mongodb-source-connectの使用中に "$ ChangeStreamステージがレプリカセットでのみサポートされています"エラー "
明けましておめでとう
Kafka-mongodb-source-connectを実行している間にエラーに直面していたので、私は実行しようとしていましたconnect-standaloneconnect-avro-standalone.propertiesと - MongoSourceConnector.properties MongoDBに書き込まれた接続データをkafkaトピックに接続する。
その進歩を試みながら私はこのエラーに直面し、私はここに書いているので、私は答えを見つけることができませんでした。
これが私がやりたいことです
