Subject [jira] [Commented] (OAK-3085) Add timestamp property to journal entries
Date Wed, 08 Jul 2015 14:49:04 GMT

Chetan Mehrotra commented on OAK-3085:
--------------------------------------

Following comments
* We would need to index that field. So required index needs to be created in {{MongoDocumentStore}}
* For RDB I am not sure - I think this should be added as a first class column rather than
part of JSON. And yes an index should also be created

> OAK-3001 is about improving the JournalGarbageCollector by querying on a separated-out
timestamp property (rather than the id that encapsulated the timestamp).
> In order to remove OAK-3001 as a blocker ticket from the 1.2.3 release, this ticket is
about adding a timestamp property to the journal entry but not making use of it yet. Later
on, when OAK-3001 is tackled, this timestamp property already exists and migration is not
an issue anymore (as 1.2.3 introduces the journal entry first time)
