[jira] [Resolved] (ASTERIXDB-969) Java OOM during recovery

     [ https://issues.apache.org/jira/browse/ASTERIXDB-969?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Murtadha Hubail resolved ASTERIXDB-969.
---------------------------------------
    Resolution: Fixed

Now that we have non-sharp checkpoint enabled, the probably of this issue happening is much less but still possible.
To completely eliminate the issue, the recovery analysis phase was redesigned to spill to disk. Each job has a limited amount of memory to use and once that amount is exceeded, the collected winner entities are spilled to disk and loaded on demand during the REDO phase.
