Apache AGE Stress-Tested: How PostgreSQL's Graph Extension Holds Up Under Load

Developers investigating Apache AGE, a graph extension for PostgreSQL, discovered segmentation faults that prompted a broader performance inquiry. Apache AGE allows users to query graph data directly within PostgreSQL using openCypher, eliminating the need for a separate graph database. The extension stores vertices and edges in standard PostgreSQL tables, automatically creating child tables when new node or relationship types are introduced. Researchers found no existing benchmarks or published performance results for Apache AGE, making a from-scratch investigation necessary. The study aimed to assess both the stability and performance characteristics of the extension under stress conditions.

Developer Reflects on Using Docker Repeatedly Without Truly Understanding It

A developer shares how they used Docker multiple times before grasping what it actually does, starting with running a local AI model via Ollama in March 2026. Subsequent uses included setting up an n8n automation workflow and deploying Hyperledger blockchain services, each time following instructions without deeper comprehension. The turning point came during an internship involving an observability stack with tools like Grafana, Prometheus, and the ELK stack, where Docker Compose made multi-service setup noticeably faster than manual installation. The developer now understands Docker as a way to package an application alongside its required environment for consistent execution across systems. They are currently building familiarity with core concepts such as images, containers, volumes, networks, and Dockerfiles, while acknowledging that Docker's internals remain unclear.
