[jira] [Commented] (HIVE-2147) Add api to send / receive message to metastore

    [ https://issues.apache.org/jira/browse/HIVE-2147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13046731#comment-13046731 ] 

John Sichi commented on HIVE-2147:
----------------------------------

I think we should close out this JIRA and create a new one specific to the latest approach.

Regarding the JDO change, instead of calling the table DONE_PARTITION_SET, I'd recommend naming it PARTITION_EVENTS, and add an EVENT_TYPE field containing values such as 'LOAD_DONE'.  This would allow for later adding new events such as 'LOAD_BEGIN'.  Then parameterize the API's accordingly.  Also, use EVENT_TIME instead of CREATE_TIME.

It seems like we're going to end up with sequential scans against this table?  Or is it going to be possible to index the searches on PARTITION_VALS?
