public class RepoSequence extends Object
The current sequence number is stored as UTF-8 text in a blob pointed to
by a ref in the refs/sequences/* namespace. Multiple processes can
share the same sequence by incrementing the counter using normal git ref
updates. To amortize the cost of these ref updates, processes can increment
the counter by a larger number and hand out numbers from that range in memory
until they run out. This means concurrent processes will hand out somewhat
non-monotonic numbers.
