Riak Interface for Pharo Smalltalk

I have published the first beta version of a Pharo Smalltalk interface to Basho’s key-value database “Riak”. The interface uses the REST API of Riak.

The current version (0.2) supports:

• Storing an object (JSON / text / blobs) at a key (PUT operation)
• Getting object at a key (GET operation)
• Deleting a key
• List all buckets
• List all keys in a bucket

Here are the planned features that will be added:

• Avoid the need to specify data type on put operation
• Error handling
• Class that represents a key
• Handling of “sibling” objects
• Get meta-information about database
• Map-Reduce support
• Streaming support

In a Pharo 1.1.1 image, use the following script to load the Riak interface:

MCHttpRepository
  location: 'http://www.squeaksource.com/EpigentRiakInterface'
  user: ''
  password: ''.

Gofer new
    squeaksource: 'EpigentRiakInterface';
    package: 'ConfigurationOfEpigentRiakInterface';
    load.

((Smalltalk at: #ConfigurationOfEpigentRiakInterface) project version: '0.2') load.

To run tests, set up a Riak database at a host named riaktest and execute tests in class EpigentRiakRestConnectionTest.
