## Shard your Postgres tables without blocking writes

New in the Citus 11.1 database, you can now distribute Postgres tables, split 
shards, and isolate tenants—without interruption, which means without blocking 
writes. Also included in 11.1 is PostgreSQL 15 beta 4 support, plus shard 
rebalancing in the background. Read [Marco’s blog 
post](https://www.citusdata.com/blog/2022/09/19/citus-11-1-shards-postgres-tables-without-interruption/)
 for the full story. Or if you’re more interested in the code you can check out 
the [Citus GitHub repo](https://github.com/citusdata/citus) (feel free to give 
the project a star to show support :) ).

## Citus is now 100% open source
In the last release (11.0), you gained the ability to [query from any 
node](https://www.citusdata.com/blog/2022/06/17/citus-11-goes-fully-open-source/),
 opening up Citus for many new use cases, and we also [made Citus fully open 
source](https://www.citusdata.com/blog/2022/09/12/distributed-postgres-goes-full-open-source-with-citus/).

## About the Citus database extension
Citus is a distributed database built entirely as an [open source extension for 
PostgreSQL](https://youtu.be/JwjjUT8K7po). With Citus, you can create tables 
that are transparently distributed or replicated across a cluster of PostgreSQL 
nodes. Citus is available as [open source](https://www.citusdata.com/download/) 
and also as a [managed service on Azure](https://aka.ms/docs-citus-on-azure).
