1. Memgraph

   1 48 4,174 9.7 C++

   High-performance open-source in-memory graph database for GraphRAG, AI memory, agentic AI, and real-time graph analytics. Cypher-compatible, built in C++.

   

   Project mention: CI/CD Auto-Remediation: The Complete Guide for SRE and Platform Teams (2026) | dev.to | 2026-05-11

   Auto-remediating into a worse state. The classic failure is auto-scaling a service to handle elevated error rates that are themselves caused by a downstream dependency. The service scales, hammers the dependency harder, and the dependency collapses. Fix: never auto-remediate without dependency-graph awareness. Aurora uses Memgraph for this; HolmesGPT uses its toolset structure; pure-L1 stacks should require manual escalation when the failure crosses service boundaries.
