Category:	MySQL Server: Optimizer	Severity:	S3 (Non-critical)
Version:	5.7.29	OS:	Any
Assigned to:		CPU Architecture:	Any

File:	Maximum allowed size is 50MB.
Description:
Privacy:

If the data you need to attach is more than 50MB, you should create a compressed archive of the data, split it to 50MB chunks, and upload each of them as a separate attachment.

To split a large file:

On *nix platforms use the split command e.g. split -b 50MB <my_large_archive> <my_split_archive_prefix>
On windows use WinZip or a similar utility to split the large file

Test outputs on my instance

Attachment: test.output (application/octet-stream, text), 15.89 KiB.

Test script

Attachment: test.sql (application/sql, text), 5.88 KiB.

As a curiosity: it happens with any WHERE condition if you use MyISAM

Attachment: test.myisam.output (application/octet-stream, text), 16.35 KiB.
