Julian Hyde commented on CALCITE-2970: -------------------------------------- I take some of that back. I see that {{RelBuilder}} has a method {{RelBuilder transform(UnaryOperator<Config> transform)}} that creates a copy of a {{RelBuilder}} with the same state (including context, cluster) but a different config. So I think that {{UnaryOperator<Config> transform}} would be viable. > Performance issue when enabling abstract converter for EnumerableConvention > --------------------------------------------------------------------------- > > Key: CALCITE-2970 > URL: https://issues.apache.org/jira/browse/CALCITE-2970 > Project: Calcite > Issue Type: Bug > Components: core > Reporter: Haisheng Yuan > Priority: Major > Labels: pull-request-available > Time Spent: 18h 20m > Remaining Estimate: 0h > > If we enable the use of abstract converter for {{EnumerableConvention}}, by > making {{useAbstractConvertersForConversion}} return true, > {{JDBCTest.testJoinManyWay}} will not complete. -- This message was sent by Atlassian Jira (v8.3.4#803005)
