openstackgerrit | Tim Burke proposed openstack/swift master: s3api: Better handle 503s in get_container_info, too https://review.opendev.org/759735 | 16:30 |
timburke | acoles, on p 759493 you said "I'm not sure how useful, or even desirable, it is to set minimum_servers > 1" -- should i maybe rework it all so that there's a simple yes/no config for whether error-limitng should be enabled? | 16:39 |
patchbot | https://review.opendev.org/#/c/759493/ - swift - memcache: make minimum number of servers configurable - 2 patch sets | 16:39 |
timburke | i feel like thre's still a case to be made that if i'm dramatically changing how i configure memcached such that each proxy is talking to a single (local) endpoint, it's preferable to have *some* attempt as using memcache rather than mobbing the db layers | 16:39 |
timburke | if the memcache errors are manifesting as timeouts, it applies some backpressure to clients which should be helpful. if (as it was in the case that prompted me to write the patch) it's a misconfiguration that causes some actions (say, incr/decr) to fail while others are fine, it's still better to use a degraded memcached than no cache at all | 16:42 |
timburke | 🤔 or maybe i should rework the patch to not even be configurable, and just make it so if you've got exactly one memcached server configured, we skip all error-limiting stuff... | 16:45 |

timburke | man, this seems to get stranger and stranger: http://lists.openstack.org/pipermail/openstack-discuss/2020-October/018304.html | 17:11 |
timburke | i just don't quite get how we end up at "tpool + Python 3.6.x + type hinting is fubar" | 17:12 |
acoles | timburke: I'm in favour of some kind of configurability if only to avoid even considering the change of default behaviour. I think I also mention of making the error limit parameters configurable (or did I imagine that?) in which case that may be sufficient i.e. for your case the error limit duration could be set to zero | 17:13 |
acoles | s/also mention/also saw mention/ | 17:14 |
timburke | yeah, pretty sure mattoliverau saw that as an immediate red flag that they were all hardcoded | 17:14 |
acoles | timburke: do you have a schedule of topics for each swift PTG session? or are we going to agree that in the first session? | 18:25 |
timburke | no formal schedule yet -- i think it'd be a good thing to kinda work out in the first session | 18:25 |
timburke | at the very least, pick a slot for some ops-feedback so i can get an announcement out to the ML | 18:26 |

mattoliverau | Morning, so just to confirm start time, off schedule says 22 utc, but live schedule says 21 utc. So thought I'd confirm which is correct. | 20:00 |
mattoliverau | *PDF shedule | 20:00 |
timburke | should be 2100 UTC | 20:02 |
timburke | and good morning, mattoliverau! | 20:03 |
