Example 6 with ArrayView

use of io.pravega.common.util.ArrayView in project pravega by pravega.

the class SegmentStoreAdapter method append.

@Override
public CompletableFuture<Void> append(String streamName, Event event, Duration timeout) {
    ensureRunning();
    ArrayView s = event.getSerialization();
    byte[] payload = s.arrayOffset() == 0 ? s.array() : Arrays.copyOfRange(s.array(), s.arrayOffset(), s.getLength());
    return this.streamSegmentStore.append(streamName, payload, null, timeout).exceptionally(ex -> attemptReconcile(ex, streamName, timeout));
}

Example 7 with ArrayView

use of io.pravega.common.util.ArrayView in project pravega by pravega.

the class InMemoryDurableDataLog method append.

@Override

    ensurePreconditions();
    CompletableFuture<LogAddress> result;
    try {
        Entry entry = new Entry(data);

            entry.sequenceNumber = this.offset;
            this.entries.add(entry, clientId);
            // Only update internals after a successful add.
            this.offset += entry.data.length;
        }
        result = CompletableFuture.completedFuture(new InMemoryLogAddress(entry.sequenceNumber));
    } catch (Throwable ex) {
        return Futures.failedFuture(ex);
    }
    Duration delay = this.appendDelayProvider.get();
    if (delay.compareTo(Duration.ZERO) <= 0) {
        // No delay, execute right away.
        return result;
    } else {
        // Schedule the append after the given delay.
        return result.thenComposeAsync(logAddress -> Futures.delayedFuture(delay, this.executorService).thenApply(ignored -> logAddress), this.executorService);
    }
