Asami: Turn your JSON into a Graph in 2 Lines
summary
Asami claims it can load JSON in 2 Clojure lines and produce a queryable graph with schema-less RDF-like flexibility. Implementation details include a JVM and ClojureScript port, memory-mapped blocks, tuple storage with tree indexes (currently AVL), and number encoding for values so storage is four-column numeric arrays with copy-on-write trees. It offers time-travel queries, a CLI via GraalVM, real use inside Cisco SecureX, and a compact codebase of ~7k LOC vs 100k.
