CDM this Wednesday

Hey folks, December CDM is this Wednesday, Dec 2, at 1600 UTC (11am ET): https://bluejeans.com/908675367/ Please add topics here: https://tracker.ceph.com/projects/ceph/wiki/CDM_02-DEC-2020 So far we've got one topic - mgr scalability, particularly the progress module. Currently this module processes every pg map and osdmap update, which is quite costly. We may need to revisit which events we track and/or how we track them to limit cpu usage in larger clusters. See you there! Josh
