Examples with TimeCacheMap org.apache.storm.utils.TimeCacheMap used on opensource projects

Example 1 with TimeCacheMap

use of org.apache.storm.utils.TimeCacheMap in project storm by apache.

the class CoordinatedBolt method prepare.

public void prepare(Map config, TopologyContext context, OutputCollector collector) {
    TimeCacheMap.ExpiredCallback<Object, TrackingInfo> callback = null;
    if (_delegate instanceof TimeoutCallback) {
        callback = new TimeoutItems();
    }
    _tracked = new TimeCacheMap<>(context.maxTopologyMessageTimeout(), callback);
    _collector = collector;
    _delegate.prepare(config, context, new OutputCollector(new CoordinatedOutputCollector(collector)));
    for (String component : Utils.get(context.getThisTargets(), Constants.COORDINATED_STREAM_ID, new HashMap<String, Grouping>()).keySet()) {
        for (Integer task : context.getComponentTasks(component)) {
            _countOutTasks.add(task);
        }
    }
    if (!_sourceArgs.isEmpty()) {
        _numSourceReports = 0;
        for (Entry<String, SourceArgs> entry : _sourceArgs.entrySet()) {
            if (entry.getValue().singleCount) {
                _numSourceReports += 1;
            } else {
                _numSourceReports += context.getComponentTasks(entry.getKey()).size();
            }
        }
    }
}

Example 2 with TimeCacheMap

    _collector = collector;
    int timeout = ((Number) conf.get(Config.TOPOLOGY_MESSAGE_TIMEOUT_SECS)).intValue();
    _pending = new TimeCacheMap<List<Object>, Map<GlobalStreamId, Tuple>>(timeout, new ExpireCallback());

    Set<String> idFields = null;
    for (GlobalStreamId source : context.getThisSources().keySet()) {
        Fields fields = context.getComponentOutputFields(source.get_componentId(), source.get_streamId());
        Set<String> setFields = new HashSet<String>(fields.toList());

                    _fieldLocations.put(outfield, source);
                }
            }
        }
    }
    _idFields = new Fields(new ArrayList<String>(idFields));
    if (_fieldLocations.size() != _outFields.size()) {
        throw new RuntimeException("Cannot find all outfields among sources");
    }
