Examples with TransactionInfo com.facebook.presto.transaction.TransactionInfo used on opensource projects

Example 1 with TransactionInfo

use of com.facebook.presto.transaction.TransactionInfo in project presto by prestodb.

the class TestBrutalShutdown method testTransactionalQueryRetryOnShutdown.

@Test(timeOut = SHUTDOWN_TIMEOUT_MILLIS)
public void testTransactionalQueryRetryOnShutdown() throws Exception {
    try (DistributedQueryRunner queryRunner = createQueryRunner(ImmutableMap.of())) {
        executor.submit(() -> queryRunner.execute(TINY_SESSION, "START TRANSACTION")).get();
        TransactionInfo transactionInfo = queryRunner.getCoordinator().getTransactionManager().getAllTransactionInfos().get(0);
        Session session = testSessionBuilder().setCatalog("tpch").setSchema("tiny").setTransactionId(transactionInfo.getTransactionId()).build();
        // only send 1 query as the first failed query will abort the transaction
        queryRetryOnShutdown(session, queryRunner, executor, 1);
        List<BasicQueryInfo> queryInfos = queryRunner.getCoordinator().getQueryManager().getQueries();
        for (BasicQueryInfo info : queryInfos) {
            if (info.getQuery().contains("-- retry query")) {
                fail("no retry query is allowed within a transaction");
            }
        }
    }
}

Example 2 with TransactionInfo

use of com.facebook.presto.transaction.TransactionInfo in project presto by prestodb.

@Test
public void testStartTransaction() {
    Session session = sessionBuilder().setClientTransactionSupport().build();
    TransactionManager transactionManager = createTestTransactionManager();
    QueryStateMachine stateMachine = createQueryStateMachine("START TRANSACTION", session, true, transactionManager, executor, metadata);
    assertFalse(stateMachine.getSession().getTransactionId().isPresent());
    StartTransactionTask startTransactionTask = new StartTransactionTask();
    getFutureValue(startTransactionTask.execute(new StartTransaction(ImmutableList.of()), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).isClearTransactionId());
    assertTrue(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().isPresent());
    assertEquals(transactionManager.getAllTransactionInfos().size(), 1);
    TransactionInfo transactionInfo = transactionManager.getTransactionInfo(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().get());
    assertFalse(transactionInfo.isAutoCommitContext());
}

    StartTransactionTask startTransactionTask = new StartTransactionTask();
    getFutureValue(startTransactionTask.execute(new StartTransaction(ImmutableList.of(new Isolation(Isolation.Level.SERIALIZABLE), new TransactionAccessMode(true))), transactionManager, metadata, new AllowAllAccessControl(), stateMachine, emptyList()));
    assertFalse(stateMachine.getQueryInfo(Optional.empty()).isClearTransactionId());
    assertTrue(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().isPresent());
    assertEquals(transactionManager.getAllTransactionInfos().size(), 1);
    TransactionInfo transactionInfo = transactionManager.getTransactionInfo(stateMachine.getQueryInfo(Optional.empty()).getStartedTransactionId().get());
