Version 0.32.0 - Decimal support and Fixes

  • Support for decimal types
  • TimeGuid generation rewritten in order to guarantee uniqueness when many TimeGuids are generated within a short timeframe.

Version 0.31.0 - Linq-2-Cql

  • Adjustments to support Linq2Cql in CqlSharp.Linq package
  • Making ObjectAccessor public accessible
  • Introducing CqlKey and CqlIndex attributes

Version 0.30.2 - Deadlock removal

  • Fix: Adding two missing ConfigureAwait statements avoiding deadlock in MVC projects

Version 0.30.1 - Node address fallback

  • Fallback to listen-address during discovery when rpc-address is 0.0.0.0. Issue #20
  • Performance: Removing some boxing of structs during deserialization

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.

Version 0.20.1 - Oops

  • Critical bug fix: connection idle bug due to comparison of datetimes in different timezones, Issue #15

Version 0.20.0 - ADO.NET implementation

  • CqlSharp now implements the ADO.NET interfaces (this is a breaking change!), using the System.Data.Common classes
  • Introduced QueryResult property on CqlCommand to expose Cassandra result information for non-Queries
  • Parameters for prepared queries will be automatically generated when no paramaters are set beforehand
  • ClusterConfig replaced by CqlConnectionStringBuilder (and moved to root namespace)
  • Query cancellation now supported
  • Database can be changed from default to something else per CqlConnection when Exclusive strategy is used
  • Some preparation to make ConnectionStrategy extendable like logging
  • Getting and logging more info on Cassandra cluster like name, release, cqlversion, etc.

Version 0.14.1 - Bug fixes (not released)

  • Making short values unsigned shorts as depicted in Cql binary protocol spec.
  • Added few missing ConfigureAwaits
  • Cleanup of code
  • Faster Random Strategy Logic

Version 0.14.0 - Need for Speed

  • ObjectMapping performance improvement: Using compiled expressions to set and get object properties and fields
  • Snappy compression support
  • Removed ParallelConnections option, corresponding behavior now depends on connection selection strategy
  • Improved memory management (more byte[] reuse, different array sizes, faster pool)
  • Faster Balanced Strategy logic

Version 0.13.0 - Logging and Contexts

  • ConfigureAwait on all awaits to avoid issues with synchronization contexts
  • Logging! Extendable via MEF by simply implementing and co-deploying ILoggerFactory and ILogger implementations
  • Small bug fixes

Version 0.12.0 - Null values

  • Support/fix for null values
  • Support for Nullable types
  • Addition of Max Query Retry configuration parameter
  • Performance improvements (less async, less spinlock where lock is wanted)
  • Fixing some nasty race conditions

Version 0.11.0 - Cluster changes

  • Several bug fixes
  • CqlSharp now listens to cluster events like Node Up/Down/Add/Remove. Nodes are added and removed while the application is running.

Version 0.10.0 - Partition Aware

  • Added PartitionKey, PartitionAware Connection Strategy that selects a connection based on the PartitionKey set on a CqlCommand.
  • Removed QueryOptions class, options can now be set directly on CqlCommand objects.
  • Bug fix on short serialization
  • Removed a few race-conditions
  • Added varint support

Version 0.9.0 - Let's go!

  • Initial public release
