After three months of hacking, I’m proud to announce a new Riak Scala client library based on Akka and Spray and simply called riak-scala-client. It aims to be easy to use, non-blocking, and fast, in that order.
This is the first public release but I’ve been testing it on a large project since January and it was time to let other people kick the tires and tell me what I did wrong (or right).
The client is purely based on the Riak http API and currently it supports the following Riak features:
- Secondary Indexes (2i)
- Getting/setting bucket properties
Other features include:
- Completely non-blocking thanks to Scala 2.10 Futures, Akka, and Spray
- Transparent integration with Akka projects through an Akka extension
- An untyped
RiakValueclass for interacting with raw Riak values and their associated meta data (vclock, etag, content type, last modified time, indexes, etc.)
- A typed
RiakMeta\[T\]class for interacting with deserialized values while retaining their associated meta data (vclock, etag, content type, last modified time, indexes, etc.)
- Customizable conflict resolution on all fetches (and stores when
- Automatic (de)serialization of Scala (case) classes using type classes
- Builtin default spray-json (de)serializers
- Customizable indexing of Scala (case) classes using type classes
- Auto-retry of fetches and stores (a standard feature of the underlying spray-client library)
Missing features such as link walking and Map-Reduce will be implemented as soon as possible.
