Example 1 with StreamInfo

use of io.pravega.controller.stream.api.grpc.v1.Controller.StreamInfo in project pravega by pravega.

the class ControllerImpl method getSegmentsAtTime.

    Preconditions.checkNotNull(stream, "stream");

    final CompletableFuture<SegmentsAtTime> result = this.retryConfig.runAsync(() -> {
        RPCAsyncCallback<SegmentsAtTime> callback = new RPCAsyncCallback<>();
        StreamInfo streamInfo = ModelHelper.createStreamInfo(stream.getScope(), stream.getStreamName());
        GetSegmentsRequest request = GetSegmentsRequest.newBuilder().setStreamInfo(streamInfo).setTimestamp(timestamp).build();
        client.getSegments(request, callback);
        return callback.getFuture();
    }, this.executor);
    return result.thenApply(segments -> {
        log.debug("Received the following data from the controller {}", segments.getSegmentsList());
