Hi Marcel,

yes, this is to be expected, because the schema is now logging more
kinds of events than before. However, we could reduce the sampling
rate considerably, as JonR and I had already envisaged
(https://phabricator.wikimedia.org/T120292#1854136 ; this got lost a
bit among the other schema changes, cf.
https://phabricator.wikimedia.org/T120292#1864549 ).
