Announcing the release of TopN PostgreSQL extension

Posted on 2018-03-27 by Citus Data

Citus Data, is excited to announce the release of TopN, an open source PostgreSQL extension that returns the top values in a database according to some criteria. The TopN extension enables you to serve instant and approximate results to TopN queries. With the help of a very efficient approximation algorithm, TopN is able to materialize top values according to some criteria and incrementally update these top values, or merge them on-demand across different time intervals.

With TopN, you can:

  • Materialize your TopN results and update them incrementally.
  • Calculate TopN results approximately and very quickly.
  • Benefit the rich feature set of JSONB for your TopN datasets.

TopN is developed and maintained by Citus Data.
