DB 패스워드를 암호화하기 위해 key-store를 생성하게 되는데여기에서도 key-store의 패스워드가 yml 설정파일에 존재하게 되는 것으로 이해했습니다.key-store의 패스워드는 암호화 하지 않아도 되는건지 헷갈려서 질문드립니다.만약 암호화가 필요하다면 DB 패스워드를 암호화 하기 위한 key-store의 패스워드를 암호화 하기위한 key-store..... 이런식으로 무한루프가 돌 것 같은데 실무 환경에서는 어떻게 사용하고 있는지 궁금합니다.

eureka.clinet.fetch-registry : true 의미가 클라이언트가 유레카 서버를 통해 다른 서비스 정보를 얻기을 수 있다고 알고있습니다. 여기서 궁금한 점이 있는데인스턴스가 다른 인스턴스의 정보가 필요한 이유가 자신이 받은 요청이 다른 인스턴스의 서비스가 필요할 떄가 있어서 그런 건가요??

환경 문제로 인하여 Oracle Cloud Vm 서버 3개를 별도로 띄어 실습 환경을 구성하였습니다.문제는 Hbase 에 적재가 안된다는 것입니다.일단 환경구성에서 모든 모듈들을 latest기준으로 구성을하여서 강의내용과는 다를수가 있을듯한데요.데이터 수집 적재 파이프라인 에서 kafka 까지 들어오는것은 확인하였으나 storm 토폴로지에서 kafkaspout 에서 반응이 없는것으로 봤을때 bigdata.smartcar.storm-1.0.jar 에서 바라보는 어떠한 환경설정정보가 맞지 않아 생긴문제로 생각이되어 소스를 봤으나 별다르게 찾은것은 없습니다.zookeeper cli 에서는 kafa producer 노드가 있는것은 확인했고 SmartCar-Topic 노드는 없는것으로 확인했습니다.혹시 놓친부분이 있을까요?

안녕하세요. 저같은사람이 없기를 바라며 오류 해결법을 올립니다...환경은 23년 기준 스프링부트. 스프링클라우드 모두 최신버전입니다. (대신 강의처럼 maven이 아닌 gradle입니다)23년 4월중순부터 강의를 잘 따라하다가 빌드후 실행하면 user-service에서 에러가 나는겁니다.openfeign 관련 에러였습니다.  org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with

Users Microservice - JPA 수강중입니다.실습 따라서 작성하고 있는데 오류가 나는데 잘 모르겠습니다.UserServiceImpl 에서ModelMapper mapper = new ModelMapper();mapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);UserEntity userEntity = mapper.map(userDto, UserEntity.class);userEntity.setEncryptedPwd("encrypted_password");여기까지 값이 잘 찍히다가 userRepository.save(userEntity); <-- 여기서 오류가 납니다. 2023-04-24T21:55:59.923+09:00 ERROR 3608 --- [o-auto-1-exec-6]

안녕하세요, 빅디님!차근차근 따라하려고 하는데.. 한 강 한강 막히고 있습니다.. 하둡과 주키퍼 명령 사용해보기 강의보며 실습중인데,명령어가 먹히지 않습니다.. 연결이 안되는 에러로 보여서 클라우데라 접속하려고 했더니 클라우데라도 접속이 안됩니다. 빅데이터 클러스터 구성 4 강의 까지는 다 따라한 상태입니다.  클라우데라 접속해서 하둡과 주키퍼 설치까지 완료하였고 일주일? 지난 후 다시 접속해서 그 이후 과정 따라하려고 하니 접속에러 & 연결에러가 뜨고 있습니다............ ㅠㅠ 막힘없이 쭉쭉 나가고 싶은데 ,, 대체 무슨문제일까요 ? 저 같은 에러를 경험하신 분이 있을까 싶어 이전 질문글을 살펴봤는데 파일럿 PC의 용량이 존재해야 한다고 하여 정리도 하고, 실행했습니다.많이 사용하긴 했지만 212GB가 남아있는 상황입니다.. 실습 쭉 따라하고 싶습니다..빅디님.....ㅠ_ㅠ!! ++로그 확인이상 없음.(참고로 모바텀을 사용하고 있어서 파일질라는 사용안하고 모바텀으로 바로 Sample.txt -> /home/bigdata 로 올렸습니다. 파일 잘 올라온 것 확인했습니다.)  감사합니다. 

터미널에서 9003 포트 실행할 때, 9001 포트가 중복된다고 발생하는 경우는 명령어가 잘못되서 그렇습니다. 강의랑 조금 다르네요 ' ' 해당 부분을 확인해주세요. mvn spring-boot:run '-Dspring-boot.run.jvmArguments=-Dserver.port=9003'

안녕하세요.현재 k8s 환경에서 롤링 업데이트를 통해 팟을 배포하는 방식을 채택하여 사용중에 있습니다.메시지 컨슈밍 퍼포먼스를 줄여주기 위해 리밸런싱 시간을 줄여주는게 굉장히 중요하다는 생각이 드는데요.강의를 보다보니 Static membership과 Cooperative sticky 2가지 방식이 이에 적합한 것 같아 보입니다.실제 프로덕션 레벨에서는 어떠한 방식을 사용하는지 궁금합니다!

2가지 궁금한게 있는데요첫번째는 카프카 커넥트와 직접 코드로 구현되는 컨슈머 중 하나를 선택해야 할 때 어떤 기준으로 선택하는 것이 좋을까요?커넥트 장점을 보면 추측은 가능하지만 경험이 없으니 실무에서 어떨 때는 커넥트, 어떨 때는 컨슈머 직접 구현을 선택할 수 있는지(이건 경험 꽤 많아요) 기준이 궁금합니다 두번재는 자동으로 토픽 생성시에 시스템 종료하면 어떤게 문제가 될까요?그레이스 풀 셧다운 관련인지 어떤 문제가 생기는지 궁금합니다 감사합니다.

안녕하세요 자주 질문을 드리게 되어 죄송합니다.데이터가 이동하면서 아래와 같은 작업이 이루어지는 것을 강의를 통해 이해했습니다.source connector --> kafka : 직렬화kafka --> sink connector : 역직렬화 그렇다면 혹시 java 를 사용하여 kafka로 바로 데이터를 적재 할 경우 sink connector로 데이터를 보낼 수가 있을까요?? 역직렬화 작업이 안될 것으로 보여서 가능한지 질문 드립니다.가능하지 않다면 java로 kafka를 보낼 때 직렬화 작업이 된 상태로 보내야 할까요??

K8S나 Docker Swarm 없이 2대 이상의 Host PC에 Multi Cluster를 구성할 수 있을까요?혹시 2대의 PC에 각각 Docker를 설치하고, 여기에 분산되서 올라간 Container들을 하나의 Network으로 묶는것이 가능한가 해서요.방법이 있으면 알고 싶습니다

안녕하세요. 강의를 듣던 중 에러가 발생하여 질문드립니다. order service에 마리아디비 연동시 에러가 발생합니다.(pom.xml 파일에 마리아디비 의존성 추가 했습니다)order-service: application.ymlserver: port: 0 spring: application: name: order-service h2: console:

안녕하세요!제가 강의를 다 듣고 난 뒤 추가로 공부를 해볼 생각으로catalog-service 에서 example-catalog-topic 를 받은 뒤상품의 개수를 파악 후 재고 유무의 따라 order-service 에주문 상태를 전달 해주는 example-order-topic 를 만들어 구독 중인 order-service 에서example-order-topic 에서 전달 받은 주문 상태를 업데이트 하는 로직을 구현하려고 했습니다.로컬에서 order-service 와 catalog-service 의 consumer groupId 를 consumerGroupId 로 통일해서 사용 했을 때는 괜찮았으나, docker 에 올리니 example-order-topic 이 생성은 됐으나 구독 및 전달이 되지 않더라구요.... 혹시나 해서 order-service 의 consumer groupId 를 consumerGroupId2 로 변경하여 docker 에 올리니 정상 작동이 됩니다. 혹시 각각의 service 는 groupId 를 다르게 해주어야 할까요??

안녕하세요! 제가 카프카 컨슈머 애플리케이션을 개발해서aws 서버에 올려놓고 계속 컨슈밍을 할 예정입니다.강의에서 컨슈머의 안전한 종료 파트를 듣고 질문이 생겨 글을 남깁니다.이렇게 서버에 계속 올려놓고 컨슈밍을 받아야할때 컨슈머의 종료가 필요한가요?만약 필요하다면 종료된 컨슈머는 어떻게 재실행이 되는 건지 여쭤볼 수 있을까요? 일단 저는 스프링기반 카프카 컨슈머를 개발하였고 Runnable 인터페이스로 run() 메서드로 서버가 실행되면 바로 컨슈머가 실행되게 개발해놓은 상태입니다.   저의 코드입니다.@PostConstruct public void startConsuming() { Thread consumerThread = new Thread(new Consumer()); consumerThread.start(); } private class Consumer implements Runnable { private final Logger logger = LoggerFactory.getLogger(Consumer.class); private final static String TOPIC_NAME = ""; private final static String BOOTSTRAP_SERVERS = ""; private final static String GROUP_ID = ""; public void run() { try { Properties configs = new Properties(); configs.put(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS); configs.put(ConsumerConfig.GROUP_ID_CONFIG, GROUP_ID); configs.put(ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName()); configs.put(ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getName()); // 구독 중인 주제 파티션에서 사용 가능한 가장 빠른 오프셋부터 읽기 configs.put(ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest"); configs.put(ConsumerConfig.SESSION_TIMEOUT_MS_CONFIG, "30000"); configs.put(ConsumerConfig.HEARTBEAT_INTERVAL_MS_CONFIG, "5000"); configs.put(ConsumerConfig.MAX_POLL_INTERVAL_MS_CONFIG, "300000"); KafkaConsumer<String, String> consumer = new KafkaConsumer<>(configs); consumer.subscribe(Arrays.asList(TOPIC_NAME)); while (true) { ConsumerRecords<String, String> records = consumer.poll(Duration.ofSeconds(1)); for (ConsumerRecord<String, String> record : records) { logger.info("record: {}", record); // 받은 메세지 String value = record.value(); // commit the offset consumer.commitSync(Collections.singletonMap( new TopicPartition(record.topic(), record.partition()), new OffsetAndMetadata(record.offset() + 1))); } } } catch (Exception e) { logger.error("Error occurred while consuming messages", e); } } }

mySQL과 카프카 연결로 강의해주셨는데요아직 일부만 수강한 상태입니다.debezium이 차후에는 싱크 커넥터들을 데이터베이스 상관없이 지원할거같기도해서mySQL말고도 강의를 참고해서오라클 SQL, MSSQL에도 카프카를 연결하고 싶습니다.이때 접근방향이나 차이점등이 궁금한데 혹시 경험해보신적있다면 조언받고 싶습니다. 감사합니다 

제가 카프카에 대한 구조와 사용법을 이해하지 못해서 학습 재미가 떨어지는데요.카프카를 이렇게 써야 하는지를 맞는지가 궁금합니다. 많은 영상을 봤지만서도 사용법이 잘 이해가 안되서 질문드립니다

안녕하세요 전에도 질문을 올렸었는데 답변 주신 대로 했더니 잘 해결 되었습니다.감사합니다.전에 올린 질문 중 답변해주신 내용이 oracle connector는 하나의 source connector만 생성하면 된다고 하셨는데요.하나의 source connector로 구성 후 테이블을 추가하려고 하는데 추가할 경우에는connector를 다시 생성해야 할까요?아래의 명령어로 update 후 재기동을 해봤으나 추가한 테이블에 대한 topic이 생성 되지 않습니다.http PUT http://localhost:8083/connectors/ora_source_connector/config @ora_source_connector_test.json http POST http://localhost:8083/connectors/ora_source_connector/restart json 내용{"connector.class" : "io.debezium.connector.oracle.OracleConnector","db_type":"oracle","tasks.max" : "1","database.server.name" : "source_connector_01","database.user" : "xx","database.password" : "xx","database.url": "jdbc:oracle:thin:@xx","database.dbname" : "xx","database.out.server.name":"ora_source_out","schema.history.internal.kafka.bootstrap.servers" : "xx:9092","schema.history.internal.kafka.topic": "ora_source_history","schema.include.list": "xx","include.schema.changes": "true","database.connection.adapter": "logminer","topic.prefix": "ORA_SOURCE","schema.include.list": "xx","table.include.list":"xx.AF_CLAIM , xx.AF_CS_MGMT , xx.AF_BRAND","include.schema.changes": "true","auto.evolve": "true","time.precision.mode": "connect","key.converter": "io.confluent.connect.avro.AvroConverter","value.converter": "io.confluent.connect.avro.AvroConverter","key.converter.schema.registry.url": "http://localhost:8081","value.converter.schema.registry.url": "http://localhost:8081","snapshot.mode" : "initial","tombstones.on.delete": "true","transforms": "rename_topic","transforms.rename_topic.type" : "org.apache.kafka.connect.transforms.RegexRouter","transforms.rename_topic.regex" : "ORA_SOURCE(.*)","transforms.rename_topic.replacement" : "source_$1","transforms": "unwrap","transforms.unwrap.type": "io.debezium.transforms.ExtractNewRecordState","transforms.unwrap.drop.tombstones": "false"}
