Build Update for ovsrobot/ovn
Duration: 20 mins and 18 secs
Commit: 9be88ba (series_200461)
Author: Numan Siddique
Message: ovn-controller: Cache logical flow expr matches.
This patch is a second attempt in caching the expr tree of logical flows.
Earlier attemp  was reverted.
In this approach, we do the following
- If a logical flow match has any port group/address set references, we don't
cache expr match or expr tree.
- If a logical flow match doesn't have a port group/address set reference and
expr condition match - is_chassis_resident, we cache the expr matches
(which is hmap of struct expr_match *).
- If a logical flow match has expr condition match - is_chassis_resident we
cache the simplified 'expr' tree.
Caching is configurable and can be disabled if desired. The second patch of this series
added this support.
In my testing, a complete lflow_run() took around 5 seconds for around 90k logical flows,
where as it took around 2 seconds with caching.
