The CDT API contains all the primitives required to build the Aerospike Document API using the well known JSONPath standard which is modeled on the W3C XPath standard for XML. Like XPath, JSONPath supports CRUD operations via filesystem-like navigation syntax.
JSONPath queries enable developers to query documents stored in Aerospike bins using JSONPath operators, functions and filters. Developers provide a JSONPath query to Aerospike, specifying the relevant record key and the bin name that stores the document, and they retrieve the data matching the query. For more information on JSONPath queries, please refer to this blog.
