To really get the Jest client usable for production, we need to expose the following configurations:

• the pool sizes

• the different timeouts on the HTTP requests - it might even be a good idea to set the read timeout a bit higher by default (AFAICS the default for Jest is 3 seconds)

• the autodiscovery feature - which allows failover and discovery of new nodes in the cluster: there is a boolean and a frequency: we should at least expose the boolean

To be clear, the autodiscovery only brings "overall" failover, not "per-request" failover. It only implies that failing nodes will eventually be removed from the server list, but a failing request caused by a failing node will not be tried again on another node. Thus will still be valid even if we add autodiscovery.
