Ted Yu commented on HBASE-19133:
--------------------------------
Can you describe the fix in more detail ?
Are you going to change the type of segment merge operation produces ?
> Transfer big cells or upserted/appended cells into MSLAB upon flattening to
> CellChunkMap

> CellChunkMap Segment index requires all cell data to be written in the MSLAB
> Chunks. Eventhough MSLAB is enabled, cells bigger than chunk size or
> upserted/incremented/appended cells are still allocated on the JVM stack. If
> such cells are found in the process of flattening into CellChunkMap
> (in-memory-flush) they need to be copied into MSLAB.
