CSV sample with 10,000 rows

Why test with this file

Large enough to show how an import behaves under load: whether it streams the file or reads it whole, how long a database insert takes, and whether the browser stays responsive while a grid renders.

What to check

After your application has processed sample-csv-10000-rows.csv, confirm that:

• The record with the id 10000 arrives, so nothing was cut off by a row limit, a timeout or a request-size cap.
• Memory use stays flat while the file is read, and a progress indicator moves steadily instead of jumping from 0 to 100%.
• The import finishes inside your time budget, and running it twice does not create 20,000 records.
