clickhouse.comrepositorydocspricing
ClickHouse is a column-oriented SQL database management system for online analytical processing. Its tables are stored as a collection of columns. It is written in C++, licensed under Apache-2.0 and maintained by ClickHouse, Inc., which also offers ClickHouse Cloud, built by its creators and maintainers.
The server runs as a long-running process on the machine or cluster it is installed on. The install guide offers a curl script, Docker images, Debian and Ubuntu packages, and rpm packages. The script downloads a single binary that also runs on a developer’s machine for local work.
Worth knowing
The open-source server and ClickHouse Cloud are separate deployments of the same database. Cloud pricing lists single sign-on and multi-factor authentication on its tiers, and a JWT option on the Enterprise plan. The self-managed server documents LDAP authentication, and the cloud features are not part of that server. The company’s own timeline puts the open-source release in 2016.
