[jira] [Comment Edited] (HBASE-20717) Implement CCSMap - a better concurrent map with compacted data structure

    [ https://issues.apache.org/jira/browse/HBASE-20717?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17166891#comment-17166891 ]

-------------------------------------------------------------

I'm going to further breakdown the HBASE-20717 into several tasks, since even CCSMap data structure part is huge.
The current PR and all upcoming is/will be based on https://issues.apache.org/jira/secure/attachment/12920186/HBASE-20312-master.v9.patch

PR: https://github.com/apache/hbase/pull/2165

The first one will be this: Chunk and ChunkPool structure. 
I did some refactoring and removed some fancy functions, for readability and quickly making it runnable. After then we can decorate it with the fancy parts.
