Examples with HashinatorSnapshotData org.voltdb.sysprocs.saverestore.HashinatorSnapshotData used on opensource projects

Example 1 with HashinatorSnapshotData

use of org.voltdb.sysprocs.saverestore.HashinatorSnapshotData in project voltdb by VoltDB.

the class TestTheHashinator method testSaveRestoreRaw.

@Test
public void testSaveRestoreRaw() throws Exception {
    if (hashinatorType == HashinatorType.LEGACY)
        return;
    ElasticHashinator h1 = new ElasticHashinator(ElasticHashinator.getConfigureBytes(3, ElasticHashinator.DEFAULT_TOTAL_TOKENS), false);
    byte[] bytes = h1.getConfigBytes();
    HashinatorSnapshotData d1 = new HashinatorSnapshotData(bytes, 1234);
    InstanceId iid1 = new InstanceId(111, 222);
    ByteBuffer b1 = d1.saveToBuffer(iid1);
    ByteBuffer b2 = ByteBuffer.wrap(b1.array());
    HashinatorSnapshotData d2 = new HashinatorSnapshotData();
    InstanceId iid2 = d2.restoreFromBuffer(b2);
    assertEquals(iid1, iid2);
    assertTrue(Arrays.equals(d1.m_serData, d2.m_serData));
    ElasticHashinator h2 = new ElasticHashinator(d2.m_serData, false);
    assertEquals(h1.getTokens(), h2.getTokens());
}
