Concurrency-safe golang caching library with expiration capabilities.
Make sure you have a working Go environment (Go 1.2 or higher is required). See the install instructions.
To install cache2go, simply run:
go get github.com/muesli/cache2go
To compile it from source:
cd $GOPATH/src/github.com/muesli/cache2go
go get -u -v
go build && go test -v
package main
import (
"github.com/muesli/cache2go"
"fmt"
"time"
)
// Keys & values in cache2go can be of arbitrary types, e.g. a struct.
type myStruct struct {
text string
moreData []byte
}
func main() {
// Accessing a new cache table for the first time will create it.
cache := cache2go.Cache("myCache")
// We will put a new item in the cache. It will expire after
// not being accessed via Value(key) for more than 5 seconds.
val := myStruct{"This is a test!", []byte{}}
cache.Add("someKey", 5*time.Second, &val)
// Let's retrieve the item from the cache.
res, err := cache.Value("someKey")
if err == nil {
fmt.Println("Found value in cache:", res.Data().(*myStruct).text)
} else {
fmt.Println("Error retrieving value from cache:", err)
}
// Wait for the item to expire in cache.
time.Sleep(6 * time.Second)
res, err = cache.Value("someKey")
if err != nil {
fmt.Println("Item is not cached (anymore).")
}
// Add another item that never expires.
cache.Add("someKey", 0, &val)
// cache2go supports a few handy callbacks and loading mechanisms.
cache.SetAboutToDeleteItemCallback(func(e *cache2go.CacheItem) {
fmt.Println("Deleting:", e.Key(), e.Data().(*myStruct).text, e.CreatedOn())
})
// Remove the item from the cache.
cache.Delete("someKey")
// And wipe the entire cache table.
cache.Flush()
}
To run this example, go to examples/mycachedapp/ and run:
go run mycachedapp.go
You can find a few more examples here. Also see our test-cases in cache_test.go for further working examples.
