Julian Hyde commented on CALCITE-3670:
--------------------------------------
Schemas live longer than connections. Closing a connection should not close
resources that belong to a schema, otherwise the next connection that uses that
schema will get an error.
Because schemas are so long-lived, people who implement schemas should think
VERY carefully about holding any resources. Usually better to hold the
resources only when the schema is being constructed.
> Add ability to release resources when connection is closed
