 ## Supported serialization formats
 The connector does not do data deserialization on its own. It relies on Kafka Connect converters to deserialize data. It's been tested predominantly with JSON, but it should work with any converter, including Avro. Converters can be configured using `key.converter` and `value.converter` options, see the table above.
