# Proposed changes
Issue Number: close #xxx
The former logic of client_cache would use two unordered_map, one for
<HostAddress, List<ClientPointer>> while the other for <ClientPointer,
ImplPointer>. Lock should be acquired no matter accessing whichever map.
Actually we can use one pair to maintain the <ClientPointer, ImplPointer>
relation to reduce the lock pressure.
## Problem summary
Describe your changes.
Remove client_cache map and use pair to maintain the <ClientPointer,
ImplPointer> relation.
