The Citus Data company founded in 2010 is engaged in development of the CitusDB mechanism allowing to pass from use of PostgreSQL on a separate node to parallel processing of data at once on several computing nodes and for this purpose it is not required to make changes on an applied layer of a system.
Citus Data uses PostgreSQL, the database management system, popular among developers, and will transform it to databases which can be distributed on several computers. It provides scaling of databases even for the most exacting applications to resources.
Citus is offered as completely managed service allowing to use PostgreSQL as service and also as a commercial product for the companies and the free open version (Open Source).
