Anoop Sam John updated HBASE-19282:
-----------------------------------
Release Note: When MSLAB is in use (that is the default config) , we will
always use the CellChunkMap indexing variant for in memory flushed Immutable
segments. When MSLAB is turned off, we will use CellAraryMap. These can not be
changed with any configs. The in memory flush threshold been made to be
default to 10% of region flush size. This can be turned using
'hbase.memstore.inmemoryflush.threshold.factor'.

> We have made some experiments how working with CellChunkMap (CCM) influences
> the performance when running on-heap and off-heap. Based on those results it
> is suggested to tie the MSLAB usage (off-heap or on-heap) with CCM index
> usage.
