Envoy sidecar proxy session persistence?

Question

I recently came across envoy and it fits very well for my new project. However, I cannot find out if envoy supports something like Sticky Session. Does envoy support session persistence?

Answer 1

Though I haven't used these particular settings yet, I believe what you're looking for is going to be found in the load balancer sections). Namely one of the load balancers that do consistent hashing of requests:

• ring hash
• maglev

You'll want to choose your load balancer in your cluster configuration (lb_policy field) as well as set the specific config for the algorithm (ring_hash_lb_config field, etc)

Hope this helps!
