Our Customers Love Using Worry-Free Postgres to Scale Out

Thanks to Citus, we’re powering a product that is really kind of magical for a lot of customers. The speed and performance of our database make it possible for them to immediately perform truly advanced analytics on any user activities they want to explore.

Dan Robinson, CTO at Heap

At Chartbeat, interactivity on our dashboards is very important. Every second a user has to wait, even if that request is crunching a lot of data, represents a potential disruption to our client’s workflow. In the past, it might have taken dozens of seconds or even minutes to materialize queries. With Citus, we can deliver sub-second latency.

Wesley Chow, CTO at Chartbeat

I like Citus’ combination of features, open source flexibility, and commercial-grade scalability. Best of all, because Citus is built on the latest version of PostgreSQL, we have been able to continue using the same core SQL toolset, leverage our existing PostgreSQL expertise, and take advantage of the continuing innovation within the PostgreSQL community.

Vidur Apparao, CTO at Agari

The biggest impact so far has been availability. We hit hard size limits on RDS sooner than anticipated, on Christmas morning in fact. Thankfully we already had a Citus system developed and in final testing. We were able to promote the Citus database to production with minimal downtime and zero loss of data.

Cody Koeninger, Chief Architect at Kixer

Being on a fully relational data model with the full indexing and querying power of Postgres was extremely valuable when it came to adding new analytics capabilities. Yet Citus also enabled us to maintain very fast response times, even with extremely complex queries.

Dan Robinson, CTO at Heap

We provisioned a new database using the Citus console, ran our migrations, copied over our data from Heroku, and we were up and running on Citus in just a few minutes. And the technical benefits were instant. We saw queries that were once taking 15-30+ seconds reduced to less than 500 ms.
