Subject [jira] [Commented] (HBASE-18994) Decide if META/System tables should use Compacting Memstore or Default Memstore
Date Tue, 24 Oct 2017 05:27:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16216337#comment-16216337

ramkrishna.s.vasudevan commented on HBASE-18994:
------------------------------------------------

If it is NONE - the default memstore is instantiated. If the config says do not use the default
memstore type then we make the inMemoryCompaction type as BASIC which will instantiate the
Compacting memstore and in Compacting Memstore BASIC is the default (since we also have EAGER).

> HBASE-18992 brought this topic. Currently META is also using Compacting Memstore. We
should decide if system tables can go with Default memstore only.
