Example 1 with StreamingException

use of io.pravega.segmentstore.contracts.StreamingException in project pravega by pravega.

@Override
public CompletableFuture<Void> createStream(String streamName, Duration timeout) {
    ensureRunning();
    return CompletableFuture.runAsync(() -> {
        if (this.streamWriters.containsKey(streamName)) {
            throw new CompletionException(new StreamSegmentExistsException(streamName));
        }
        StreamConfiguration config = StreamConfiguration.builder().streamName(streamName).scalingPolicy(ScalingPolicy.fixed(this.testConfig.getSegmentsPerStream())).scope(SCOPE).build();
        if (!getStreamManager().createStream(SCOPE, streamName, config)) {
            throw new CompletionException(new StreamingException(String.format("Unable to create Stream '%s'.", streamName)));
        }
        int writerCount = Math.max(1, this.testConfig.getProducerCount() / this.testConfig.getStreamCount());
        List<EventStreamWriter<byte[]>> writers = new ArrayList<>(writerCount);
        if (this.streamWriters.putIfAbsent(streamName, writers) == null) {
            for (int i = 0; i < writerCount; i++) {
                writers.add(getClientFactory().createEventWriter(streamName, SERIALIZER, WRITER_CONFIG));
            }
        }
    }, this.testExecutor);

    ensureRunning();
    String parentName = StreamSegmentNameUtils.getParentStreamSegmentName(streamName);
    if (isTransaction(streamName, parentName)) {
        // We have a transaction to abort.
        return abortTransaction(streamName, timeout);
    } else {

            } else {
                throw new CompletionException(new StreamingException(String.format("Unable to delete stream '%s'.", streamName)));
            }
        }, this.testExecutor);
    }
}
