Provide a way to support camel type converters and/or integrating them in kafka connect `key.converter` and `value.converter`.
comment 1 @omarsmak: Hello @valdar , what is the plan for this issue? If no one is working on it currently, I can work on it as well
comment 2 @valdar : Sure @omarsmak I will be more busy with #4 in near future.
I would appreciate if you can outline your idea before starting to code, so we can be sure we are on the same page; I admit the issue's description is not the most detailed one... they were initially made as a self note/brain dump...
comment 4 @omarsmak Sure, one option I could think of from the top of my head is, we could try to utilize Camel type converter registry somehow, we can use this to serialize the data if we have the info about the data from -> to types. Will need to experiment this though
comment 5 @omarsmak : Actually it depends, the question what do we want to achieve here, do we want to convert the data from/to byte before sending it to kafka, or do we want just to transform the data? The way I can think about it is like this:
* Kafka Connect Transformation can work with camel type converters
* Kafka Connect Converter can work with camel data format
However let's take an example, let's see we have this S3 component that includes a type converter that convert from `S3ObjectInputStream` to `byte` and vice versa, if that is the case, then it would be better suited as Kafka Connect converter, isn't?
comment 6 @omarsmak : @valdar I need to dump my thoughts before I forget :D:
Probably you are right, an SMT wrapper will be suitable for this. We can use Camel TypeConverter registry that can be obtained via `DefaultCamelContext`. What I can purpose is the following:
* We add a `TypeConverterTransform` SMT class, which is a wrapper around Camel TypeConverter registry, since we don't have enough information about the types that we need convert from -> to, I suggest the user will need to add this into the config, then in this wrapper, we will add the schema info in the `Struct` object and convert the value accordingly per the user data type configs.
* Once we have the above SMT, we can as well use it as a 'Default' converter into a Kafka Connect converter wrapper, to be used as Kafka Connect converter, before sending the data to Kafka as `byte`.
Please feel free to discuss :)
