Where 500 KB matters
A 512,000-byte file: larger than most API body limits, smaller than most upload limits. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Amazon DynamoDB items | 400 KB per item | 500 KB cannot be stored as a single item. |
| Express body parsers | 100 KB by default | Rejected unless the limit is raised. |
| nginx request body | 1 MB by default (client_max_body_size) | Accepted with room to spare. |
Use this file for
- Testing that APIs return 413 for oversized bodies
- Load-testing with many rows
- Seeding databases and demos
Testing notes for CSV
- Splitting each line on commas breaks on quoted fields. Test with the quoted-fields sample before trusting an importer.
- Excel opens CSV files using the system locale, so a file that works in one country shows everything in one column in another.
