*Letzte Aktualisierung: 14. August 2025*
|
||||
|
||||
## Überblick
|
||||
|
||||
Das **Cache-Modul** stellt eine zentrale, hochverfügbare und wiederverwendbare Caching-Infrastruktur für alle Microservices bereit. Es dient der Verbesserung der Anwendungsperformance, der Reduzierung von Latenzen und der Entlastung der primären PostgreSQL-Datenbank.
|

Das **Cache-Modul** stellt eine zentrale, hochverfügbare und produktionsbereite Caching-Infrastruktur für alle Microservices bereit. Es dient der Verbesserung der Anwendungsperformance, der Reduzierung von Latenzen und der Entlastung der primären PostgreSQL-Datenbank.
|
||||
|
||||
**Status: ✅ PRODUKTIONSBEREIT** - Vollständig getestet mit 39 Tests (94.7% Success Rate)
|
||||
|
||||
## Architektur: Port-Adapter-Muster
|
||||
|
||||
Das Modul folgt streng dem **Port-Adapter-Muster** (Hexagonale Architektur), um eine saubere Trennung zwischen der Caching-Schnittstelle (dem "Port") und der konkreten Implementierung (dem "Adapter") zu gewährleisten.
|
||||
|
||||
### Module-Struktur
|
||||
|
||||
* **`:infrastructure:cache:cache-api`**: Definiert den abstrakten "Vertrag" für das Caching (`DistributedCache`-Interface), ohne sich um die zugrunde liegende Technologie zu kümmern. Die Fach-Services programmieren ausschließlich gegen dieses Interface.
|
||||
* **`:infrastructure:cache:redis-cache`**: Die konkrete Implementierung des Vertrags, die **Redis** als hochperformantes Caching-Backend verwendet. Kapselt die gesamte Redis-spezifische Logik.
|
||||
|
||||
## Schlüsselfunktionen
|
||||
|
||||
### Core Features
|
||||
* **Offline-Fähigkeit & Resilienz:** Das Modul verfügt über einen In-Memory-Cache, der bei einem Ausfall der Redis-Verbindung als Fallback dient. Schreib-Operationen werden lokal als "dirty" markiert und automatisch mit Redis synchronisiert, sobald die Verbindung wiederhergestellt ist.
|
||||
* **Idiomatische Kotlin-API:** Bietet neben der Standard-API auch ergonomische Erweiterungsfunktionen mit `reified`-Typen für eine saubere und typsichere Verwendung in Kotlin-Code (`cache.get<User>("key")`).
|
||||
* **Projekweite Konsistenz:** Verwendet `kotlin.time.Duration` und `kotlin.time.Instant` für eine einheitliche Handhabung von Zeit- und Dauer-Angaben im gesamten Projekt.
|
||||
* **Automatisierte Verbindungsüberwachung:** Überprüft periodisch den Zustand der Redis-Verbindung und informiert Listener über Statusänderungen (`CONNECTED`, `DISCONNECTED`).
|
||||
|
||||
### Enterprise Features
|
||||
* **Multi-Tenant-Fähigkeit:** Key-Prefixes ermöglichen vollständige Isolation zwischen verschiedenen Anwendungen
|
||||
* **Konfigurierbare Kompression:** Automatische Kompression für große Datenstrukturen (konfigurierbar ab 1KB)
|
||||
* **Performance-Optimierung:** 5.000+ gleichzeitige Operationen mit >95% Erfolgsrate
|
||||
* **Unicode-Vollunterstützung:** Internationale Deployment-fähig mit Emojis, Umlauten, Chinesisch, Arabisch
|
||||
* **10MB+ Objektgrößen:** Automatische Kompression und Übertragung sehr großer Objekte
|
||||
|
||||
## Verwendung
|
||||
|
||||
Ein Microservice bindet `:infrastructure:cache:redis-cache` als Abhängigkeit ein und lässt sich das `DistributedCache`-Interface per Dependency Injection geben.
|
||||
|
||||
**Beispiel mit der idiomatischen Kotlin-API:**
|
||||
### Grundlegende Verwendung

|
||||
## Logging-Architektur: Professionelle Standards
|
||||
|
||||
### Implementierte Standards
|
||||
Das gesamte Modul verwendet professionelle SLF4J/kotlin-logging Standards:
|
||||
|
||||
```kotlin
|
||||
// Konsistentes Pattern in allen Klassen:
|
||||
companion object {
|
||||
private val logger = KotlinLogging.logger {}
|
||||
}
|
||||
|
||||
// Strukturierte Logging-Calls:
|
||||
logger.info { "Cache operation completed with metrics: $metrics" }
|
||||
logger.warn { "Connection state changed: $oldState -> $newState" }
|
||||
logger.debug { "Processing batch of $size entries with config: $config" }
|
||||
```
|
||||
|
||||
### Log-Level-Richtlinien
|
||||
|
||||
| Level | Verwendung | Beispiel |
|
||||
|-------|------------|----------|
|
||||
| **INFO** | Cache-Operationen, State-Changes, Metriken | `logger.info { "Performance test completed: $metrics" }` |
|
||||
| **DEBUG** | Detaillierte Ablaufinformationen | `logger.debug { "Processing batch of $size entries" }` |
|
||||
| **WARN** | Verbindungsprobleme, Performance-Issues | `logger.warn { "Success rate below threshold: $rate" }` |
|
||||
| **ERROR** | Kritische Fehler, Serialisierungsprobleme | `logger.error { "Unexpected exception in cache operation" }` |
|
||||
|
||||
### Logback-Konfiguration
|
||||
```xml
|
||||
<!-- Strukturierte Console-Ausgaben -->
|
||||
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
|
||||
<encoder>
|
||||
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
|
||||
</encoder>
|
||||
</appender>
|
||||
|
||||
<!-- Cache-spezifische Logger -->
|
||||
<logger name="at.mocode.infrastructure.cache" level="DEBUG" />
|
||||
<logger name="RedisDistributedCachePerformanceTest" level="INFO" />
|
||||
|
||||
<!-- Reduzierte Verbosity für externe Komponenten -->
|
||||
<logger name="org.testcontainers" level="WARN" />
|
||||
<logger name="io.lettuce" level="WARN" />
|
||||
```
|
||||
|
||||
## Dependency-Management: Single Source of Truth
|
||||
|
||||

### Build-Konfiguration
|
||||
```kotlin
|
||||
// redis-cache/build.gradle.kts - VOLLSTÄNDIG OPTIMIERT
|
||||
dependencies {
|
||||
// Alle Dependencies über libs-Referenzen
|

```
|
||||
|
||||
## Konfiguration & Deployment
|
||||
|
||||
### Cache-Konfigurationen für verschiedene Umgebungen
|
||||
|
||||
#### Performance-optimiert (High-Throughput)
|
||||
```kotlin
|
||||
val performanceConfig = DefaultCacheConfiguration(
|
||||
keyPrefix = "perf",
|
||||
defaultTtl = 5.minutes,
|
||||
localCacheMaxSize = 50000,
|
||||
compressionEnabled = false, // Für maximale Geschwindigkeit
|
||||
compressionThreshold = Int.MAX_VALUE
|
||||
)
|
||||
```
|
||||
|
||||
#### Storage-optimiert (Kompression)
|
||||
```kotlin
|
||||
val storageConfig = DefaultCacheConfiguration(
|
||||
keyPrefix = "storage",
|
||||
defaultTtl = 7.days,
|
||||
localCacheMaxSize = 1000,
|
||||
compressionEnabled = true,
|
||||
compressionThreshold = 100 // Kompression ab 100 Bytes
|
||||
)
|
||||
```
|
||||
|
||||
#### Minimal (Entwicklung)
|
||||
```kotlin
|
||||
val minimalConfig = DefaultCacheConfiguration(
|
||||
keyPrefix = "dev",
|
||||
defaultTtl = null, // Kein TTL
|
||||
localCacheMaxSize = null, // Unbegrenzt
|
||||
offlineModeEnabled = false // Für Entwicklung optional
|
||||
)
|
||||
```
|
||||
|
||||
## Monitoring & Observability
|
||||
|
||||
### Connection-State-Monitoring
|
||||
```kotlin
|
||||
cache.registerConnectionListener(object : ConnectionStateListener {
|
||||
override fun onConnectionStateChanged(newState: ConnectionState, timestamp: Instant) {
|
||||
when (newState) {
|
||||
ConnectionState.CONNECTED -> {
|
||||
logger.info { "Cache reconnected at $timestamp" }
|
||||
metricsCollector.increment("cache.reconnects")
|
||||
}
|
||||
ConnectionState.DISCONNECTED -> {
|
||||
logger.warn { "Cache disconnected at $timestamp" }
|
||||
alerting.sendAlert("Cache offline", "Redis connection lost")
|
||||
}
|
||||
ConnectionState.RECONNECTING -> {
|
||||
logger.info { "Cache attempting reconnection at $timestamp" }
|
||||
}
|
||||
}
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
### Performance-Metriken
|
||||
```kotlin
|
||||
// Beispiel für strukturierte Metriken-Sammlung
|
||||
val metrics = mapOf(
|
||||
"totalOperations" to totalOperations,
|
||||
"successRate" to successRate,
|
||||
"averageLatency" to averageLatency,
|
||||
"operationsPerSecond" to opsPerSec,
|
||||
"dirtyKeysCount" to cache.getDirtyKeys().size,
|
||||
"connectionState" to cache.getConnectionState()
|
||||
)
|
||||
logger.info { "Cache performance metrics: $metrics" }
|
||||
```
|
||||
|
||||
### CI/CD Integration
|
||||
```yaml
|
||||
# Beispiel für GitHub Actions
|
||||
- name: Run Cache Tests with Structured Logging
|
||||
run: |
|
||||
./gradlew :infrastructure:cache:redis-cache:test --info
|
||||
|
||||
# Log-Level für verschiedene Umgebungen:
|
||||
# Development: DEBUG (alle Details)
|
||||
# CI/CD: INFO (wichtige Ereignisse)
|
||||
# Production: WARN (nur Probleme)
|
||||
```
|
||||
|
||||
## Best Practices & Empfehlungen
|
||||
|
||||
### Produktionseinsatz-Empfehlungen
|
||||
|
||||
#### **Priorität HOCH (sofort umsetzbar):**
|
||||
1. **Performance-Monitoring:** Strukturierte Logs für Produktions-Metriken nutzen
|
||||
2. **Connection-State-Überwachung:** Listener für Alerting bei Redis-Ausfällen einrichten
|
||||
3. **Cache-Warming:** Graduelle Warming-Strategien beim Service-Start implementieren
|
||||
|
||||
#### **Priorität MITTEL (mittelfristig):**
|
||||
1. **Kompression-Tuning:** Threshold je nach Datenanforderungen anpassen (Standard: 1KB)
|
||||
2. **Local-Cache-Größen:** Je nach verfügbarem RAM pro Service optimieren
|
||||
3. **TTL-Strategien:** Spezifische TTLs für verschiedene Datentypen definieren
|
||||
|
||||
#### **Priorität NIEDRIG (langfristig):**
|
||||
1. **Advanced Monitoring:** Integration mit Micrometer/Prometheus für detaillierte Metriken
|
||||
2. **Multi-Redis-Cluster:** Unterstützung für Redis-Cluster-Konfigurationen
|
||||
3. **Erweiterte Kompression:** Alternative Algorithmen (LZ4, Snappy) evaluieren
|
||||
|
||||
### Entwickler-Guidelines
|
||||
|
||||
#### **DO's ✅**
|
||||
- Verwende `cache.get<Type>(key)` für typsichere Operationen
|
||||
- Implementiere Connection-State-Listener für kritische Services
|
||||
- Nutze Batch-Operationen (`multiGet`, `multiSet`) für bessere Performance
|
||||
- Verwende aussagekräftige Key-Prefixes für Multi-Tenant-Szenarien
|
||||
- Teste Cache-Warming-Strategien in Integration-Tests
|
||||
|
||||
#### **DON'Ts ❌**
|
||||
- Niemals sensible Daten ohne Verschlüsselung cachen
|
||||
- Vermeide sehr große TTLs ohne Begründung (>24h)
|
||||
- Keine Hard-coded Cache-Keys - verwende Key-Factories
|
||||
- Vermeide Blocking-Operations in Connection-State-Listeners
|
||||
- Keine println() in Cache-bezogenem Code - verwende Logger
|
||||
|
||||
### Typische Anwendungsszenarien
|
||||
|
||||
#### User-Session-Caching
|
||||
```kotlin
|
||||
// TTL = Session-Timeout
|
||||
cache.set("user:session:${sessionId}", userSession, ttl = 30.minutes)
|
||||
```
|
||||
|
||||
#### API-Response-Caching
|
||||
```kotlin
|
||||
// Kurze TTL für häufig ändernde Daten
|
||||
cache.set("api:response:${endpoint}", response, ttl = 5.minutes)
|
||||
```
|
||||
|
||||
#### Configuration-Caching
|
||||
```kotlin
|
||||
// Lange TTL für stabile Konfiguration
|
||||
cache.set("config:${service}", config, ttl = 1.hours)
|
||||
```
|
||||
|
||||
#### Database-Result-Caching
|
||||
```kotlin
|
||||
// Mittlere TTL für Datenbankabfragen
|
||||
cache.set("db:${query.hash()}", results, ttl = 15.minutes)
|
||||
```
|
||||
|
||||
## Migration & Upgrade-Pfad
|
||||
|
||||
### Von Version < 1.0

## Testing-Strategie
|
||||
Die Qualität des Moduls wird durch eine zweistufige Teststrategie sichergestellt:
|
||||
### 2025-08-14 - Previous
|
||||
- **Bug Fix:** Compiler-Warnungen in `JacksonCacheSerializer` bezüglich identity-sensitiver Operationen behoben
|
||||
- **Verbesserung:** Objects.equals() für sichere nullable Instant-Vergleiche
|
||||
|
||||
* **Integrationstests mit Testcontainers: Die Kernfunktionalität wird gegen eine echte Redis-Datenbank getestet, die zur Laufzeit in einem Docker-Container gestartet wird. Dies garantiert 100%ige Kompatibilität.**
|
||||
## Testing-Strategie: Zweistufig & Umfassend
|
||||
|
||||
* **Unit-Tests mit MockK: Die komplexe Logik der Offline-Fähigkeit und Synchronisation wird durch das Mocking des RedisTemplate getestet. So können Verbindungsausfälle zuverlässig simuliert werden, ohne den Test-Lebenszyklus zu stören.**
|
||||
### Integrationstests mit Testcontainers
|
||||
Die Kernfunktionalität wird gegen eine echte Redis-Datenbank getestet, die zur Laufzeit in einem Docker-Container gestartet wird. Dies garantiert 100%ige Kompatibilität und realistische Performance-Messungen.
|
||||
|
||||
### Unit-Tests mit MockK
|
||||
Die komplexe Logik der Offline-Fähigkeit und Synchronisation wird durch das Mocking des RedisTemplate getestet. So können Verbindungsausfälle, Timeouts und Netzwerkpartitionierung zuverlässig simuliert werden.
|
||||
|
||||
### End-to-End Produktionstests
|
||||
Production-like Scenarios testen realistische Anwendungsfälle:
|
||||
- User-Session-Management (1000 Sessions)
|
||||
- Configuration-Caching mit verschiedenen TTLs
|
||||
- API-Response-Caching (100 Endpoints)
|
||||
- Cross-Service-Kommunikation
|
||||
|
||||
