How do you perform aggregation via UDF for Document API queries? Is it possible? Possibly to get multiple values? Groupbykey and similar?
Hi @Stephen_Johnston, welcome to the community!
The Document API is for a single record with JSONPath queries supporting some aggregate functions to invoke at the end of the path. There is not a way to combine JSONPath with Lua aggregates.
Here are some great resources on the Document API:
The Aerospike Map API could potentially be useful as a Map in Aerospike is an internal representation of a JSON document. You could run a filter expression query with a no-bins policy to get the keys that match, then run a batch operation on them using the Map API.
Or you could loop through the records with the Document API.
