15 Citus Data Testimonials

"Because Citus is open source and the metadata is accessible in normal Postgres tables, we were able to integrate it with our existing Spark infrastructure in a straightforward way."

"Scaling up our single-node Postgres deployment worked fine early on, but we knew it wouldn’t last. Our application grew faster than we anticipated. At one point, we had to email our customers to let them know we were working to fix the latency and performance issues. Now, with Citus, our query response times are less than 500 milliseconds for 97% of our queries."

"Usually for analytics applications, acceptable response times can be a matter of seconds. And this is especially true for long-term reporting that needs to query a huge amount of data. With Citus, it’s amazing. The response time on long-term queries of billions of rows is on the order of milliseconds. Citus is so darn fast!"

"With Citus, we really don’t have to think much about our database. It’s Postgres, it scales out, it works, and when we need help, we can get it. Citus really is worry-free."

"CitusDB enabled us to dramatically increase performance and cut costs. It has been a competitive and operational game-changer for our business."

"We bring in 25-30 billion rows of data a day. It’s not only massive amounts of data, but also massive amounts of traffic. We came to an industry that claimed that what we are doing is impossible. People laughed at us and said, ‘This is BS. It’s just not going to happen.’ To this day, people say that what we do is magic."

"We provisioned a new database using the Citus Cloud 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."

"Redshift wasn’t the right fit for a real-time web based dashboard with ad-hoc queries that need to return in sub-second times. The upfront execution plan compile time for each new ad-hoc query was too slow/variable. Citus’ real-time execution did not have that overhead and allowed us to have scale, speed, and dynamic ad-hoc queries."

"The speed change of Citus is a game changer. With Citus, we can make indexes in minutes that used to take hours."

"By adopting Citus Cloud to scale out Postgres, we didn’t have to slow down feature development to shard at the application level. For us, Citus was the fastest and best way to protect our engineering throughput while still scaling the database."

"At Algolia, our job is to provide the best search as a service, not to maintain clusters of PostgreSQL servers. We really wanted a database that scales, a database we wouldn’t have to worry about. Citus has given us that."

"Because CitusDB enables both real-time data ingest and sub-second queries across billions of rows, it quickly became the backbone of our customer analytics solution."

"Citus ​​makes ​​things ​​possible ​​for ​​us ​​that ​​would ​​have ​​been ​​nightmarish ​​in ​​a ​​NoSQL ​​world. Moving ​​to ​​Citus ​​has improved ​​the ​​reliability ​​and ​​performance ​​of ​​our ​​database, ​​and ​​the ​​fact ​​that ​​it's ​​not ​​a ​​black ​​box and ​​all ​​the ​​Citus ​​metadata ​​is ​​open ​​and ​​hackable ​​gives ​​us ​​a ​​lot ​​of flexibility."

"We expected a database migration to be a huge code change, requiring a lot of rewrites. But Citus has a Django multi-tenant library, which minimized the application refactoring we had to do to migrate our application. Except for rewriting a few lines of our app, we ended up using pretty much the same code."

"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."
