> Abstract a LockManager to manage locks.
> Some requirements for this LockManager:
> * Cached a fixed number lock instances, such as: 1000
> * Assign a Lock instance to a key and keep this mapping until the key
> released this instance
> * This LockManager needs a high performance, such as: QPS 1000w
>
> Some implementations that we can refer to:
> * alluxio.collections.LockPool in Alluxio
> * Implementation in MEITUAN
