TtlMap

Redis-like Map with expiry times and maximum capacity

import "github.com/mailgun/ttlmap"

mh, _ := ttlmap.NewMap(20)
mh.Set("key1", "value", 20)
valI, exists := mh.Get("key2")
if exists {
   val := valI.(string)
}

The ttlmap is not thread safe by default. You can either create a thread safe instance with ttlmap.NewConcurrent that is effectively using sync.RWLock, or implement locking in you application. Beware though that at the application level sync.RWLock cannot be used, because ttlmap.Get can occasionally modifies the internal data structure.
