Subject [jira] [Commented] (HBASE-18010) Connect CellChunkMap to be used for flattening in CompactingMemStore
Date Mon, 22 May 2017 04:59:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16019138#comment-16019138

ramkrishna.s.vasudevan commented on HBASE-18010:
------------------------------------------------

bq.As our mapping is from Cell to Cell after this.delegatee.firstKey() or this.delegatee.lastKey()
we already have the correct Cell in our hands. Why do we do another logN traversal in this.delegatee.get()?
Looks like a waste of time...?
I think your point is valid. Since we already do a Cell-Cell mapping only, the key itself
is going to be the actual Cell. So ideally no need for doing a get().

> The CellChunkMap helps to create a new type of ImmutableSegment, where the index (CellSet's
delegatee) is going to be CellChunkMap. No big cells or upserted cells are going to be supported
here.
