java-object-mapper
The Java Object Mapper is a simple, light-weight framework used to map POJOs to the Aerospike database. Using simple annotations or a configuration YAML file to describe how to map the data to Aerospike, the project takes the tedium out of mapping the data through the powerful, low level interface.

The tuple form eliminates redundant storage of keys as in Map. Objects stored as tuples must use Unordered (or more precisely, insertion- or application-ordered) List, which preserves the tuple order irrespective of the field values. Application must manage the object schema, that is, how the tuple order matches the object fields, and also schema evolution. The Object Mapper library can be used to manage these aspects transparently.
Document API library to store a JSON document to, and retrieve it from, a Map bin. The library also supports JSONPath queries on a stored document. Check out the interactive tutorial.
