[jira] [Commented] (PHOENIX-2896) Support encoded column qualifiers per column family

["James Taylor (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-2896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15282283#comment-15282283 ] 

James Taylor commented on PHOENIX-2896:
---------------------------------------

A little late, but I now remember why we were going to keep a count per column family for the column encoding - for the immutable tables. I think we can maintain both a global count (for mutable tables) and a per column family count (for immutable tables). Do you think you can keep the current logic, [~samarthjain], but add back the logic for per column family counts as well?

> This allows us to reduce the number of null values in the stored array that contains all columns for a give column family for the COLUMNS_STORED_IN_SINGLE_CELL Storage Scheme.
