Citus

Citus with multi-coordinator using Streaming Replication

In the standard setup of Citus, it has one coordinator, so it is the single point of failure and the bottle neck of the system.

To solve these disadvantages, I built a multi-coordinator using Streaming Replication, which is the built-in replication feature of PostgreSQL.


Citus with BRIN index

In this weekend, I tried Citus. The latest version of Citus is for PostgreSQL 9.5, so it can be used BRIN index.
