>
> Right now users must provide two separate classes for serializers and 
> deserializers, respectively.  This means the current API functions have at 
> least 2 * numberOfTypes parameters.
> *Example (current, bad): "foo(..., longSerializer, longDeserializer)".*
> Because the serde aspect of the API is already one of the biggest UX issues, 
> we should unify the serde functionality into a single serde class, i.e. one 
> class that provides both serialization and deserialization functionality.  
> This will reduce the number of required serde parameters in the API by 50%.
> *Example (suggested, better): "foo(..., longSerializerDeserializer)"*. 
> * Note: This parameter name is horrible and only used to highlight the 
> difference to the "current" example above.
> We also want to 1) add a pairing function for each operator that does not 
> require serialization and 2) add a default serde in the configs to make these 
> not required configs.
