Volodymyr Vysotskyi commented on CALCITE-2092: ---------------------------------------------- The reason for these changes is the same as in CALCITE-2043 - in Drill, we need to use our {{RelBuilder}} implementation with overridden {{empty()}} method. > Allow passing custom RelBuilder into SqlToRelConverter > ------------------------------------------------------ > > Key: CALCITE-2092 > URL: https://issues.apache.org/jira/browse/CALCITE-2092 > Project: Calcite > Issue Type: Bug > Reporter: Volodymyr Vysotskyi > Assignee: Julian Hyde > > Currently, {{SqlToRelConverter}} uses {{RelBuilder}} which was created in > such a way: > {code:java} > RelFactories.LOGICAL_BUILDER.create(cluster, null) > {code} > So it is not possible to use custom {{RelBuilder}} in this class. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
