Constants ¶
const ( PrefixSecret = "secret:v1:" PrefixCustomer = "customer:v1:" PrefixUser = "user:v1:" PrefixTenant = "tenant:v1:" PrefixPlan = "plan:v1:" PrefixPrice = "price:v1:" PrefixMeter = "meter:v1:" PrefixEvent = "event:v1:" PrefixWallet = "wallet:v1:" PrefixInvoice = "invoice:v1:" PrefixFeature = "feature:v1:" PrefixEntitlement = "entitlement:v1:" )
Predefined cache key prefixes for different entity types
const DefaultCleanupInterval = 1 * time.Hour
DefaultCleanupInterval is how often expired items are removed from the cache
const DefaultExpiration = 30 * time.Minute
DefaultExpiration is the default expiration time for cache entries
const (
ExpiryDefaultInMemory = 30 * time.Minute
)

Functions ¶
func GenerateKey ¶
GenerateKey creates a cache key from a prefix and a set of parameters It joins all parameters with a colon and appends them to the prefix
func InitializeInMemoryCache ¶
func InitializeInMemoryCache()
InitializeInMemoryCache initializes the global cache instance
Types ¶
type Cache ¶
type Cache interface {
// Get retrieves a value from the cache
// Returns the value and a boolean indicating whether the key was found
Get(ctx context.Context, key string) (interface{}, bool)
// Set adds a value to the cache with the specified expiration
// If expiration is 0, the item never expires (but may be evicted)
Set(ctx context.Context, key string, value interface{}, expiration time.Duration)
// Delete removes a key from the cache
Delete(ctx context.Context, key string)
// DeleteByPrefix removes all keys with the given prefix
DeleteByPrefix(ctx context.Context, prefix string)
// Flush removes all items from the cache
Flush(ctx context.Context)
}
Cache defines the interface for caching operations
type InMemoryCache ¶
type InMemoryCache struct {
// contains filtered or unexported fields
}
InMemoryCache implements the Cache interface using github.com/patrickmn/go-cache
func GetInMemoryCache ¶
func GetInMemoryCache() *InMemoryCache
GetCache returns the global cache instance
func Initialize ¶
func Initialize(log *logger.Logger) *InMemoryCache
Initialize initializes the cache system
func (*InMemoryCache) Delete ¶
func (c *InMemoryCache) Delete(_ context.Context, key string)
Delete removes a key from the cache
func (*InMemoryCache) DeleteByPrefix ¶
func (c *InMemoryCache) DeleteByPrefix(_ context.Context, prefix string)
DeleteByPrefix removes all keys with the given prefix
func (*InMemoryCache) Flush ¶
func (c *InMemoryCache) Flush(_ context.Context)
Flush removes all items from the cache
