Example 9 with TransactionManager

use of org.apache.tephra.TransactionManager in project cdap by caskdata.

the class CubeDatasetTest method testTxRetryOnFailure.

@Test
public void testTxRetryOnFailure() throws Exception {
    // This test ensures that there's no non-transactional cache used in cube dataset. For that, it
    // 1) simulates transaction conflict for the first write to cube
    // 2) attempts to write again, writes successfully
    // 3) uses second cube instance to read the result
    //
    // In case there's a non-transactional cache used in cube, it would fill entity mappings in the first tx, and only
    // use them to write data. Hence, when reading - there will be no mapping in entity table to decode, as first tx
    // that wrote it is not visible (was aborted on conflict).
    Aggregation agg1 = new DefaultAggregation(ImmutableList.of("dim1", "dim2", "dim3"));
    int resolution = 1;
