Julian Hyde updated CALCITE-4552:
---------------------------------
Environment: (was: When closing Interpreter, close resources held by
its Nodes.
Currently, if a node is based on a JdbcTableScan, and the Interpreter's results
have not been read to completion, the statement will still be open, and the
JDBC connection will not be returned to the pool. This can cause a hang,
waiting for a connection, if you allocate and deallocate lots of Interpreter
instances.)
