13. Keys simply binary values used to identify Objects.* Values
can be numbers, strings, objects, binaries, etc. Buckets used to
define a virtual namespace for storing Riak objects. Data Model
Riak stores data as a combination of keys and values in buckets

"Alpha2_s": "US, "Alpha3_s": "USA, "EnglishName_s": "United States,
"NumericCode_i": 840 } Riak offers both HTTP and Protocol Buffers
APIs. The following HTTP API example uses curl to retrieve a value
by key: Note: Protocol buffers are Google's language-neutral,
platform-neutral, extensible mechanism for serializing structured
data think XML, but smaller, faster, and simpler. Data Model

support both the HTTP and Protocol Buffer APIs: Basho Supported
