> When users that are issuing InMemory Queries, the connection is released back to pool only after result set is read completely or after query is purged. 
> For InMemory Queries (not persisted by lens server), the query state is changed to SUCCESSFUL even before connection is released.
> This causes connection pool to throw error for new queries whenever JDBC driver is running at almost full load.
