Subject [jira] [Commented] (HBASE-16421) Introducing the CellChunkMap as a new additional index variant in the MemStore
Date Wed, 02 Nov 2016 13:04:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16421?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15628899#comment-15628899
] 

stack commented on HBASE-16421:
-------------------------------

Thanks for updating the documents [~anastas]. There is an aside on speculative check '....although
the speculative check does...'. in IntroductiontoNewFlatandCompactMemStore.pdf.  Any chance
of more on how the check works? One thought looking at the pipeline is that flattening you
have to look at every key. Could you do the 'check-for-compaction-worthyness' at this time
since you are looking at keys anyway? (Would be optional?)
