Gali Sheffi commented on HBASE-19133:
-------------------------------------
Hey everybody!
We are sill fighting with QA, but would like to hear your thoughts about
committing this patch. Many people have done already the review on the RB.
Thank you [~ram_krish], [~tedyu], [~chia7712], [~anastas]! Please continue
reviews or let me know if you agree with committing (will be done by Anastasia
at the end).
So assuming the QA will eventually pass, what do you think about commit?
This is aimed to be committed both in master and in branch-2 in order to finish
the entire CCM feature.
Thanking you in advance!

> 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.
