About the project

chDB is an in-process OLAP SQL engine powered by ClickHouse, allowing applications to query analytical data without running a separate database server. Python users and data practitioners use it to work with formats such as Parquet, CSV, JSON, Arrow, and ORC through SQL or a pandas-compatible API. Its catalogue add-ons provide agent instructions, rules, skills, and an agent for working with the project.
