NewSQL Databases are SQL databases that are used in a bid to achieve improved performance and scalability of NoSQL databases while maintaining all the benefits of relational database systems. Relational database systems have always been used by organizations to manage their data but the significant increase in the amount of complex data that organizations need to process has led to a search for a system that can provide availability, improved performance, and scalability. NewSQL databases maintain the ACID guarantees of DBMS, which ensure concurrent transactions, complete business processes, consistency before and after transactions, and data survival if there is system error or failure. NewSQL is an excellent option for handling complex data, and it guarantees data integrity in case of system error or failure. Some common features of a NewSQL database are replication, secondary indexes, sharding/partitioning, concurrency control, and crash recovery. NewSQL databases are preferred by many organizations to the relational database because they solve the major issues of the relational database without giving up the benefits of the relational database.
