Design and Architecture of the Boussole Real-Time Multi-Dimensional Data Analysis Engine

Boussole is Shopee’s real‑time analytics engine that transforms each dimension into key‑value pairs stored primarily in HBase, pre‑aggregates selected dimension combos, hashes metrics and tags, executes distributed PromQL queries with a CockroachDB‑inspired executor, applies Delta‑of‑Delta compression and point‑capping, and continues to evolve with adaptive pre‑aggregation and new storage models to maintain millisecond latency for massive multi‑dimensional analysis.

Shopee’s Logistics Channel Service migrated from a shared‑cluster MySQL setup to dedicated clusters, added TiDB for transient tracking data, and ultimately adopted hash‑based sharding with separate order and tracking services plus an asynchronous compensation mechanism, enabling uniform data distribution, cross‑database consistency, six‑month archiving, and scalable growth without rebalancing.
