Julian Hyde created CALCITE-4552: ------------------------------------ Summary: Interpreter does not close resources held by its Nodes on close Key: CALCITE-4552 URL: https://issues.apache.org/jira/browse/CALCITE-4552 Project: Calcite Issue Type: Bug Environment: 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. Reporter: Julian Hyde -- This message was sent by Atlassian Jira (v8.3.4#803005)
