public class BigdataConnectionTest
extends RepositoryConnectionTest

Bigdata uses snapshot isolation for transactions while openrdf assumes that any writes committed by a transaction become immediately visible to transactions which are already running. Several unit tests from the base class have to be overridden bigdata has stronger semantics for transactional isolation.

tearDown

public void tearDown()
              throws Exception

Overridden to destroy the backend database and its files on the disk.

Overrides:

tearDown in class RepositoryConnectionTest

testOrderByQueriesAreInterruptable

public void testOrderByQueriesAreInterruptable()
                                        throws Exception

This test was failing historically for two reasons. First, it would sometimes encounter a full GC pause that would suspend the JVM for longer than the query timeout. This would fail the test. Second, the query engine code used to only check for a deadline when a query operator would start or stop. This meant that a compute bound operator would not be interrupted if there was no other concurrent operators for that query that were starting and stoping. This was fixed in #722.

Overrides:

testOrderByQueriesAreInterruptable in class RepositoryConnectionTest

Throws:

Exception

Query timeout only checked at operator start/stop.
