Steven Hawkins commented on TEIIDSB-64:
---------------------------------------
Also it looks like we'll want to set service.spec.sessionAffinityConfig.clientIP.timeoutSecond for pg/jdbc - the default is 10800 seconds or 3 hours.

> Teiid's pg, and jdbc assume session affinity. Also OData pagination works best with session affinity.
> For HA, and horizontal scaling, it would be good to have more than 1 pod alive and receiving traffic. It appears that there is a sessionAffinity setting at a service level https://kubernetes.io/docs/concepts/services-networking/service/ and some work that can be done to customize routes https://docs.openshift.com/container-platform/3.9/architecture/networking/routes.html#routes-sticky-sessions - but that doesn't appear to work for just tcp traffic.
