Description
Nowadays, Distributed Key-Value storage is extremely
useful in almost every large system. Most of the data
management systems use Distributed Key-Value database
in order to manage and process large volume of data in
real time. In such databases, Apache Cassandra is a peerto-
peer architecture which any user can connect to any
node in any data center and can read and write data
anywhere. Most of these systems usually select a fixed
number of replicas of read/write requests in Key-Value
storage. When the more replicas a read request chooses,
it may increase the response time and reduce the system
performance. Consistency in Key-Value data storage
systems requires any read operation to return the most
recent written version of the content. The system provides
transaction services which provide NoSQL databases with
enhanced consistency by varying the read and write
quorum size. The proposed approach tends to
automatically select the minimum number of consistent
replicas by predicting the staleness rate on adjusting the
consistency level.
