Method Details

getChangeSchema

public org.apache.kafka.connect.data.Schema getChangeSchema()

serialize

public List<org.apache.kafka.connect.data.Struct> serialize(TableChanges tableChanges)

Specified by:

serialize in interface TableChanges.TableChangesSerializer<List<org.apache.kafka.connect.data.Struct>>
