> Priority: Major
> Labels: pull-request-available
>
> In the current ResourceLimitCache, write request data is removed from the
> stateMachineDataCache when the majority of the ratis peers have committed the
> request, which leaves the leader to fetch the write data from
> ContainerStateMachine if it hasn't assemble and send the corresponding
> appendEntities to the left follower.
> This task amis to improve the stateMachineDataCache hit rate by lazily remove
> element, that is, keep the element in the cache as long as possilbe.
> One drawback of using Gauva Cache is it cannot control the total cased data
> size, only data count is controlable.
