FeatureBase (formerly Pilosa) is a distributed analytical database built entirely on bitmap indexes, offering low-latency SQL queries over fresh batch and streaming data. The open-source Community edition is now archived and no longer maintained.

Use cases

  • run low-latency analytical queries on large datasets
  • ingest streaming data from Kafka into an OLAP database
  • store and query ML feature data efficiently
  • self-host a bitmap-indexed SQL database
  • analyze high-throughput event data in real time

When to choose

  • you need extremely fast ad-hoc analytical queries over bitmap-friendly data and can maintain the software yourself
  • you want a self-hosted, Apache-2.0 licensed OLAP engine with streaming and batch ingestion

When to avoid

  • you need a maintained database with active support and updates - the project is archived
  • you are looking for the Featurebase customer support/feedback SaaS product, which is an unrelated commercial tool
  • you need general-purpose transactional (OLTP) workloads
