What is Axiom-JSON and how does it work?

Axiom-JSON is an open-source C extension that memory-maps JSON files and uses pointer scans to query without full Python object creation — slashing RAM to near-zero.

How much faster is Axiom-JSON vs standard json.loads()?

11.4x on 500MB files, from 3.2s to 0.28s, with infinite RAM scalability.

Is Axiom-JSON safe for production data pipelines?

Yes, once compiled — handles GB-scale files via OS paging, perfect for AWS/GCP log processing without OOM crashes.
