We definitely don't want to be pulling frags over the cluster network. 21:20:38 reid_g recently noticed that reconstructor GETs don't use the replication network. i've got a patch to change that (in the spirit of https://review.opendev.org/c/openstack/swift/+/735751) 21:20:47 #link https://review.opendev.org/c/openstack/swift/+/812614 21:21:09 thanks for the reviews; i'll write up a bug and some tests shortly 21:21:30 that's all i've got 21:21:36 #topic open discussion 21:21:46 what else should we bring up this week? 21:23:03 We ran into a fun bug where account stats would get stuck. I wrote a probe test to prove it. And here is also the first attempt at fixing it: https://review.opendev.org/c/openstack/swift/+/811833 21:23:18 So any thoughts on that approach would be good. 21:24:46 The code was simple until acoles pointed out we'd need to support single replica container rings.. and the patch in essence only allows updates from non handoffs that have had an incoming sync. So opts for an escape hatch (config option) to override if your running with 1. (don't know why you would ever though) 21:25:38 it's a good corner case, and i like the config-option escape hatch. maybe better named something like "update_when_never_replicated" though? 21:26:20 ahh yeah nice, I suck at coming up with config option names :P 21:27:27 having spent time in the incoming_syncs code it does make me worry about some potentual extra work on some edgecases. But I might cofirm my understanding before I write up anything like a bug because I could be wrong :) 21:27:50 fwiw, i know i've played around with single-disk (so, single-replica) stuff before: https://github.com/tipabu/sds 21:28:09 it's worth making sure single-replica works for dev/test environments 21:28:45 cool, a usecase means it's worth the effort, thanks! 21:30:36 all right, let's make it a short meeting so you guys can get on with your mornings :-) 21:30:47 thank you all for coming, and thank you for working on swift! 21:30:54 #endmeeting
