testRedisStream

@Test
public void testRedisStream()
                     throws Exception

Verifies that all the records of a PostgreSQL table are streamed to Redis

Throws:

Exception

testRedisConnectionRetry

@Test
@FixFor("DBZ-4510")
public void testRedisConnectionRetry()
                              throws Exception

Test retry mechanism when encountering Redis connectivity issues: 1. Make Redis to be unavailable while the server is up 2. Create a new table named redis_test in PostgreSQL and insert 5 records to it 3. Bring Redis up again and make sure these records have been streamed successfully

Throws:

Exception

testRedisOOMRetry

@Test
@FixFor("DBZ-4510")
public void testRedisOOMRetry()
                       throws Exception

Test retry mechanism when encountering Redis Out of Memory: 1. Simulate a Redis OOM by setting its max memory to 1M 2. Create a new table named redis_test2 in PostgreSQL and insert 50 records to it 3. Sleep for 1 second to simulate Redis OOM (stream does not contain 50 records) 4. Unlimit memory and verify that all 50 records have been streamed

Throws:

Exception
