Mdrill is an open-source distributed OLAP (online analytical processing) engine from Alibaba's AdMom team, built in Java on top of JStorm/Hadoop-style infrastructure. It uses columnar storage, inverted indexes, compression, caching, and partitioning to deliver second-level ad-hoc queries over hundreds of billions of rows on as few as 10 commodity machines, with both offline batch and Kafka-based realtime ingestion.
Use cases
- run second-level ad-hoc analytical queries over hundreds of billions of rows
- analyze TB-scale data on a small cluster of commodity machines instead of an expensive data warehouse
- ingest billions of rows per day in realtime via Kafka
- do incremental partition-based updates of offline data
- slice and filter data across arbitrary combinations of 80-400 dimensions
- build a self-service big data analytics platform (like Alibaba's AdHoc)
When to choose
- you need low-cost, sub-minute ad-hoc OLAP queries over very large fact tables with many dimensions
- you want both realtime streaming ingestion and offline batch loading in one system
- you are running on a small on-premise cluster and cannot afford commercial distributed warehouses
When to avoid
- you need a maintained project - the repository was archived in October 2025 and the last release was in 2017
- your workload fits modern alternatives like ClickHouse, Druid, or Doris which have larger communities
- you need cloud-native deployment, rich SQL coverage, or an active ecosystem
