Case Study: Chartbeat achieves sub-second historical analytics, 10x faster queries, and scales to 2.6B rows/month with Citus Data

Chartbeat Delivers Historical Reporting & Content Intelligence to Digital Publishers with Citus Cloud

Chartbeat is a content‑intelligence platform used by 50,000+ publishers to analyze reader behavior and optimize engagement. When expanding from real‑time analytics to a historical analytics dashboard, Chartbeat needed a highly performant, multi‑tenant data store—one that could materialize complex aggregations, shard by customer, and handle rapidly growing data without forcing application‑level sharding work from its engineers.

Chartbeat chose Citus Cloud (a PostgreSQL extension) for fast, easy multi‑tenant sharding and reliable, familiar Postgres operations. Citus enabled a rapid AWS rollout, eliminated custom sharding, and gave Chartbeat sub‑second interactive queries and >10x faster responses while ingesting over 2.6 billion rows per month—letting the team focus on product innovation instead of database infrastructure.
