Subject [jira] [Updated] (HIVE-17629) CachedStore - wait for prewarm at use time, not init time
Date Fri, 29 Sep 2017 23:57:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-17629?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-17629:
------------------------------------
    Description: Most of the changes are trivial, due to static changing to non-static. The
patch basically adds lifecycle management for shared cache, and uses it to move prewarm to
background thread, waiting for prewarm to happen at use time not setConf, and to make init
optional (if not called, CachedStore would proxy the methods to rawStore, like it currently
does in the ones not implemented).
