> The Managed State used a lot of lock, which could impact a lot on
> performance.
> AbstractManagedStateImpl.getValueFromBucketSync(long, long, Slice) lock the
> buck to get value, But if the value still in memory, the lock is not
> necessary as flash is ConcurrentMap.
> probably AbstractManagedStateImpl should only lock when add/remove bucket.
> And bucket handle read/write lock inside bucket
