Examples with RetryListener io.crate.execution.support.RetryListener used on opensource projects

Example 1 with RetryListener

use of io.crate.execution.support.RetryListener in project crate by crate.

the class ShardingUpsertExecutor method execRequests.

private CompletableFuture<UpsertResults> execRequests(ShardedRequests<ShardUpsertRequest, ShardUpsertRequest.Item> requests, final UpsertResults upsertResults) {
    if (requests.itemsByShard.isEmpty()) {
        requests.close();
        // could be that processing the source uri only results in errors, so no items per shard exists
        return CompletableFuture.completedFuture(upsertResults);
    }
    final AtomicInteger numRequests = new AtomicInteger(requests.itemsByShard.size());
    final AtomicReference<Exception> interrupt = new AtomicReference<>(null);
    final CompletableFuture<UpsertResults> resultFuture = new CompletableFuture<>();
    Iterator<Map.Entry<ShardLocation, ShardUpsertRequest>> it = requests.itemsByShard.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry<ShardLocation, ShardUpsertRequest> entry = it.next();
        ShardUpsertRequest request = entry.getValue();
        it.remove();
        String nodeId = entry.getKey().nodeId;
        ConcurrencyLimit nodeLimit = nodeLimits.get(nodeId);
        ActionListener<ShardResponse> listener = new ShardResponseActionListener(numRequests, interrupt, upsertResults, resultCollector.accumulator(), requests.rowSourceInfos, nodeLimit, resultFuture);
        listener = new RetryListener<>(scheduler, l -> requestExecutor.execute(request, l), listener, BackoffPolicy.unlimitedDynamic(nodeLimit));
        requestExecutor.execute(request, listener);
    }
    return resultFuture.whenComplete((r, err) -> requests.close());
}
