chenglei updated HBASE-26143:
-----------------------------
Summary: The default value of
'hbase.hregion.memstore.mslab.indexchunksize.percent' should be 0 (was: The
default value of 'hbase.hregion.memstore.mslab.indexchunksize.percent' should
depend on MemStore type)
> The default value of 'hbase.hregion.memstore.mslab.indexchunksize.percent'
> should be 0

> Key: HBASE-26143
> URL: https://issues.apache.org/jira/browse/HBASE-26143
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0-alpha-1, 2.4.0
> Reporter: chenglei
> Priority: Major
>
> The default value of {{hbase.hregion.memstore.mslab.indexchunksize.percent}}
> introduced by HBASE-24892 is 0.1, but when we use {{DefaultMemStore}} by
> default , which has no IndexChunk and {{ChunkCreator.indexChunksPool}} is
> useless(IndexChunk is only used by CompactingMemStore), so the
> {{hbase.hregion.memstore.mslab.indexchunksize.percent}} should be 0 when we
> using {{DefaultMemStore}} to save memory space. Only when we use
> {{CompactingMemStore}} and {{CellChunkMap}}, it is meaningful to set
> {{hbase.hregion.memstore.mslab.indexchunksize.percent}} by user.
> Howerver, because existing bug in {{ChunkCreator}}, it is depends on
> HBASE-26142
