        MessageMaps messageMaps) {//  w ww .j a va  2  s.  c  om
    this.groupBy = StringUtils.defaultString(groupBy);
    this.regenerateTemplate = regenerateTemplate;
    this.serializer = serializer;

    if (StringUtils.isNotBlank(groupBy)) {
        queueBuckets = threadCount;

        if (queueBuckets > 1) {
            queueThreadIds = new ArrayList<Long>(queueBuckets);
            hashFunction = Hashing.murmur3_32((int) System.currentTimeMillis());
            initialThreadAssignmentMap = new ConcurrentHashMap<String, Integer>(queueBuckets);
