If it would be possible to tape/upload/livecast this, that would be neat too.

balancer_by_lua : Setting multiple peer addresses

rohit.c.joshi

If I have multiple hosts as a upstream request, can I set multiple hosts in balancer_by_lua block by calling

set_current_peer()

Sounds like you might be looking for location.capture_multi: https://github.com/openresty/lua-nginx-module#ngxlocationcapture_multi

Default upstream handlers won't be able to handle multiple peers.

When DNS resolves host name to multiple IP addresses, can I set all the IP addresses/peers?

You have to pick one. You can only connect to one endpoint for every
single TCP connection, for obvious reasons. And each time
balancer_by_lua* is invoked, it is for establishing a new backend TCP
connection. You decide the target of *that* new connection there.
