Subject [jira] [Commented] (HBASE-14511) StoreFile.Writer Meta Plugin
Date Tue, 29 Sep 2015 20:45:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14511?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14935829#comment-14935829

Vladimir Rodionov commented on HBASE-14511:
-------------------------------------------

Could be good help for Phoenix as well. SQL query optimizer can use additional meta sections
in a store files to keep relevent pieces of information (say, min-max order_date).

> During my work on a new compaction policies (HBASE-14468, HBASE-14477) I had to modify
the existing code of a StoreFile.Writer to add additional meta-info required by these new
 policies. I think that it should be done by means of a new Plugin framework, because this
seems to be a general capability/feature. 
> As a future enhancement this can become a part of a more general StoreFileWriter/Reader
plugin architecture. But I need only Meta section of a store file.
