NodusDB

About

NodusDB is a Python library that evaluates Zanzibar-style authorization checks inside the application process instead of calling a separate service. It keeps the relationship graph in memory and writes every change to a signed, hash-linked log that can be queried as an Iceberg table for audit, time travel and erasure. The README reports a median check of 14 microseconds over 560,497 relationships, against several milliseconds for SpiceDB and OpenFGA measured over the network.
