How to Store Code Intelligence Graphs Efficiently

There are generally two practical approaches people consider: Store dependencies as adjacency lists (custom structure) Use a graph database This post breaks down how each approach behaves across: Creation Updates Deletion Maintenance Storage internals Time complexity The Problem: Code is a Graph Example: Function Structure in a Real Repo Consider a simple codebase: // auth.js export function validateUser () { checkAuth (); logAccess (); } function checkAuth () { dbQuery (); } // db.js export fun
