How can we create streaming tables as external delta tables ?

We would like to introduce DLT, Streaming tables to our medallion architecture but we are unable to create the streaming tables with concerned schemas. STREAMING Tables doesn't have an option to be stored with custom schemas.

The requirement we have is to save these tables as external delta tables in S3 and able to query from Unity Catalog that we created. Here is example

poc_deltalake —> catalog name

bronze —> schema name

customers —> table name

select * from poc_deltalake.bronze.customers

Let me know if anyone is successful in creating that.

The DLT is storing everything in the schema that we gave but it is not giving an option to save the tables under a particular schema.

If unity catalog is used, by default tables under that would be managed

@Faisal How would this statement is a solution to my question ? Could you please elaborate ?

By default the tables in unity catalog are managed, but we are giving external location to make them external tables.
but I'm taking about having schema to stream tables to store them in a organized way as an external table.
