CqlSharp 0.30.0

CqlSharp is a high performance, asynchronous Cassandra CQL binary protocol client implementing the ADO.NET data provider interfaces.

     It's main features are:
     * The API implements the ADO.NET interfaces. If you are familiar with SqlConnection, SqlCommand, and SqlReader, you should be able to use CqlSharp with no difficulty.
     * CqlSharp is an implementation of the (new) CQL Binary Protocol and therefore requires Cassandra 1.2 and up
     * CqlSharp supports all the binary protocol v2 features: batching, paging, bound query variables, result schema caching, check-and-set (CAS) statements, and sasl-authentication
     * Supports fast mapping of objects to query parameters, or query results to objects. Mapping is tunable by decorating your classes via Table and Column attributes.
     * CqlSharp allows for partition/token aware routing of queries. This allows queries to be directly sent to the Cassandra nodes that are the 'owner' of that data.
     * Query timeouts and cancellation is supported
     * Query tracing is supported.
     * Provides an extendable logging infrastructure using MEF. Related log statements can be correlated through "Activity GUIDs"
     * CqlSharp supports Snappy compression of queries and responses
     * The API is predominately [asynchronous](https://msdn.microsoft.com/en-us/library/vstudio/hh191443.aspx), heavily relying on the System.Threading.Tasks namespace. Synchronous alternatives are available for convenience.
     * Configuration is done through connection strings. The simultaneous use of multiple Cassandra clusters is supported.
     * Most behavioral aspects of the CqlSharp are configurable: max number of connections, new connection threshold, discovery scope, max connection idle time, etc. etc.
     * Relative Node Discovery: given the 'seed' nodes in your connection string, CqlSharp may find other nodes for you: all nodes in your cluster, nodes in the same data center, or the nodes in the same rack
     * Load balanced connection management: you can give your queries a load 'factor' and the client will take that into account when picking connections to send queries over.
     * Queries will be automatically retried when connections or nodes fail.
     * Node monitoring: Node failure is automatically detected. Recovery checks occur using an exponential back-off algorithm
     * CqlSharp listens to Cassandra events for node up, new node and node removed messages such that Cluster changes are automatically incorporated

Release Notes

Version 0.30.0 - Binary Protocol V2 support

     * Allowing default database to be set via connectionstring, regardless of connectionstrategy in use
     * Sasl Authentication support. PasswordAuthenticator is supported out-of-the-box. Extendable via MEF by providing IAuthenticator and IAuthenticatorFactory implementations.
     * Batch support via CqlBatchTransaction. Assign the command to the CqlBatchTransaction and executes will be buffered. When CqlBatchTransaction is committed it will create and submit a batch statement.
     * Paging support. CqlCommand can be given a page size: when iterating over a query result, the data will be fetched in "chunks" of the given page size
     * Use of bound parameters with non-prepared queries
     * Support for Serial_Local for CompareAndSet (CAS) statements
     * Added CqlConnection.Shutdown methods to close all connections to Cassandra
     * Performance: when using Cql protocol v2, cached result metadata will be used, reducing network overhead
     * Performance: Prepare() better utilizes caching, less Task creation overhead
     * Fix: ChangeDatabase function uses correct use syntax
     * Fix: ConnectionStratagies are better aware of existing connections on startup.
