Actually i dont have any issue with read and write,If you have 
experience with Cassandra NoSQL database,Its very read and write 
intensive.It will approximately  doing 10 Million concurrent   read and 
writes.AS per Cassandra documentation "/Cassandra can write 50GB of data 
in 0.12 milliseconds, more than 2,500 times faster than MySQL./"
