Why Coinbase and Pinterest Chose StarRocks: Lakehouse-Native Design and Fast Joins at Terabyte Scale

StarRocks is gaining traction among data engineers at companies like Coinbase, Pinterest, and Fresha as a high-performance OLAP engine capable of sub-second analytics on terabyte-scale data. The core differentiator over ClickHouse, Druid, and Pinot is native support for fast distributed joins via colocated join groups — tables sharing the same bucketing key, bucket count, and replica placement so joins happen locally without network shuffle. Coinbase uses StarRocks for crypto trade data with a hybrid hot/cold architecture: recent data in StarRocks native format on S3, cold historical data federated from Iceberg. Pinterest migrated from Druid and cut p90 query latency by 50% while using only 32% of prior infrastructure. Fresha achieved sub-100ms p95 web analytics queries. Key architectural decisions enabling this performance include a cost-based optimizer (CBO), delete-and-insert primary key updates, multi-tier caching (memory → local disk → S3), intelligent materialized views, and SIMD vectorized execution. Tradeoffs include a smaller community than ClickHouse, the need for careful upfront data modeling around partition and colocation keys, and occasional stability issues in new releases.
