Using a Go map with a sync.Mutex (or sync.RWMutex) is the most commonly advocated approach to caching. This does result in all the goroutines blocking upon one lock, which can lead to contention. This also fails to keep a tab on the amount of memory usage. Writing data at the speed of 160 MB/s and reading it at 80 MB/s, Badger is the fastest LSM Tree-based Key-Value Store written in Go. List: DoublyLinkedList for storing the cache values using container/list provided by go packages. I added one row into the database for testing purposes: Sending a request to our API for player with Id of 1, gives us: Sending another request for a player with Id of 2 (this one is from our database): Now, lets take a look at our Gin API.

GORM provides the method DB which returns a generic database interface *sql.DB from the current *gorm.DB // Get generic database object sql.DB to use its functionssqlDB, err := db.DB()// PingsqlDB.Pin Therefore, clients can now reuse responses without consulting Redis through the network until receiving the corresponding invalidation notifications. Go is one of the newest languages to get an official MongoDB driver, and the combination of Gos compiled performance and lightweight, data-friendly syntax makes Go with MongoDB a fantastic match for building data-driven applications. Cache data is stored in memory and not in a file within the Lambda execution environment.
