Subject [jira] [Commented] (HBASE-13122) Improve efficiency for return codes of some filters
Date Wed, 04 Mar 2015 03:17:06 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13122?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14346312#comment-14346312

Shuaifeng Zhou commented on HBASE-13122:

That's a good point.
Accurately, there should be a return code "NEXT_FAMILY", so the return code should be next_family.
But currently, we have no this code. And if there is multi-family, next_row does the work,
scan jump to next family if return code is NEXT_ROW.
Maybe lately, we should add a return code "NEXT_FAMILY", but it's a big change ...
