Which application or service?:  Hybrid

What type of connector? (SaaS, Database, File or Event Source):  Database (but really any that perform renaming)

Additional details:  When using Fivetran Naming and a duplicate column name is encountered due to renaming, do not drop one if the columns and lose the data.  Instead, rename one of the columns by adding a character like a '1' or prompt the user to resolve the duplicate name issue.

Example where the special character is replaced with an underscore causing a duplicate column name:

a$b -> a_b

a#b -> a_b
