Optimize affinity routing while making use of DISTRIBUTION_BASED consistent hash algorithm #763

Closed maulinpatel007 closed 2 years ago

maulinpatel007 commented 2 years ago

Added solution for optimizing affinity routing. Today existing affinity routing solution seems to be CPU or memory heavy and can only be enabled by POINT_BASED or MULTI_PROBE consistent hash algorithm.

This PR provides lightweight solution to achieve affinity routing while making use of DISTRIBUTION_BASED consistent hash algorithm.

Using this solution, applications can choose to optimize Affinity routing by providing implementation to AffinityRoutingUriProvider interface implementation and supply the instance in RequestContext's local attribute.
