Tell us about your request

With Upload and ​​MemoryBuffer the upload process fails if you have files larger than 1 MB, we should mention in the docs that uploads are limited by containers, e.g. for Spring-Boot this sets bigger limits:

spring.servlet.multipart.max-file-size=50MB
spring.servlet.multipart.max-request-size=100MB

If you think this issue is important, add a 👍 reaction to help the community and maintainers prioritize this issue.

Also worth it to describe spring.servlet.multipart.enabled=false that disables multipart resolver in Spring.
By default Spring caches the upload and prevents upload handler / stream receiver from getting it, making upload event useless.
