Xiening Dai created CALCITE-3785: ------------------------------------ Summary: HepPlanner.belongToDag() doesn't have to use mapDigestToVertex Key: CALCITE-3785 URL: https://issues.apache.org/jira/browse/CALCITE-3785 Project: Calcite Issue Type: Bug Reporter: Xiening Dai
To test whether or not a vertex belongs to DAG, we can simply do graph.vertexSet().contains(vertex); There's no need to look up in mapDigestToVertex map, which incurs overhead of creating the map key. This problem was amplified by CALCITE-3713. -- This message was sent by Atlassian Jira (v8.3.4#803005)
