Citus Unforks From PostgreSQL, Goes Open Source
When we started working on CitusDB 1.0 four years ago, we envisioned scaling out relational databases. We loved Postgres (and the elephant) and picked it as our underlying database of choice. Our goal was to extend this database to seamlessly shard and replicate your tables, provide high availability in the face of failures, and parallelize your SQL queries across a cluster of machines.
We wanted to make the PostgreSQL elephant magical.
