[jira] Commented: (CAY-1465) Triggering removeGroup on
update/delete/insert query
[ https://issues.apache.org/jira/browse/CAY-1465?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12888284#action_12888284 ]
Andrus Adamchik commented on CAY-1465:
--------------------------------------
I suggest just map event listeners to do cache invalidation. Creating extra mapping rules seems like too much trouble.

> Key: CAY-1465
> URL: https://issues.apache.org/jira/browse/CAY-1465
> Project: Cayenne
> Issue Type: New Feature
> Components: Core Library
> Affects Versions: 3.0, 3.1M1
> Reporter: Evgeny Ryabitskiy
> Fix For: 3.1M1

> It can be useful for this case:
> I have 2 selects (NamedQueries) for table Artists, which have SHARED
> cache policy:
> MyArtistsSelectQuery1 from group ArtistsTableGroup:
> select * from Artists where isModern = 0
> MyArtistsSelectQuery2 from group ArtistsTableGroup:
> select * from Artists where isModern = 1
> And one insert:
> MyArtistsInsertQuery1
> insert into Artists values (....) .....
> Select NamedQueries are marked by properties in XML
> <property name="cayenne.GenericSelectQuery.cacheStrategy"
> value="SHARED_CACHE"/>
> <property name="cayenne.GenericSelectQuery.cacheGroups"
> value="ArtistsTableGroup"/>
> So, I would like to mark insert query as trigger for cache group
> removingin SHARED cache, like implicit execution of:
> domain.getQueryCache().removeGroup("ArtistsTableGroup");
> after successful insert.
> some property like:
> <property name="cayenne.GenericSelectQuery.removeGroups"
> value="ArtistsTableGroup"/>
> I think it can be very useful.
