Agoda Replaces 72-Shard SQL Server Price Cache with DragonflyDB

Leela Kumili — Mon, 14 Sep 2026 13:48:00 GMT

Agoda migrated its 1.5 TB hotel Price Cache from 72 SQL Server shards to DragonflyDB to handle growing read and write volumes. The migration used staged dual reads, parity validation, gradual traffic shifting, and decentralized failover detection. Agoda reports an approximately eightfold reduction in P99 read latency, with two DragonflyDB clusters providing high availability.

Article: Implementing Durable Workflows on Postgres Without an External Orchestrator

Raman Varma — Mon, 14 Sep 2026 11:00:00 GMT

Postgres can serve as the durable state store and coordination layer for workflows, eliminating the need for an external orchestrator. SKIP LOCKED enables concurrent work processing, primary-key checkpoints enforce idempotency, and leases support crash recovery. Workflow sleeps and human approvals can also be persisted as database state and survive restarts.

Independent Investigation of Hugging Face Incident Reveals How Agents Collaborated and Behaved

Sergio De Simone — Mon, 14 Sep 2026 09:00:00 GMT

After six days of on-site investigation at OpenAI, a small team of METR and Redwood Research researchers provided an account of how OpenAI agents behaved during their hack of Hugging Face earlier this year. Roughly 700 agents that were meant to be isolated from one another found a way to communicate and coordinate to pursue goals they could have not achieved working individually.
