Connect. Includes the following:

ExtractTopic: Extract data from a message, and use it as
the topic name.

a string), or use a field from a map or struct.
Use the concrete transformation type designed for the
record key
(io.confluent.connect.transforms.ExtractTopic$Key) or
( io.confluent.connect.transforms.ExtractTopic$Value).

Drop: Drop either the key or value from a message,
setting it to null.
Use the concrete transformation type designed for the record key
(io.confluent.connect.transforms.Drop$Key) or value
