[ovs-dev] [PATCH 0/7] Reduce memory consumption and time for Load_Balancer benchmark

[Ben Pfaff]

For the benchmark at
https://mail.openvswitch.org/pipermail/ovs-dev/2021-July/385333.html,
this reduces memory consumption from 115 GB to 17 GB and elapsed time
from 19 minutes to 5 minutes.

I think there's headroom for more improvement, because Leonid has some
cleverness that I haven't been able to successfully work in yet.

Ben Pfaff (7):
  ovn-northd-ddlog: Merge TaggedFLow and MeteredFlow into Flow.
  ovn-northd-ddlog: Use cheaper representation for stage_hint.
  ovn-northd-ddlog: Intern Stage.
  Intern all the matches and actions.
  ovn-northd-ddlog: Get rid of duplicate flows caused by stage_hint.
  ovn-northd-ddlog: Intern nb::Logical_Switch.
  ovn-northd-ddlog: Postpone expanding external_ids, stage_hint, tags.
