[jira] [Updated] (CALCITE-3535) EnumerableJoinRule: remove unnecessary Filter on top of INNER Join

     [ https://issues.apache.org/jira/browse/CALCITE-3535?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ruben Q L updated CALCITE-3535:
-------------------------------
    Description: 
With the implementation of CALCITE-2973, now EnumerableHashJoin supports all type of conditions (not just equi joins). However, there is still one TODO in EnumerableHashJoinRule that, in case of an INNER Join, creates a Filter with the non-equi conditions on top of the EnumerableHashJoin (created only with the equi-conditions), this filter is not really needed, since now EnumerableHashJoinRule can support the full condition, including the equi and non-equi items.
