Hi 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.
http://riak.scalapenos.com/ 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 http API and currently it supports the following Riak features: - Fetch - Store - Delete - Secondary Indexes (2i) - Fetching exact matches - Fetching ranges - Storing with indexes - Getting/setting bucket properties - ping 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 RiakValue class 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 returnbody=true) - Automatic (de)serialization of Scala (case) classes using type classes - builtin spray-json (de)serializers - Automatic indexing of Scala (case) classes using type classes - Auto-retry of fetches and stores (a standard feature of the underlying spray-client library) The following Riak (http) API features are still missing and will follow soon: - Link walking - Map Reduce - Listing all keys in a bucket - Listing all buckets - Conditional fetch/store semantics (i.e. If-None-Match and If-Match for ETags and If-Modified-Since and If-Unmodified-Since for LastModified) - Node Status Check it out at: http://riak.scalapenos.com/ Cheers, Age
