Citus Data - Distributed Postgres 
www.citusdata.com Citus Data | Distributed Postgres. At any scale.
Citus gives you all the greatness of Postgres plus the superpowers of distributed tables. By distributing your data and queries, your application gets high performance—at any scale. The Citus database is available as open source and as a managed service with Azure Cosmos DB for PostgreSQL.
Citus is a PostgreSQL extension that transforms Postgres into a distributed database—so you can achieve high performance at any scale.
With Citus, you extend your PostgreSQL database with:
- Distributed tables are sharded across a cluster of PostgreSQL nodes to combine their CPU, memory, storage and I/O capacity.
- References tables are replicated to all nodes for joins and foreign keys from distributed tables and maximum read performance.
- Distributed query engine routes and parallelizes SELECT, DML, and other operations on distributed tables across the cluster.
- Columnar storage compresses data, speeds up scans, and supports fast projections, both on regular and distributed tables.
- Query from any node enables you to utilize the full capacity of your cluster for distributed queries
Cloud Backed SQLite
The Cloud Backed SQLite system allows databases to be stored within cloud storage accounts such that they can be read and written by storage clients without first downloading the entire database to the client.
