[jira] [Commented] (OAK-3480) Query engine: faster cost calculation (take 2)

    [ https://issues.apache.org/jira/browse/OAK-3480?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14948710#comment-14948710 ] 

Thomas Mueller commented on OAK-3480:
-------------------------------------

Also, the NodeType index is asked unnecessarily if the property index returns cost of 2 (that is, with a unique index, and a lookup). One example is a UUID lookup query (where UUID = x).

> OAK-2679 improves cost calculation, however there is a small bug in the code that prevents the usage of getMinimumCost.
