riak_client 0.6.1

Riak Dart client #

Riak database client, written in Dart.

Features #

Available Riak functionality:

  • fetch, store and delete objects (with vclock, vtag and last modified preconditions)
  • store and query secondary index
  • get and set bucket properties
  • resolve conflicts if parallel writes produce siblings
  • counters (fetch, increment/decrement)

Dart client design goals:

  • Meaningful wrapper objects
  • Immutable structures (exception: JSON content, but changes won't be pushed)

Roadmap #


  • map-reduce support
  • link-walking support
  • list-resources support


  • protobuf client implementation
  • mixed client (protobuf / http, based on the request)
  • search support


  • mock backend for testing (in-memory and filesystem)
  • configurable retry-on-failure
  • robust stream handling (e.g. what to do on backend failure, re-start?)
  • non-buffered HTTP response processing
  • pooling client (simple round-robin)


  • stable API
  • pool monitoring and stats

The order might vary, depending on the contributor's requirements. If you would like to add something, contact us (see AUTHORS or pubspec file).
