커넥션 풀을 통해 미리 커넥션을 생성하고커넥션을 쓰고 난 뒤 커넥션을 close 하지 않고 다시 반환 해서 재사용 한다라고 배웠습니다. 강의 내용과는 무관 할지 모르겠지만만약 동시 사용자가 엄청 많지 않다고 가정했을 때현재 사진처럼 커넥션이 4개 (conn0~4)까지 생성됐다고 한다면 conn0만 계속 사용 될텐데요.한 커넥션만 사용 되는 게 나중에 문제가 생길 수 도 있나요?

(예/아니오)[질문 내용]안녕하세요.카운트 쿼리 분리 부분을 듣는 도중에 카운트 쿼리에 LEFT JOIN이 사용되는 결과를 확인하기 위해 다음처럼 코드를 작성하였습니다.public interface MemberRepository extends JpaRepository<Member, Long> { @Query(value = "select m from Member m left join m.team t") Page<Member> findByAge(int age, Pageable pageable); ... } @Test public void paging() throws Exception { //given memberRepository.save(new Member("member1", 10)); memberRepository.save(new Member("member2", 10)); memberRepository.save(new Member("member3", 10)); memberRepository.save(new Member("member4", 10)); memberRepository.save(new Member("member5", 10)); //when PageRequest pageRequest = PageRequest.of(0, 3, Sort.by(Sort.Direction.ASC, "username")); Page<Member> page = memberRepository.findByAge(10, pageRequest); //then List<Member> content = page.getContent(); assertThat(content.size()).isEqualTo(3); assertThat(page.getTotalElements()).isEqualTo(5); assertThat(page.getNumber()).isEqualTo(0); assertThat(page.getTotalPages()).isEqualTo(2); assertThat(page.isFirst()).isTrue(); assertThat(page.hasNext()).isTrue(); }그런데 결과는 강의와는 달리 카운트 쿼리에 LEFT JOIN 이 사용되지 않았고, 심지어 JPQL select m from Member m left join m.team t 을 @Query에 작성했음에도 조회 쿼리도 LEFT JOIN을 사용하지 않은 것을 확인했습니다.이후 스프링 부트 3 이하 버전에서 동일한 코드로 실행해보니 강의와 동일한 결과를 얻을 수 있었습니다.스프링 부트 3 부터 적용된 스프링 데이터 JPA 에서는 이러한 부분의 최적화를 자동으로 제공하는 것일까요?

public void buy(String ticketName) throws InterruptedException { RLock lock = redissonClient.getLock(ticketName); try { boolean available = lock.tryLock(5, 1, TimeUnit.SECONDS); if (!available) { return; } ticketServiceWithRedisRedissonClientLock.buy(ticketName); } finally { if (lock.isLocked() && lock.isHeldByCurrentThread()) { lock.unlock(); } } }이 구조에서 tryLock에 대해서 5초동안 Lock 획득을 위해서 대기하고 Lock을 1초동안 점유하고 release하는 형식으로 알고있는데 만약에 쓰레드가 5초 동안 대기를 하더라도 최종적으로 Lock을 얻지 못한다면 return이 됨으로써 buy로직으로 못들어가는거 아닌가요?? 만약에 반드시 Lock을 얻고 buy로 들어가야만 하는 경우 Lock 재획득에 대한 로직을 따로 구현해야 하는건가요. 아니면 tryLock의 재시도에 대해서 제가 모르는 부분이 있는건가요?? public void buy(String ticketName) throws InterruptedException { final RLock lock = redissonClient.getLock(ticketName); final int maxRetryCount = 10; final int retryIntervalMillis = 1000; try { int retryCount = 0; boolean lockAcquired = lock.tryLock(5, 1, TimeUnit.SECONDS); while (!lockAcquired && retryCount < maxRetryCount) { log.info( "--> Thread [{}] Redis Distributed Lock (Redisson Client) 획득 대기", Thread.currentThread().getName() ); Thread.sleep(retryIntervalMillis); lockAcquired = lock.tryLock(5, 1, TimeUnit.SECONDS); retryCount++; } if (!lockAcquired) { log.info( "--> Thread [{}] Redis Distributed Lock (Redisson Client) 획득 실패", Thread.currentThread().getName() ); return; } ticketServiceWithRedisRedissonClientLock.buy(ticketName); } finally { if (lock.isLocked() && lock.isHeldByCurrentThread()) { lock.unlock(); } } }이런 방식으로 최대 재시도 횟수와 재시도 간 간격을 통해서 waitTime동안 Lock을 못얻을 경우 Lock자체를 다시 얻는 방식을 구현해보았고 waitTime=1, unit=ms로 변경하고 테스트했을 경우 정상적으로 retry가 됨을 확인했습니다. 이런 구조가 최선일까요??아니면 더 나은 방식이 있을까요? 

우선 저는 다음과 같이 MultipartFile을 받도록 작성했습니다.@RequestParam MultipartFile attachFile그리고 attachFile에 마우스를 대보았더니 다음과 같이 뜹니다.위처럼 @NotNull 이라는 annotation이 들어간 것을 확인할 수 있었습니다. 하지만 이 @NotNull이 javax.validation 것인지는 알 수가 없었습니다. 또한 @RequestParam의 required의 default가 true라서 그런가 싶어서 false로 지정해도 @NotNull은 사라지지 않았습니다.Null 인 경우는 파일을 선택하지 않았을때 밖에 생각이 안드는데요. 이때 당연하겠지만 오류 페이지로 넘어가게됩니다.저 @NotNull의 정체가 무엇인지 알고 싶습니다.
