type CacheMiddleware ¶
type CacheMiddleware struct {
// contains filtered or unexported fields
}
CacheMiddleware for monitoror * * We need two types of Cache. * - UpstreamCache : serves as a circuit breaker to answer before executing the request. (By default, short TTL) * - DownstreamCache : serves as backup to answer the old result in case of service timeout. (By default, long TTL) * * UpstreamCache must be implemented on some routes only (and with variable expiration). * He is implemented as a decorator on the handler of each route * * DownstreamCache should be used instead of a timeout response. * So we look at the cache in the global error handler (see handlers/errors.go) * * To fill both store at the same time, I implemented a store wrapper that performs every actions on both store
func NewCacheMiddleware ¶
func NewCacheMiddleware(store cache.Store, downstreamDefaultExpiration, upstreamDefaultExpiration time.Duration) *CacheMiddleware
NewCacheMiddleware used config to instantiate CacheMiddleware
func (*CacheMiddleware) DownstreamStoreMiddleware ¶
func (cm *CacheMiddleware) DownstreamStoreMiddleware() echo.MiddlewareFunc
DownstreamStoreMiddleware Provide Downstream Store to all route. Used when route return timeout error
func (*CacheMiddleware) UpstreamCacheHandler ¶
func (cm *CacheMiddleware) UpstreamCacheHandler(handle echo.HandlerFunc) echo.HandlerFunc
UpstreamCacheHandler return the cached response if he finds it in the store. (Decorator Handlers)
func (*CacheMiddleware) UpstreamCacheHandlerWithExpiration ¶
func (cm *CacheMiddleware) UpstreamCacheHandlerWithExpiration(expire time.Duration, handle echo.HandlerFunc) echo.HandlerFunc
UpstreamCacheHandlerWithExpiration return the cached response if he finds it in the store. (Decorator Handlers)
