The 1.5.0 release of the Go client came out on April 13, 2015 and is available for download here. This release features a number of new features, improvements and fixes.
New Features
- Introduces ClientPolicy.LimitConnectionsToQueueSize. If set to true, the client won’t attemp to create new connections to the node if the total number of pooled connections to the node is equal or more than the pool size. The client will retry to poll a connection from the queue until a timeout occures. If no timeout is set, it will only retry for ten times.
Improvements
- BREAKING CHANGE: Uses type aliases instead of structs in several XXXValue methods. This removes a memory allocation per Value usage. Since every Put operation uses at list one value object, this has the potential to improve application performance. Since the signature of several NewXXXValue methods have changed, this might break some existing code if you have used the value objects directly.
- Improved Logger so that it will accept a generalized Logger interface. Any Logger with a Printf(format string, values …interface{}) method can be used. Examples include Logrus.
- Improved Client.BatchGet() performance.
Fixes
- Bin names were ignored in BatchCommands.
- BatchCommandGet.parseRecord() returned wrong values when BinNames was empty but not nil.
