Hi Ales,
Sorry for reviewing this so late in the cycle. I think the patch looks
OK. I mostly have some performance related concerns, it would be great
to get some scale testing numbers. The other comment I had is minor.

Does this create a measurable performance impact? We're going to
potentially walk all already assigned CT zones every time a new port is
bound locally. Should we cache the ovs_zone records and index them by
zone_id? That probably also means that we might need to add incremental
processing support for ovsrec_ct_zone.
On the other hand, I tried a quick test of binding 500 ovs interfaces to
LSPs in a sandbox (ovs and ovn compiled with gcc and -O2 and debug
logging disabled) and I didn't see any noticeable performance degradation.
Just to be sure, would it be possible to do some e2e performance
measurements with ovn-heater with this patch?

Same question about potential performance impact here too. Instead of
doing this in two steps wouldn't it make sense to actually store in the
ct_zone structure the requested limit already when we create the
structure (or the pending one)? We'd avoid this O(n log n) - I think -
complexity.
But, as mentioned above, if there's no visible e2e performance impact we
can probably avoid the complication and keep it as is.
