More details on the document API can be found in the github repo, tutorial and blog post.

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.

The Aerospike Document API provides such an API, using the CDT API. Below we demonstrate the way in which CRUD operations can be executed at arbitrary points within a JSON document using the API.

The object mapper library uses Java annotations to define the Aerospike semantics for the saving and loading behavior. Annotations are specified next to the definitions of a class, methods, and fields. The object mapper makes managing persistent data easier to implement, easier to understand, and less error prone. Check out the Java Object Mapper workshop and tutorial.

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.
