TJ Banghart updated CALCITE-7247:
---------------------------------
Summary: Add connection config to enable RuleMatchVisualizer (was:
Connection config for enabling RuleMatchVisualizer)
> Add connection config to enable RuleMatchVisualizer
> ---------------------------------------------------
>
> Key: CALCITE-7247
> URL: https://issues.apache.org/jira/browse/CALCITE-7247
> Project: Calcite
> Issue Type: New Feature
> Components: core
> Reporter: TJ Banghart
> Assignee: TJ Banghart
> Priority: Minor
>
> The RuleMatchVisualizer is a very useful debugging tool; however, I’ve found
> it somewhat difficult to use for ad-hoc queries or when working with plans
> outside of Calcite’s unit tests.
> I would like to add a Calcite connection configuration option that
> automatically attaches a RuleMatchVisualizer to any planner associated with
> that connection. This would make it easier to debug queries directly from
> sqlline or other tools over jdbc.
> For example:
> {code}
> sqlline> !connect jdbc:calcite:ruleVisualizerDir=/tmp/viz
> sqlline> SELECT * FROM emp;
> RuleMatchVisualizer enabled: Output will be written to /tmp/viz/<query_id>
> -- Results --
> {code}
