Sounds logical, what's also nice to see, is that even though people here
tend to say "don't put binaries in the database", apparently Facebook
thought it would be nice to do so (for all sorts of reasons) and even
took
the time to write their own blob storage mechanism ;-)
The whole point is that they *aren't*' putting blobs in their database -
that has way too much overhead. They're using a custom service that does
nothing but "read from byte X to byte Y". No concepts of tablespaces,
integrity, indices, whatever.
The only thing they store in their database, is the start- and end-byte of
each image.
I doubt they even took it as far as to write a plugin engine - that would
again bring too much overhead.
Right, not the actual files, indeed. But not "just" on the file system
either,
interesting approach.
