Subject [jira] [Commented] (HBASE-17377) MemStoreChunkAllocator
Date Mon, 06 Mar 2017 11:07:32 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15897100#comment-15897100

Anastasia Braginsky commented on HBASE-17377:

bq. MemstoreChunkAllocator keeps the map of chunkId -> chunkRef. When the MSLAB is closed
and so chunks, these entries in map will get removed right?


bq. Do we have an E2E impl (PoC) for the ChunkMap impl?

I personally do not have this implementation yet, but it looks like HBASE-16438 has the implementation.
I am willing to make the review to that patch on the Review Board asap. [~ram_krish], [~anoop.hbase]
please assist with publishing 16438's patch on the review board.

> Refactoring the separation between MemStoreChunkPool and (new) MemStoreChunkAllocator.
The latter allocates chunks either from heap or from pool and assigns them the Chunk IDs.
MemStoreChunkAllocator stores the mapping between chunks and their IDs.
