@rhauch Thank you for your review. I appreciate it. I'm reading through your comments and will solve it. :)

@rhauch Could you tell me what different between INT8, INT16, INT32, etc. (data range) in Kafka Schema. Any reference to SchemaField description?

I found this but not detail anymore.

[rhauch]

@toanalien Kafka Connect's schema types are the same as the Java types, and that matches the CrateDB documentation that says:

All types have the same ranges as corresponding Java types.

I think your latest commits have it right.
