+The next available change sequence number is stored as UTF-8 text in a
+blob pointed to by the `refs/sequences/changes` ref in the `All-Projects`
+repository. Multiple processes share the same sequence by incrementing
+the counter using normal git ref updates. To amortize the cost of these
+ref updates, processes increment the counter by a larger number and
+hand out numbers from that range in memory until they run out. This
+configuration parameter controls the size of the change ID batch that
+each process retrieves at once.
