-------------------------------------------
Summary: Transfer big cells or upserted/appended cells into MSLAB
upon flattening to CellChunkMap
Key: HBASE-19133
URL: https://issues.apache.org/jira/browse/HBASE-19133
Project: HBase
Issue Type: Sub-task
Reporter: Anastasia Braginsky
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.
