Nick Dimiduk created HBASE-24464: ------------------------------------ Summary: 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 Reporter: Nick Dimiduk
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.
