go-cache is an in-memory key:value store/cache similar to memcached that is suitable for applications running on a single machine. Its major advantage is that, being essentially a thread-safe map[string]interface{} with expiration times, it doesn't need to serialize or transmit its contents over the network. Any object can be stored, for a given duration or forever, and the cache can be safely used by multiple goroutines. Although go-cache isn't meant to be used as a persistent datastore, the entire cache can be saved to and loaded from a file (using c.Items() to retrieve the items map to serialize, and NewFrom() to create a cache from a deserialized one) to recover from downtime quickly.
Features
- Return a new cache with a given default expiration duration and cleanup interval
- Add an item to the cache only if an item doesn't already exist for the given key
- GetWithExpiration returns an item and its expiration time from the cache
- Load and add cache items from the given filename
- Set a new value for the cache key only if it already exists
- Write the cache's items (using Gob) to an io.Writer
