- Encoding the serialization in the schema for Decimal LogicalType. This is good because it means that the deserializer will be able to decode based on the schema and one converter can handle different topics encoded differently as long as the schema is in line. The problem is that this is specific to only JSON and changing the LogicalType is not the right place.
- Automatically detecting the serialization format. While it is possible to automatically differentiate NUMERIC from TEXT and BINARY, it is not always possible to differentiate between TEXT from BINARY. Take, for example, the string "12" - this is both a valid decimal (12) and a valid hex string which represents a decimal (1.8).
