Yandex Managed Service for ClickHouse

ClickHouse is a fast open-source OLAP database management system. It is column-oriented and allows to generate analytical reports using SQL queries in real-time. ClickHouse's performance exceeds comparable column-oriented database management systems currently available on the market. It processes hundreds of millions to more than a billion rows and tens of gigabytes of data per single server per second. ClickHouse uses all available hardware to its full potential to process each query as fast as possible. Peak processing performance for a single query stands at more than 2 terabytes per second (after decompression, only used columns). In distributed setup reads are automatically balanced among healthy replicas to avoid increasing latency. ClickHouse supports multi-master asynchronous replication and can be deployed across multiple datacenters. All nodes are equal, which allows avoiding having single points of failure.

ChartDB is an open source, web‑based database diagramming tool that instantly visualizes your schema, whether from popular DBMSs like PostgreSQL, MySQL, SQL Server, SQLite, ClickHouse, and Oracle, or via a single query, without needing database access or complex setup. You can edit diagrams interactively using drag‑and‑drop, add annotations, or customize relationships, then export clean, dialect‑specific SQL DDL scripts or share diagrams as images. ChartDB Cloud accelerates workflows further with features like real‑time collaboration, live cursors, team avatars, and synced edits, plus auto‑saving of your work. Its AI assistant enhances productivity by detecting missing relationships, recommending foreign keys, and suggesting schema optimizations with a single click. Diagrams stay current through automated schema synchronization via a secure syncer CLI, ideal for CI/CD pipelines, preserving layout and styling even as your data model evolves.
