What scalability strategies are possible with YSQL?
This question because the Postgre drivers allow you to connect to a single server. I am looking for information and examples.
I think it can behave correctly in Kubernetes (I have not tried).
May be a connections pool?
Another design feature is that each yugabyte node runs a proxy that can forward requests to the appropriate node responsible for the rows involved in that query.
@dorian_yugabyte has already listed different ways in which queries can be routed in a round-robin or other fashion to multiple nodes in the database (which will then forward requests to the right node for the query internally). For Kubernetes specifically, another option is to use the inbuilt service load balancer as described in the Helm chart documention for yugabyte. This eliminates the need to install separate loadbalancer software.
