Subject [jira] [Commented] (HBASE-13794) Add RegionLoad.getStorefiles(Bytes[] family)
Date Thu, 28 May 2015 17:20:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13794?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14563280#comment-14563280
] 

Jean-Marc Spaggiari commented on HBASE-13794:
---------------------------------------------

This is for manual compactions. On very big clusters (1K RS) with pretty big tables, and few
CFs, being able to see how many files we have on a CF for a given region will allow to save
a lot of IOs. 

Today I think this information is available using protobufadmin. Goal is not to keep this
information up to date and always available but being able to query that when required.

> RegionLoad already has getStorefiles but it might be very useful to get this information
per column familly instead of per region only.
