CQLSharp - An ADO.NET Data Provider for Cassandra

CqlDataReader bug fix

• Fix: make sure latest value is deserialized in Current property of CqlDataReader{T}
• Fix: remove redundant logging when PartitionAwareStrategy is used

Array support and Node restart fixes

• Fix: Solve issue where CqlSharp can't reconnect when a Cassandra node is restarted
• Improved type system: support for arrays in value conversion (from/to list types)
• adding IsEqual to CqlColumnInfo to compare column values of two entities

CQLSharp - An ADO.NET Data Provider for Cassandra

• Solves issue with connection to 2.0 and 1.x clusters when MaxQueryRetries=0
• Retries CqlConnection.Open up to MaxQueryRetries + 1, when opening connections to the cluster fails

CQLSharp - An ADO.NET Data Provider for Cassandra

• Implements binary protocol v3: more queries per connection, timestamp property, UDT and Tuple types, larger collections.
• Rewrite of type system, CqlType is no longer an enum but a class with subclasses for every Cassandra type.
• Previous CqlType enum is now called CqlTypeCode.
• Primitive Cql types can be accessed through CqlType.* static properties. Others can be constructed from .NET class, type string, or TypeCode + parameter via the CqlType.CreateType overloads.
• CqlParameter no longer accepts different CqlTypeCodes, but requires a single CqlType
• Added high performance and extremely flexible type conversion that prevents boxing, and even converts collection types (e.g. hashset{int} to list{long})
• Removed explicit references to collection key and value types. They are not used separate from the corresponding CqlTypes anymore
• CqlDataReader.GetDataTypeName(int i) now returns full string representation of the Cassandra type (e.g. map{varchar, int=""})
• CqlDataReader.GetFieldCqlType added that returns the CqlType used for the given field
• Removed a lot of boxing/unboxing of primitive types during serialization/deserialization
• Implemented DbDataReader.GetFieldValue{T}(int i)
• Supports User Defined Types. Annotate your class with CqlUserType and CqlColumn to have it correctly mapped to a Cassandra User Defined Type
• Guesses protocol version from release_version shortening connection setup times for older clusters

CQLSharp - An ADO.NET Data Provider for Cassandra

• Many changes to have synchronous API really execute synchronously, it is no longer a sync-over-async wrapper
• Improved exception generation in case of query cancellation or timeout
• Logging cancelled queries
• Replacing old test app with a new performance test app
• added NLog as seperate logging package
• Fix: Adding LocalOne consistency level

Fixes and Improved Aliveness Checking of Cassandra Nodes

• Fixed bug that hampered exponential backoff
• Succesfull connection to a node must be made before it is marked as up again, keeping it out-of-scope of connection strategies until proven up.
• Fixing issue where multiple node UP notifications are received in a short time
• Clearing prepared query ids, forcing queries to be reprepared when node is marked down
• Making sure that at least a single query attempt is done when MaxRetryCount setting is set to 0
• MEF fix: now using correct directories for loading extensions

CQLSharp - An ADO.NET Data Provider for Cassandra

Fixes, fixes and fixes. Added support for TraceLogger

ADO.NET Data Provider for Cassandra

• Improved state management of transactions
• Adding Reset to CqlBatchTransaction, allowing reuse of transaction objects
• Adding CqlError class, to expose Cql error details (including trace ids) as LastQueryResult on CqlCommand
• Fixing issue where nill guids were inserted as null values
• Adding TimeGuid.Default to get a nill guid with time version flags set.
• Fixing race condition issues when using prepared queries in a transaction
