Hi Ben,
I gave these patches another look, and I can say that for patches 1-10,
and patch 27:
Acked-by: Mark Michelson <[email protected]>
For patch 11, I had suggested previously a configure-time check to
detect if the correct DDLog version was installed, and you replied with
an example that you would roll into the next version of the series. But
I don't see it here. Is it in a different patch series?
For patches 12-26, I don't feel qualified to definitively state that
it's the "best" way to optimize things, but the changes all make sense
to me and don't seem to be incorrect, so for patches 12-26:
Acked-by: Mark Michelson <[email protected]>
but I wouldn't be averse to others having a look to be certain.
Thanks!

This series of patches greatly improves the performance of
ovn-northd-ddlog with the benchmark added in the final patch. The
first three patches improve both the benchmark for both versions of
ovn-northd.
Here are the timings that I measure in each case. All of them
include the benefit of the first three patches. Without those
patches, the C version takes over 500 seconds and the other take much
longer too; the relative timings aren't affected much, it's just all
slower:
C: 106.8s (0.135s ... 1.043s)
ddlog before optimization patches: 176.0s (0.128s ... 1.804s)
ddlog after optimization patches: 35.2s (0.129s ... 0.147s)
(I haven't re-measured for v3.)
v1->v2:
- Don't remove --output-only-table option from ovsdb2ddlog2c
in "ovn-northd-ddlog: Intern selected input relations.".
- New patches "ovn-nbctl: Daemon mode is no longer experimental."
and "ovn-nbctl: Recommend ovn-appctl instead of ovs-appctl."
and make similar changes to new ovn-sbctl manpage.
- Update ovn-sbctl and ovn-nbctl manpages to reference ovn-appctl
manpage.
- Various trivial changes suggested by checkpatch.
- New patches "ovn-nbctl: Fix memory leak in client mode."
and "ovn-northd-ddlog: Fix two memory leaks." fix memory leaks
reported by Numan and found by Address Sanitizer.
- Fix bug introduced into ovsdb2ddlog2c in "ovn-northd-ddlog: Intern
selected input relations."
v2->v3:
- Rebase.
- Apply Mark Michelson's comments for "ovn-sbctl: Add daemon support."
and to "tests: Miscellaneous debuggability improvements.".
- New patch "ovn-nbctl: Don't replicate entire database unnecessarily."
