Apache Pinot

Judgement

What it is

Building block

What it does

A distributed real-time analytics database that ingests from Kafka and batch sources and answers SQL queries over fresh data with low latency, with vector search as well.

Adopt it when

You need user-facing dashboards or analytics APIs that query large, constantly updating event data in well under a second.

Watch out

Running a Pinot cluster (controllers, brokers, servers, ZooKeeper) takes real operational effort, and it is a poor fit for transactional workloads.

Ready for

Production-ready

Runs as

Self-hosted server

Built with

Java, Kafka, ZooKeeper and TypeScript

How established
