About Email wp-svbtle May 11, 2023 Traversing a tree stored as an adjacency list using a Recursive CTE built in SQLAlchemy This is part of a series on combining PostgreSQL Materialized Views, Recursive CTEs, and SQLAlchemy: Using SQLAlchemy to create and manage PostgreSQL Materialized Views Traversing a tree stored as an adjacency list using a Recursive CTE built in SQLAlchem y (this post) The problem: Recently, while working on the RockClimbing.com codebase, I encountered several situations where data needed to be pre-calculated/cached because on-the-fly calculations were too slow.
