Apache Pinot

Apache Pinot is a distributed, real-time OLAP datastore. It ingests data from batch sources such as S3 and Hadoop and from streams such as Kafka, offers pluggable indexes, and can be queried with SQL. It is developed by the Apache Software Foundation, and the project originated with engineers from LinkedIn and Uber. The software is licensed under Apache-2.0, so it is open source and free to use. Pinot is run self-managed, including on Kubernetes. A commercial offering from StarTree exists, but its details were not verified here, so buyers should check the vendor directly for terms and pricing. The latest release is 1.5.1, dated 5 June 2026, and it is a security patch release, so anyone running an earlier 1.5 version should plan to apply it. Because Pinot is a datastore built around real-time ingestion and indexed queries, it is most relevant to teams that need to serve analytical queries over fresh data, and that choose to operate the cluster themselves. No licence change, closed product line or dormant status was found, and the project remains active with recent releases.
