I want to configure a Heavy Forwarder to forward to a set of Heavy Forwarders, which are then distributing to a Indexer Cluster.
My question in the Heavy Forwarder to Heavy Forwarders, would that be load balanced? So do I configure the 1st Heavy Forwarder with the details of the 2nd 'layer' of Heavy Forwarders and will it then load balance the traffic to them?
Or do I need to put something in between to do that load balancing?
yes you can configure with regular outputs.conf load balancing configurations to the "Intermediate Forwarders" Layer than another outputs.conf load balancing from each "Intermediate Forarder" to the Indexers layer.
why do you need an intermediate forwarders layer? do they have to be "Heavy Forwarders"?
as a general rule of thumb, it is best to avoid HF when possible
OK thats good, we need HF's at some point in the chain as we do a number of transforms, and some of the add-ons we use will only work on heavy forwarders as opposed to universal. So at the least we need them in the 'front' layer, I guess we could use Universals at the middle layer but we already have a bunch of HF's in place already so we may as well use them.
