[jira] [Resolved] (CALCITE-2277) Skip SemiJoin operator in materialized view-based rewriting algorithm

["Jesus Camacho Rodriguez (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CALCITE-2277?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jesus Camacho Rodriguez resolved CALCITE-2277.
----------------------------------------------
    Resolution: Fixed

For now, bailing out to prevent any incorrect result. If we want to support SemiJoin, algorithm will need to be extended, this may be done in a follow-up.

Fixed in http://git-wip-us.apache.org/repos/asf/calcite/commit/fd5dc8adf .

> {{AbstractMaterializedViewRule}} is not recognizing the difference between SemiJoin and Join operator, since SemiJoin inherits from Join. This can lead to incorrect rewriting and errors in the rewriting logic.
