We want to store function results calculated by users and which return an array of structs as a Result object to be reviewed later. The List of structs is solely related to that object and may contain a lot of values (key-value pairs for plotting purposes) which is why we would like to avoid full indexing with primary key creation etc. to avoid a too large ontology volume while still having granular permissions on the results for sharing the Results with selected people down the road.
Also, being able to store function results in a list of structs would hopefully speeds up the fetching of the values since they are directly linked to a single primary key.
This is a related issue: Support struct variables in Action Types - Propose an Improvement - Palantir Developer Community
The documentation states that this is currently not possible. Is there maybe a timeline / expectation for this? maybe it is already on the roadmap?
