Subject [jira] [Updated] (PHOENIX-4095) Prevent index from getting out of sync with data table during partial rebuild
Date Thu, 17 Aug 2017 22:20:00 GMT

     [ https://issues.apache.org/jira/browse/PHOENIX-4095?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

James Taylor updated PHOENIX-4095:
----------------------------------
    Attachment: PHOENIX-4095_v1.patch

Please review, [~tdsilva]. This patch:
- ensures that the partial index rebuilder works under heavy load
- moves the logic to sort by time stamp into Indexer
- doesn't write to WAL during index rebuilding
- use thread local to carry state between coprocessor calls (due to lack of alternative)
- adds a bunch of high concurrency and other corner cases for the index rebuilder
