Hi,
As the download-able products have their binaries stored in the database,
1. So is there any restriction of the length of the file?
2. Additionally the file is  loaded into the memory before its served to the user, does this translate to any constraint if I want to use the download-able products of size as much as 300mb.
3. Further, in-case I have a download-able file of size 75MB and multiple users are downloading that file concurrently does that mean the file would be loaded multiple times in the server memory, or is it loaded only once and that is used to serve to multiple users?

Please clarify, thanks in advance.
