Hey @Product,
I just have a WA enhancement request. It appears that the 'Query table in Datastore' WA does not support querying rows based on their created or updated date.
I have a WF where I want to query a datastore table for rows created more than 15 minutes ago. After doing some tests, it appears the datastore_created_at field is not queryable, or at least it's not treated by a date.
This is a low-priority request since there is an easy workaround for this: add a subsequent Query JSON using SQL WA afterwards to query the rows further by their datastore_created_at. It works perfectly, it's just that it creates extra work.
