Example 16 with ChangeRecord

use of com.hazelcast.jet.cdc.ChangeRecord in project hazelcast by hazelcast.

the class MySqlCdcListenBeforeExistIntegrationTest method listenBeforeDatabaseExists.

@Test
public void listenBeforeDatabaseExists() throws Exception {
    List<String> expectedRecords = Collections.singletonList("1001/0:INSERT:TableRow {id=1001, value1=someValue1, value2=someValue2, value3=null}");
    StreamSource<ChangeRecord> source = sourceBuilder("cdcMysql").setDatabaseWhitelist(DATABASE).build();
    Pipeline pipeline = pipeline(source);
    // when
    HazelcastInstance hz = createHazelcastInstances(2)[0];
    Job job = hz.getJet().newJob(pipeline);
    assertJobStatusEventually(job, RUNNING);
    try {
        // then
        createDb(DATABASE);
