PERFORMANCE EVALUATION OF VARIOUS NOSQL DATABASES USING YCSB ON BASIS OF CRUD OPERATIONS USING PARALLEL VIRTUAL MACHINES

The advancement in internet technology, results in generating a large amount of data daily. Traditional databases are not capable of storing such huge data, as major concern is assess time, which is increased. So, the NO SQL database are capable of storing such huge data, with good access complexity. The major databases existing in market are Mongo, Cassandra, Hbase databases. These are major stake holders in market. In this paper, the performance of various NoSQL databases is evaluated using parallel virtual machines, i.e. using the threads. The tasks are executed in parallel, not only in single thread environment. The outcomes shows that Cassandra DB is outperformer database, whereas Mongo DB is suitable for smaller datasets. Hbase is good performer in between both the databases
