chenglei updated HBASE-26143:
-----------------------------
Description:
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
