README

Unofficial ADO.NET client for ClickHouse®, ultra-fast 'big data' relational database

Not affiliated with or endorsed by ClickHouse Inc.

High-throughput
Fully supports ClickHouse-specific types:
- Composite types: Array, Tuple, Nullable, Nested, Map, including combinations
- Specialized types: IPv4, IPv6, UUID, DateTime64, LowCardinality, Enum etc.
- Large arithmetic types: (U)Int128, (U)Int256, Decimal128, Decimal256
Correctly handles DateTime, including time zones
Supports bulk insertion
Uses compressed binary protocol over HTTP(S)
Available for .NET Core/Framework/Standard

Compared to other existing .NET clients, ClickHouse.Client has following advantages

Does not have to buffer response, reducing memory usage
Offers wider support for ClickHouse-specific types
Is more compliant to ADO.NET standards (e.g. does not require calling 'NextResult' on SELECT queries)
Works with ORM like Dapper, Linq2DB, Entity Framework Core etc.

Documentation for the library is available in repository Wiki
