Subject [jira] [Updated] (OAK-4725) Enable mmap mode by default for migration to SegmentNodeStore
Date Fri, 02 Sep 2016 09:22:21 GMT

     [ https://issues.apache.org/jira/browse/OAK-4725?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Julian Reschke updated OAK-4725:
--------------------------------
    Description: 
Currently in {{MigrationOptions}} in upgrade code the mmap option is only enabled if explicitly
enabled. 

Given it provides much better migration speed it would be better to enable it by default (at
least for non windows platforms) and provide a way to disable it by option. This would ensure
that migration uses most suitable options per default
