ChistaDATA Inc. is a leading vendor of 24*7 consultative enterprise-class support, end-to-end managed services, bespoke production engineering, and cloud services for ClickHouse, the world's fastest (and open source) real-time analytics database management system.
Over the last few years, ChistaDATA has delivered enterprise-class support for hundreds of petabytes of data for some of the world's largest enterprises (see the list here). We maintain custom builds of ClickHouse developed specifically for customer use cases, i.e., forks of the community ClickHouse with community approved patches. We also author open source software tooling around ClickHouse such as the Anansi Query Profiler, the Asabru Proxy, etc. All of our software tooling is GPL-licensed and freely available to all community members, forever.
We also blog actively about ClickHouse internals, with ~500 articles in total available at our blog and knowledge base.
