### What is Citus?
* **Open-source** PostgreSQL extension (not a fork)
* **Scalable** across multiple hosts through sharding and replication
* **Scalable** across multiple machines through sharding and replication
* **Distributed** engine for query parallelization
* **Highly available** in the face of host failures
* **Database** designed to scale multi-tenant applications
Citus horizontally scales PostgreSQL across commodity servers using
sharding and replication. Its query engine parallelizes incoming
SQL queries across these servers to enable real-time responses on
large datasets.
Citus is a distributed database that scales across commodity servers using transparent
sharding and replication. Citus extends the underlying database rather than forking it,
giving developers and enterprises the power and familiarity of a relational database. As
an extension, Citus supports new PostgreSQL releases, and allows you to benefit from new
features while maintaining compatibility with existing PostgreSQL tools.
Citus extends the underlying database rather than forking it, which
gives developers and enterprises the power and familiarity of a
traditional relational database. As an extension, Citus supports
new PostgreSQL releases, allowing users to benefit from new features
while maintaining compatibility with existing PostgreSQL tools.
Note that Citus supports many (but not all) SQL commands; see the
[FAQ][faq] for more details.
Citus serves many use cases. Two common ones are:
Common Use-Cases:
* Powering real-time analytic dashboards
* Exploratory queries on events as they happen
* Large dataset archival and reporting
* Session analytics (funnels, segmentation, and cohorts)
1. [Multi-tenant database](https://www.citusdata.com/blog/2016/10/03/designing-your-saas-database-for-high-scalability):
Most B2B applications already have the notion of a tenant /
customer / account built into their data model. Citus allows you to scale out your
transactional relational database to 100K+ tenants with minimal changes to your
application.
2. [Real-time analytics](https://www.citusdata.com/blog/2017/01/27/getting-started-with-github-events-data):
Citus enables ingesting large volumes of data and running
analytical queries on that data in human real-time. Example applications include analytic
dashboards with subsecond response times and exploratory queries on unfolding events.
