> Issue Type: Improvement
> Components: server
> Affects Versions: 3.6.0

> We would like to have a better understanding of the type of workloads hit ZK,
> and one aspect of such understanding is to be able to answer queries of top N
> read and top N write request path. Knowing the hot request paths will allow
> us better optimize for such workloads, for example, enabling path specific
> caching, or change the path structure (e.g. break a long path to hierarchical
> paths).
