private TXId getNewTXId() {
    return new TXId(distributionMgrId,
        uniqId.updateAndGet(i -> i == Integer.MAX_VALUE ? 1 : i + 1));
  }
Get a new {@link TXId}.
This method builds a new {@link TXId} with uniqueID incremented by one.
Special case: If uniqueID has reached Integer.MAX_VALUE, then it is not incremented,
but set to one. This is done to prevent memory overflow of uniqueID to Integer.MIN_VALUE.
