Citus Data Powers MixRank's Customer Discovery Platform

CitusDB Database Enables MixRank to Use PostgreSQL to Make Tens of Terabytes of Time Series Data Immediately Available to Customers

SAN FRANCISCO, CA--(Marketwired - Jun 18, 2015) - Citus Data, which empowers real-time big data using PostgreSQL, today announced that MixRank has standardized on the CitusDB database platform to power its Customer Discovery Platform. MixRank is used daily by their customers' inside sales teams as a critical step in their workflows to narrow down and qualify B2B prospects and find new customers. With CitusDB, MixRank makes tens of terabytes of time series data immediately available to these teams. Serving as both a transactional and an analytics database, the CitusDB platform has enabled MixRank to scale its solution across a 20-node cluster of commodity servers. The result is a dramatic boost in performance and reduced cost and complexity, while leveraging all of MixRank's previous Postgres development efforts.


  • The MixRank platform was originally coded in PostgreSQL, a single-node database solution. CitusDB allowed MixRank to shard and scale out PostgreSQL across a cluster of commodity servers to manage big data. Because CitusDB did not need to pre-compute as many elements as standard PostgreSQL, customers began seeing real-time data, collected and inserted into the database minutes or even just seconds before their queries.
  • MixRank reduced its hardware budget by 50 to 100 times compared to what would have been required without CitusDB. MixRank used CitusDB to scale out using low-cost, commodity servers and remain on a single database technology. This provided major cost savings by eliminating costs related to maintaining multiple hardware platforms and software licenses. MixRank was also able to hire PostgreSQL experts for their database rather than database generalists in order to manage multiple platforms.
  • CitusDB is transparent to the application layer, so MixRank achieved the necessary scalability without a new development effort and was able to bring all the benefits of a relational database to its real-time big data efforts without any significant changes to its existing database applications. CitusDB extends rather than forks PostgreSQL, so MixRank was able to use its existing PostgreSQL tables, and a pilot program was very fast and easy to set up. CitusDB quickly proved to be highly reliable, massively scalable, and very fast.


Scott Milliken, CTO & co-founder of MixRank
"CitusDB allowed us to dramatically increase performance and cut costs. Because we could use our existing PostgreSQL tables, the pilot was very fast and easy to set up. We just had to make some minor changes to the backend structure. Most of our competitors still rely on daily batch updates, so this is a huge competitive differentiator for us. It has been a competitive and operational game-changer for our business."

Umur Cubukcu, CEO and co-founder of Citus Data
"CitusDB offers all the benefits of PostgreSQL plus it allows users to scale out their database platform and parallel process queries across a cluster of commodity servers. These capabilities enabled MixRank to collect and analyze real-time big data on an open source, clustered platform. As a hybrid transactional and analytics database, CitusDB enables organizations to power their operational and analytic initiatives on a single SQL platform, which results in unprecedented simplicity, scalability and cost management."
