Clustrix, Inc. is a San Francisco-based private company founded in 2006 that developed a database management system marketed as NewSQL.

Clustrix provides a distributed relational, ACID database that scales transactions[20] and support real-time analytics.

Other distributed relational databases are columnar (they don't support primary transaction workload) and focus on offline analytics and this includes EMC Greenplum, HP Vertica, Infobright, and Amazon Redshift.

[citation needed] NoSQL competitors, like MongoDB are good at handling unstructured data and read heavy workloads, but do not compete in the space for write heavy workloads (no transactions, coarse grained (DB-level) locking, and no SQL features (like joins), so the NewSQL and NoSQL databases are complementary.

[citation needed] The Clustrix database operates on a distributed cluster of shared-nothing nodes using a query to data approach.

This automatic data distribution approach removes the need to shard and enables Clustrix to maintain database availability in the face of node loss.

[24][25] Additional nodes added to the Clustrix cluster provided roughly linear increases in speed.
