We explored standard advanced algorithms like Contraction Hierarchies (CH), known for their speed. But they presented their own set of deal-breakers for OsmAnd:
An object’s OID is computed the same way git does it, SHA1(" \0"), using pgcrypto’s digest() function, and refs get compare-and-swap updates through SELECT FOR UPDATE. A libgit2 backend registers these tables as its storage layer, and if the protocol really is separable from the format, a normal git client should be able to push to and clone from a Postgres database without knowing the difference.
