Subject [jira] [Commented] (HIVE-14906) HMS should support an API to get consistent atomic snapshot associated with a Notification ID.
Date Wed, 12 Oct 2016 18:31:20 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15569504#comment-15569504

Sravya Tirukkovalur commented on HIVE-14906:
--------------------------------------------

Seems like if we do the following, we should be able to support an atomic getSnapshot() API:
- Set transaction level to "repeatable-read", so that all reads within a transaction would
be from a single generation point. In other words, concurrent writes would not affect the
state of the read.
- Make all the reads of snapshot building function part of the same transaction.
