# MongoDB Nanosecond Precision POC
|
||||||
|
|
||||||
|
> 작성일: 2026-01-21
|
||||||
|
|
||||||
|
## 개요
|
||||||
|
|
||||||
|
MongoDB BSON Date는 millisecond 정밀도만 지원하므로, nanosecond 정밀도를 보존하기 위한 POC 구현.
|
||||||
|
|
||||||
|
## 최종 저장 형식
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
// MongoDB Document
|
||||||
|
{
|
||||||
|
"_id": "...",
|
||||||
|
"eventId": "event-001",
|
||||||
|
"userId": "user-001",
|
||||||
|
"participatedAt": ISODate("2024-01-21T06:30:45.123Z"), // BSON Date (ms)
|
||||||
|
"nanoAdjustment": 456789, // Int (0-999999)
|
||||||
|
"metadata": { ... }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
| 필드 | 타입 | 설명 |
|
||||||
|
|------|------|------|
|
||||||
|
| `participatedAt` | BSON Date | 밀리초 정밀도, UTC 저장 |
|
||||||
|
| `nanoAdjustment` | Int | 0-999999 (서브밀리초 나노) |
|
||||||
|
|
||||||
|
## 설계 결정 사항
|
||||||
|
|
||||||
|
### 1. Offset 저장 안함
|
||||||
|
- Client가 i18n parameter (country code)를 요청 시 전달
|
||||||
|
- Server에서 응답 시 해당 timezone으로 변환하여 반환
|
||||||
|
- 별도 offset 저장 불필요
|
||||||
|
|
||||||
|
### 2. BSON Date 사용 이유
|
||||||
|
- Native MongoDB 타입 → Shell 쿼리 용이 (`ISODate()`)
|
||||||
|
- 효율적인 인덱싱 및 범위 쿼리
|
||||||
|
- Custom Converter 불필요 (Zero overhead)
|
||||||
|
|
||||||
|
### 3. 나노초 분리 저장
|
||||||
|
- BSON Date는 ms까지만 지원
|
||||||
|
- `nanoAdjustment` 필드로 sub-ms 나노초 보존
|
||||||
|
- 복원: `Instant.ofEpochMilli(ms).plusNanos(nanoAdjustment)`
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 요청 시간 캡처 아키텍처
|
||||||
|
|
||||||
|
### 문제
|
||||||
|
- Controller나 Service에서 `Instant.now()` 사용 시 실제 클라이언트 클릭 시간과 차이 발생
|
||||||
|
- 클레임 발생 가능성
|
||||||
|
|
||||||
|
### 해결: 계층별 타임스탬프 캡처
|
||||||
|
|
||||||
|
```
|
||||||
|
┌─────────────────────────────────────────────────────────────────┐
|
||||||
|
│ Client Click │
|
||||||
|
│ │ │
|
||||||
|
│ ~50-500ms 지연 │
|
||||||
|
│ ▼ │
|
||||||
|
│ ┌───────────────────────────────────────────────────────────┐ │
|
||||||
|
│ │ Ingress/LB (Nginx, ALB) │ │
|
||||||
|
│ │ → X-Request-Start-Time: $msec 헤더 추가 ⭐ 가장 정확 │ │
|
||||||
|
│ └───────────────────────────────────────────────────────────┘ │
|
||||||
|
│ │ │
|
||||||
|
│ ▼ │
|
||||||
|
│ ┌───────────────────────────────────────────────────────────┐ │
|
||||||
|
│ │ RequestTimestampFilter (Servlet Filter) │ │
|
||||||
|
│ │ 1. X-Request-Start-Time 헤더 파싱 │ │
|
||||||
|
│ │ 2. 없으면 Instant.now() (차선책) │ │
|
||||||
|
│ │ 3. ThreadLocal + MDC 저장 │ │
|
||||||
|
│ └───────────────────────────────────────────────────────────┘ │
|
||||||
|
│ │ │
|
||||||
|
│ ▼ │
|
||||||
|
│ ┌───────────────────────────────────────────────────────────┐ │
|
||||||
|
│ │ Service │ │
|
||||||
|
│ │ → RequestTimestampHolder.get() 으로 시간 조회 │ │
|
||||||
|
│ └───────────────────────────────────────────────────────────┘ │
|
||||||
|
└─────────────────────────────────────────────────────────────────┘

||||||

### Filter vs Interceptor
|
||||||
|
|
||||||
|
| 구분 | Filter | Interceptor |
|
||||||
|
|------|--------|-------------|
|
||||||
|
| **실행 시점** | DispatcherServlet **이전** | DispatcherServlet **이후** |
|
||||||
|
| **소속** | Servlet 스펙 | Spring MVC |
|
||||||
|
| **정확도** | ⭐⭐⭐ 더 정확 | ⭐⭐ 덜 정확 |
|
||||||
|
|
||||||
|
**결론: Filter가 더 빠르므로 Filter 사용 권장**
|
||||||
|
|
||||||
|
### Nginx 설정
|
||||||
|
|
||||||
|
```nginx
|
||||||
|
location / {
|
||||||
|
proxy_set_header X-Request-Start-Time $msec;
|
||||||
|
proxy_pass http://backend;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Kubernetes Ingress
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: networking.k8s.io/v1
|
||||||
|
kind: Ingress
|
||||||
|
metadata:
|
||||||
|
annotations:
|
||||||
|
nginx.ingress.kubernetes.io/configuration-snippet: |
|
||||||
|
proxy_set_header X-Request-Start-Time $msec;
|
||||||
|
```

# Gradle start up script for POSIX generated by Gradle.
|
||||||
|
#
|
||||||
|
# Important for running:
|
||||||
|
#
|
||||||
|
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||||
|
# noncompliant, but you have some other compliant shell such as ksh or
|
||||||
|
# bash, then to run this script, type that shell name before the whole
|
||||||
|
# command line, like:
|
||||||
|
#
|
||||||
|
# ksh Gradle
|
||||||
|
#
|
||||||
|
# Busybox and similar reduced shells will NOT work, because this script
|
||||||
|
# requires all of these POSIX shell features:
|
||||||
|
# * functions;
|
||||||
|
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||||
|
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||||
|
# * compound commands having a testable exit status, especially «case»;
|
||||||
|
# * various built-in commands including «command», «set», and «ulimit».
|
||||||
|
#
|
||||||
|
# Important for patching:
|
||||||
|
#
|
||||||
|
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||||
|
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||||
|
#
|
||||||
|
# The "traditional" practice of packing multiple parameters into a
|
||||||
|
# space-separated string is a well documented source of bugs and security
|
||||||
|
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||||
|
# options in "$@", and eventually passing that to Java.
|
||||||
|
#
|
||||||
|
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||||
|
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||||
|
# see the in-line comments for details.
|
||||||
|
#
|
||||||
|
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||||
|
# Darwin, MinGW, and NonStop.
|
||||||
|
#
|
||||||
|
# (3) This script is generated from the Groovy template
|
