c-taylor opened a new issue #7517:
URL: https://github.com/apache/trafficserver/issues/7517
A primary use of per_server.connection.max is to limit the number of
upstream connections to an origin.
per_server.connection.match allows you to hash against {fqdn,ip} to apply
those limits. Such that many hostnames going to a single address can have a
separate limit defined.
However: In a multi-tiered deployment where "parents" are defined, this is
seemingly not possible. The fqdn seems to come from current.server->name which
in turn comes from the parent_info struct, and as such fqdn:ip is 1:1 and
'both' no longer has any value
child ->
child -> parent -> originA
child -> parent -> originB
child ->
Only being able to apply a meaningful fqn:ip limit outbound from the parent
doesn't allow inbound to be collapsed. So a slow originA will cause increased
impact on originB.
