title: Parallel query in HSQLDB
body: <p>is it possible to run query in parallel with HSQLDB? As i couldn't find anything in documentation, I suppose that optimizer has no parallelism included. But how about multiple database connections? Assume I have 2 threads working (and 2 cores available), each of them has a "private" (separate) connection to the database, and each of them tries to execute a different query (a query to a different table). Would such queries be executed in parallel?</p>
