Hi All,

For testing of calcite generated DAG, I want to verify whether the correct
DAG is created with right operators and streams and whether properties are
set properly.

Is there any PrintWriter for the LogicalPlan object printing components of
DAG?

If not, I am planning to write one for Calcite testing.
I was wondering if that would be useful addition to apex-core for testing
purpose.

Please share your opinion.

Thanks,
Chinmay.
