Yeah, it's purely a convenience view over |
This commit adds a new view, `mz_internal.mz_wallclock_global_lag` that shows the most recent wallclock lag values from all collections. The intention is to have something that's easier to use for people that want to inspect the current freshness of their objects and are not interested in historical values.
