Questions about this workflow
Can this report database changes over time?
It can compare results only if prior inventories are available to the automation or supplied in a data source. Otherwise it reports the current list.
Does this need a Canvas event?
No. This workflow uses a Notis schedule to periodically inspect ClickHouse.
