cache

type Cache ¶

type Cache interface {
	Get(ctx context.Context, key string) (interface{}, error)
	Set(ctx context.Context, key string, value interface{}, ttl time.Duration) error
	Delete(ctx context.Context, key string) error
	DeletePattern(ctx context.Context, pattern string) error
	Exists(ctx context.Context, key string) (bool, error)
	Close() error
}

Cache interface defines caching operations.

Two implementations are provided:

• MemoryCache: Simple in-process LRU cache with global TTL
• RedisCache: Distributed cache with per-item TTL support

Use MemoryCache for development and single-instance deployments. Use RedisCache for horizontal scaling or when per-item TTL is needed.

type MemoryCache ¶

type MemoryCache struct {
	// contains filtered or unexported fields
}

MemoryCache implements an in-memory LRU cache. TTL is global, set at construction time via NewMemoryCache. For per-item TTL, use RedisCache instead.

func NewMemoryCache(size int, ttl time.Duration) *MemoryCache

func (m *MemoryCache) Close() error

func (m *MemoryCache) Delete(ctx context.Context, key string) error

func (m *MemoryCache) DeletePattern(ctx context.Context, pattern string) error

func (m *MemoryCache) Exists(ctx context.Context, key string) (bool, error)

func (m *MemoryCache) Get(ctx context.Context, key string) (interface{}, error)

func (m *MemoryCache) Set(ctx context.Context, key string, value interface{}, ttl time.Duration) error

type RedisCache ¶

type RedisCache struct {
	// contains filtered or unexported fields
}

RedisCache implements a Redis-backed cache

func NewRedisCache(host string, port int, ttl time.Duration) (*RedisCache, error)

func (r *RedisCache) Close() error

func (r *RedisCache) Delete(ctx context.Context, key string) error

func (r *RedisCache) DeletePattern(ctx context.Context, pattern string) error

func (r *RedisCache) Exists(ctx context.Context, key string) (bool, error)

func (r *RedisCache) Get(ctx context.Context, key string) (interface{}, error)

func (r *RedisCache) Set(ctx context.Context, key string, value interface{}, ttl time.Duration) error
