    Description

      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.
