Subject [jira] [Commented] (HIVE-20291) Allow HiveStreamingConnection to receive a WriteId
Date Thu, 02 Aug 2018 15:53:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-20291?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16566979#comment-16566979
] 

Eugene Koifman commented on HIVE-20291:
---------------------------------------

Is there a design description somewhere that explains what this is for and how it will be
used?
In particular, RandomStatementIdChooser?  If statement id is ever reused this will lead to
a data loss.

> If the writeId is received externally it won't need to open connections to the metastore.
It won't be able to the commit in this case as well so it must be done by the entity passing
the writeId.
