Where 10 MB matters
A 10,485,760-byte file: over the default limits of PHP, API Gateway and Spring Boot requests. These are the default limits a file of this size is useful for testing:
| System | Limit | Note |
|---|---|---|
| Amazon API Gateway | 10 MB payload | A 10 MB file in a multipart or base64 body is over the limit. |
| Spring Boot multipart | 10 MB per request by default (max-request-size) | Exceeded once form overhead is added. |
| PHP | 8 MB POST body by default (post_max_size) | Rejected before the script runs. |
| Amazon S3 multipart upload | 5 MiB minimum part size | This file splits into exactly two minimum-sized parts. |
| Email attachments | Commonly 20 to 25 MB per message | 10 MB fits, at about 13.3 MB once encoded. |

- Measuring download speed from your own server or CDN
- Testing data pipelines that split fields on tabs
- Testing import features that accept more than one delimiter
Testing notes for TSV
- Windows does not open .tsv in Excel by default, so users rename files to .txt or .csv, and the extension stops describing the content.
- A field cannot contain a tab or a line break. Exporters deal with that in incompatible ways: some write backslash escapes such as \t, some apply CSV-style quotation marks, and some corrupt the row.
