Nice to see consistent hashing go from obscure to blindingly obvious in a few short whitepapers.
Dynamo is certainly the sexiest discussion of distributed hash tables (DHTs), while Programmerâ€™s Toolbox Part 3: Consistent Hashing is the most straightforward. libketama is open and easy to use implementation of the 64-bit space mapped to a circle style consistent hash, discussed above and originally “popularized” by Chord. (and proposed over a decade ago)
And best quote:
“…and if anyone tells you that you shouldn’t use MD5 for this because it isn’t secure, just nod and back away slowly. You have identified someone not worth arguing with.”
