Subject [GitHub] flink issue #4722: [FLINK-7683] Iterate over keys in KeyedStateBackend
Date Wed, 27 Sep 2017 12:26:44 GMT
Github user pnowojski commented on the issue:

    We have got carried away with those concurrent modifications and snapshots. To rewrite
keyed state variable from an old to a new one, old is used as a read only. Thus `getKeys`
for the the old one doesn't have to care about any modifications. 
    I have reverted snapshot rocks db changes.
