Cnch

Cnch refers to a distributed columnar storage format designed for analytical workloads. It is an open-source project and is often associated with cloud-native data warehousing solutions. The format is optimized for high-speed querying of large datasets, particularly in scenarios where data is frequently read in columns rather than rows.

Key features of cnch include its columnar storage structure, which allows for efficient compression and reduced I/O operations for analytical queries. It supports various data types and encoding schemes to further enhance storage efficiency and query performance. The distributed nature of cnch enables it to scale horizontally, handling petabytes of data and supporting concurrent query execution across multiple nodes.

Cnch is designed to be compatible with various query engines and data processing frameworks, facilitating its integration into existing data pipelines. Its architecture typically involves a metadata layer for managing table structures and data locations, and a data layer for storing the actual data in a distributed and partitioned manner. This design aims to provide a cost-effective and performant solution for big data analytics in cloud environments.
