------------------------------------
Summary: Connection config for enabling 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
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>
