Compogo Cache

Плагинная система кэширования для фреймворка Compogo.

Построена на основе gocache и предоставляет:

• Единый интерфейс для работы с кэшем
• Поддержку различных драйверов (Redis, Memcached, in-memory)
• Автоматические метрики Prometheus
• Конфигурацию через флаги

Установка

go get github.com/Compogo/cache

Быстрый старт

package main

import (
    "context"
    "time"

    "github.com/Compogo/cache"
    "github.com/Compogo/compogo"
    "github.com/eko/gocache/lib/v4/store"
)

func main() {
    app := compogo.NewApp("myapp",
        compogo.WithComponents(&cache.Component),
    )

    app.AddComponents(&compogo.Component{
        Name: "my_service",
        Init: compogo.StepFunc(func(container compogo.Container) error {
            return container.Invoke(func(c cache.Cache) error {
                ctx := context.Background()
                
                // Сохранение
                err := c.Set(ctx, "key", []byte("value"), store.WithExpiration(time.Minute))
                if err != nil {
                    return err
                }
                
                // Чтение
                data, err := c.Get(ctx, "key")
                if err != nil {
                    return err
                }
                
                return nil
            })
        }),
    })

    if err := app.Serve(); err != nil {
        panic(err)
    }
}

Конфигурация

Флаги командной строки

# Драйвер кэша
--cache.driver=redis

# Время жизни по умолчанию
--cache.expiration=5m

Регистрация драйверов

import "github.com/Compogo/cache"

// Регистрация кастомного драйвера
func init() {
    cache.Registration(cache.Driver("custom"), func(container compogo.Container) (store.StoreInterface, error) {
        var client *CustomClient
        container.Invoke(func(c *CustomClient) { client = c })
        return custom.NewStore(client), nil
    })
}

Метрики Prometheus

Кэш автоматически собирает метрики:

# Метрики gocache
cache_hit_total{result="hit", cache_type="...", app="myapp"}
cache_miss_total{result="miss", cache_type="...", app="myapp"}
cache_set_success_total{result="success", cache_type="...", app="myapp"}
cache_set_error_total{result="error", cache_type="...", app="myapp"}
cache_delete_success_total{result="success", cache_type="...", app="myapp"}
cache_delete_error_total{result="error", cache_type="...", app="myapp"}

Зависимости

• Compogo — основной фреймворк
• gocache — библиотека кэширования
• Prometheus — метрики
