Guys, just create 2 kind of blobs:

Compressed or uncompressed. Even better, we may have diferent
compression technics and determine what one (or no compression at all)
we want to use when declaring the blob. The compression level can be
configurable too, so we can balance compression speed with compressed
data size.

This is a simple idea that would some everyone problems.

PS: Since I'm not a FB core developer, I do not know what would be
the cost of "coding" this, but I'm sure this can be done.
