Problem you have encountered: Customer would like to have a single trigger listen to all documents in a collection and trigger
on any field update/delete in any document

For example :


6 documents A.B,C,D,E,F in a collection called LETTERS


Document A gets a new field added (string) .... trigger fires


Document E gets a field deleted (string) .... trigger fires


Please note that [1] outlined that Triggers happen at the document-level. It is not possible to create a trigger for a specific field only.

What you expected to happen:Customer would like to have a trigger that only pays attention to a particular field
