Subject [jira] [Commented] (HBASE-13094) Consider Filters that are evaluated before deletes and see delete markers
Date Wed, 17 Aug 2016 17:00:32 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15424905#comment-15424905

Andrew Purtell commented on HBASE-13094:
----------------------------------------

bq. A wrinkle with #4 that occurred to me that than it would be possible to add two filters
on a scan/get, and the logic to combine their outcomes 

Except I would imagine we would not advertise the outcomes of two filter lists installed in
different phases of the scan are going to be transparently combined by the system. We'd be
clear in documentation that a filter list installed 'pre delete' is an advanced API, not meant
to be used unless you know what you are doing (like the CP API), and if you'd like to know
more please see HBASE-13094.

> That would be good for full control filtering of all cells, such as needed for some transaction
implementations.
