Example 6 with Transaction

use of org.apache.distributedlog.util.Transaction in project bookkeeper by apache.

the class TestZKLogSegmentMetadataStore method testStoreMaxTxnId.

    Transaction<Object> updateTxn = lsmStore.transaction();
    Versioned<Long> value = new Versioned<Long>(999L, new LongVersion(0));
    final CompletableFuture<Version> result = new CompletableFuture<Version>();
    LogMetadataForWriter metadata = mock(LogMetadataForWriter.class);
    when(metadata.getMaxTxIdPath()).thenReturn(rootZkPath);
    lsmStore.storeMaxTxnId(updateTxn, metadata, value, new Transaction.OpListener<Version>() {

        @Override
        public void onCommit(Version r) {
            result.complete(r);
        }

        @Override
        public void onAbort(Throwable t) {
            result.completeExceptionally(t);
        }
    });
    Utils.ioResult(updateTxn.execute());
    assertEquals(1L, ((LongVersion) Utils.ioResult(result)).getLongVersion());
    Stat stat = new Stat();
