I am using AppEngine Studio to configure a CSV import. In the source configuration pane I uploaded a CSV file. In the Map to target pane I configured a mapping, and I selected four of the fields to require matching. Then use the schedule imports pane to execute the import.
After one such import, I have roughly 50k entries in the table.
After another such import, I have roughly 100k entries in the table.
The CSV has not changed, hence the matching fields in the records should have lead to an update rather than an insert. How can I in detail find out what happened, and how can I fix it?
