Przemo Pakulski commented on OAK-2777: -------------------------------------- We could do similar thing for unique property index, which I believe is (should be) as fast as reference index. > Minimize the cost calculation for queries using reference restrictions. > ----------------------------------------------------------------------- > > Key: OAK-2777 > URL: https://issues.apache.org/jira/browse/OAK-2777 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: core > Affects Versions: 1.1.2, 1.2 > Reporter: Przemo Pakulski > Attachments: oak-2777.patch > > > According to the javadocs (QueryIndex) minimum cost for index is 1. Currently > ReferenceIndex returns this minimum value, when it can be used for the query. > But even then cost for remaining indexes is still calculated. We could skip > cost calculation of remaining indexes if we achieved the minimum cost already. > It will speed up all queries which can leverage the reference Index. > Example query: > SELECT * FROM [nt:base] WHERE PROPERTY([rep:members], 'WeakReference') = > '345bef9b-ffa1-3e09-85df-1e03cfa0fb37' -- This message was sent by Atlassian JIRA (v6.3.4#6332)
