NoSQL databases scale while standard SQL databases are consistent. NewSQL attempts to produce both features and find a middle ground. As a result, the database type solves the problems in big data fields.
This article gives an outline of NewSQL databases and their features.
What is NewSQL?
NewSQL is a unique database system that combines ACID compliance with horizontal scaling. The database system strives to keep the best of both worlds. OLTP-based transactions and the high performance of NoSQL combine in a single solution.
Enterprises expect high-quality of data integrity on large data volumes. When either becomes a problem, an enterprise chooses to:
- Improve hardware, or
- Create custom software for distributed databases
Both solutions are expensive on both a software and hardware level. NewSQL strives to improve these faults by creating consistent databases that scale.
NewSQL Database Features
The main features of NewSQL databases are:
- In-memory storage and data processing supply fast query results.
- Partitioning scales the database into units. Queries execute on many shards and combine into a single result.
- ACID properties preserve the features of RDBMS.
- Secondary indexing results in faster query processing and information retrieval.
- High availability due to the database replication mechanism.
- A built-in crash recovery mechanism delivers fault tolerance and minimizes downtime.
