> The index fingerprint is currently being calculated on each segment sequentially. While this works fine, the index fingerprint calculation was noticed to be a very slow process and on leader election is blocking.
> This proposes to have this calculation parallelized across segments instead. Since the fingerprint is just a cumulative sum of a hash on versions, the order in which it is added to the running sum should not matter.
