Joseph Eid commented on CALCITE-5224:
-------------------------------------
Hello [~jingzhang], first of all thanks for the quick response!
When executing a query with, the {{Prepare}} (impl) class calls this method
with the default value just before creating a {{SqlToRelConverter}} object see
{{{}prepareSql{}}}.
So in different words, how could I set the in subquery threshold when executing
queries via JDBC?
* Is there for instance a way to let Calcite use my own customised Prepare
implementation and/or SqlToRelConverter instead of the default one? and how?

> Currently, {{SqlToRelConverter}} instances always use a config with
> hard-coded threshold of 20.
> I can't find any parameters (or a way) to change that as it happens very
> early when preparing the SQL statement.
> Would be make this configurable from the outside.
