Yes, it fits in OS cache, that is the same case with parquet as well so it
would be fare comparison. What I am suggesting is now we run the queries of
parquet and carbon together. So there is a possibility of one engine jvm memory
consumption can effect the other engine. It would be better to run all the
queries of one engine and flush the GC and then start running other engine
queries.
