[jira] [Commented] (CALCITE-2827) Allow CONVENTION.NONE planning with VolcanoPlanner
[ https://issues.apache.org/jira/browse/CALCITE-2827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16779974#comment-16779974 ] Laurent Goujon commented on CALCITE-2827: - Didn't I answer it? Our planner has a planning phase when there's no convention change, but we are looking for a cost-based solution when applying different rules. Because NONE convention has always infinite cost, by default VolcanoPlanner cannot answer it. Note that if nodes were using a different convention, it would not be issue. I interpret this as VolcanoPlanner has an optimization to not compute cost for nodes with NONE convention since in most cases we are interested in finding the best solution in a different convention. But maybe that optimization could be generalized, and the optimization would be to not compute cost for the source convention, and make the optimization optional. If you think I merged the change too soon (but from [~michaelmior] PR comment, I didn't think it was too much controversial), I don't mind reverting. > Allow CONVENTION.NONE planning with VolcanoPlanner > -- > > Key: CALCITE-2827 > URL: https://issues.apache.org/jira/browse/CALCITE-2827 > Project: Calcite > Issue Type: Task >Reporter: Siddharth Teotia >Assignee: Juhwan Kim >Priority: Minor > Labels: pull-request-available > Fix For: 1.19.0 > > Time Spent: 40m > Remaining Estimate: 0h > -- This message was sent by Atlassian JIRA (v7.6.3#76005)

It would be great to hear the intention behind the change. Otherwise we get yet another configuration option to test and support for unknown reason. > Allow CONVENTION.NONE planning with VolcanoPlanner > -- > > Key: CALCITE-2827 > URL: https://issues.apache.org/jira/browse/CALCITE-2827 > Project: Calcite > Issue Type: Task >Reporter: Siddharth Teotia >Assignee: Juhwan Kim >Priority: Minor > Labels: pull-request-available > Fix For: 1.19.0 > > Time Spent: 40m > Remaining Estimate: 0h > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
