Trino Generation of the Table Definition when connecting to Mongo DB

[NicolasSaikali]

I have thought about ways to refresh the table definition collection "_schema" and came up with the following idea:
When I need to introduce/edit/remove a field, I migrate my documents, then drop the "_schema" collection. So the next time I execute a query, trino will regenerate it, but I've notived that sometimes there is a delay of around 30 seconds for trino to regenerate it, in the mean time it will return the previous schema.

Why is this happening?
Is this caching? Can I do some configuration to change that?

So after going through trino code, I think this is the reason behind the delay
