About the C# driver
The C# Driver 1.0 for Apache Cassandra works exclusively with the Cassandra Query Language version 3 (CQL3) and Cassandra's new binary protocol which was introduced in Cassandra version 1.2.
The driver architecture is a layered one. At the bottom lies the driver core. This core, located in Cassandra.dll Assembly, handles everything related to the connections to a Cassandra cluster (for example, connection pool, discovering new nodes, etc.) and exposes a simple, relatively low-level API on top of which a higher level layer can be built.
The Linq2CQL module is built on top of the driver core and is located in Cassandra.Data.Linq.dll Assembly. It is a LINQ driver for Cassandra.
- connection pooling
- node discovery
- automatic failover
- load balancing
Queries can be executed synchronously or asynchronously, prepared statements are supported, and LINQ can be used to embed queries directly into C# code.
