Subject [jira] [Commented] (HBASE-17377) MemStoreChunkAllocator
Date Mon, 06 Mar 2017 09:46:33 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15896992#comment-15896992

Anoop Sam John commented on HBASE-17377:
----------------------------------------

MemstoreChunkAllocator keeps the map of chunkId -> chunkRef.  When the MSLAB is closed
and so chunks, these entries in map will get removed right? Looks good.   Do we have an E2E
impl (PoC) for the ChunkMap impl?  So we can have a PoC based perf test reading. Good work

> 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.
