Category:	MySQL Server: InnoDB storage engine	Severity:	S5 (Performance)
Version:	8.0.29	OS:	Oracle Linux (Oracle Linux Server release 7.9 3.10.0-1160.76.1.0.1.el7.x86_64)
Assigned to:		CPU Architecture:	x86 ( Intel(R) Xeon(R) CPU E5-2630 v3 )

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
