Subject [jira] [Commented] (HBASE-19092) Make Tag IA.LimitedPrivate and expose for CPs
Date Tue, 31 Oct 2017 16:02:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16227033#comment-16227033

ramkrishna.s.vasudevan commented on HBASE-19092:

bq.Would this include means of building Tags?
Nope building tags I would go with RegionCPEnv method. That is better. Because only for CPs
we need to give that ability.
bq.We can figure this one I'd say.
Yes. For now won't worry about it.
So we have a cell with multiple Tags. We need a way to extract tags out from the cell and
once extracted we need APIs to work on individual tags.
My point was let us add all static helper methods to work on individual tag to the Tag interface.
Lets have LPCellUtil that will have all other static helper methods to work with cells and
extract out tags. In addition to that some of the APIs that I have listed in the above comment
will also be there. Makes sense?

>         Attachments: HBASE-19092-branch-2.patch, HBASE-19092_001-branch-2.patch
> We need to make tags as LimitedPrivate as some use cases are trying to use tags like
timeline server. The same topic was discussed in dev@ and also in HBASE-18995.
> Shall we target this for beta1 - cc [~saint.ack@gmail.com].
> So once we do this all related Util methods and APIs should also move to LimitedPrivate
Util classes.
