Which local DB/NoSQL support TTL and key-value store?

Question

I need a local key-value cache that support TTL. It need to have very powerful performance like hashmap and also support TTL for an entry. That would be cool if it can use local storage if memory is not enough.

Found LevelDB doesn't support TTL or batch delete. Sorry to pass this option because the performance is very good.

Any idea that can fulfill the requirement?

• Local key-value system
• Fast
• Support TTL
• Make full use of memory and better can use local disk when memory is not enough
