Thanks to Apache 2.0 licenses for ClickHouse and ecosystem projects, developers can build innovative analytics without spending a cent for proprietary licenses or expensive cloud services. However, there’s a lot more to make a developer happy:
- Builds that install in 60 seconds or less
- Run ClickHouse and your entire analytic stack in Kubernetes
- Robust client connectivity: Python, Javascript, C++, Golang, Java, ODBC
- Simple integration with Kafka for rapid data ingestion
- A wealth of features designed to solve problems like funnel analysis, last point queries, and pivoting results
- Ability to read directly from S3, MySQL, PostgresQL, Redis, and ODBC data sources
- Tight integration with popular visualization tools like Grafana, Superset, and Tableau.
