So I'm reading up on delta encoding, and I was looking around for some good examples of it. I think Google Chrome uses something like that for patch updates, rsync might, and the Wikipedia article implies that alot of online backup tools use this.
I'm curious if there are any good Java libraries out there that do this kind of work? There seem to be an abundance of *nix and C-based tools, but little or no Java equivalents that do much more than compress data structures.
In any event, this is an entirely new concept for me, so I'm curious to read up on anything about it, with a particular interest in seeing anyone using Java to do it.
Wikipedia lists several Java implementations for the VCDIFF delta format.
There also exist Java implementations of the rsync algorithm, which can be used to create binary diffs. They don't seem production-ready, but if you just want to see the code they're fine. See Any good rsync library for Java?.
