@roshannaik I ran the Exclamation topology with the TestWordSpout emitting
a tuple every 10 ms with a spout parallelism of 10 and measured the throughput
with and without event logger and I observed almost the same results.
I am also attaching the Jprofiler output after tracing the topology for
about 1.36 Million tuples where the send_to_eventlogger is consuming only
around 0.2% time.
