Thanks for the suggestion. raft is surely going to need some way to decrease the size of the InstallSnapshot
RPC in the future, another option would be to send the snapshots in chunks over the wire.
regarding bsdiff
, in the manpage:
BSDIFF(1) BSD General Commands Manual BSDIFF(1)
NAME
bsdiff — generate a patch between two binary files
SYNOPSIS
bsdiff ⟨oldfile⟩ ⟨newfile⟩ ⟨patchfile⟩
DESCRIPTION
bsdiff compares ⟨oldfile⟩ to ⟨newfile⟩ and writes to ⟨patchfile⟩ a binary patch suitable for use by bspatch(1). When ⟨oldfile⟩ and ⟨newfile⟩ are two versions of an executable pro‐
gram, the patches produced are on average a factor of five smaller than those produced by any other binary patch tool known to the author.
bsdiff uses memory equal to 17 times the size of ⟨oldfile⟩, and requires an absolute minimum working set size of 8 times the size of oldfile.

The fact that bsdiff would use memory 17! times the size of oldfile
will be problematic, but the idea to generate a diff could be interesting.
