have
> been crafted intentionally to trigger this behavior. However, it seems like a
> reasonable guard rail to install. Discuss.
