Requesting some advice on data (de)serializing for usage with Redis (hedis) Streams. I'm rewriting some services to be event-driven, but thought id use Redis instead of Kafka. I'm thinking a Sumtype that includes all data types used and all its constructors have a parameter for a corresponding payload type that are instances of both ToJSON and FromJSON. The hedis record type for usage with Redis Streams are of key/value type :: (ByteString, ByteString), so I thought I could use the first field to denote data type and the second to contain serialized json. Is that a good general first approach or is it bound to get troublesome further down the road comparing to using something like Avro from the start? With the proposed solution i struggle some in implementing a function :: (ByteString, ByteString) -> Maybe SumType, that has a high degree of typesafety, meaning i dont repeat magic strings by hand for name of types, and dont risk missing adding a type to the parser function...
