Preferred request handler interface to implement AWS Lambda












0















I am writing an AWS lambda in Java. Lambda provides two interfaces to implement the request handler.




  1. RequestHandler - Uses lambda’s serialization for converting input request to InputPojo and vice versa for output.

  2. RequestStreamHandler – Implementor writes serialization-deserialization logic on input/output stream.


I could not find documentation on serialization behavior of Lambda. I am not sure of questions like




  • Will the serde ignore unknown properties?

  • Will the serde ignore null
    fields?

  • How to i specify names of json fields

  • Can the above behavior change in future?


I wanted to use Jackson annotations to have more control on this. But the documentation specifically states
“You shouldn't rely on any other features of serialization frameworks such as annotations..“
So I am planning to use the second interface.



Before proceeding, given all above, want to check the recommended interface to use? which to use when?



Thanks
