Architecture Notes: Datasette (via) I was interviewed for the first edition of Architecture Notes—a new publication (website and newsletter) about software architecture created by Mahdi Yusuf. We covered a bunch of topics in detail: ASGI, SQLIte and asyncio, Baked Data, plugin hook design, Python in WebAssembly, Python in an Electron app and more. Mahdi also turned my scrappy diagrams into beautiful illustrations for the piece.

PostgreSQL 10 introduced extremely flexible logical replication—in this post Craig Kerstiens explains how Citus use this new ability to re-balance shards (e.g. when you move from two to four physical PostgreSQL nodes) without downtime.

The easiest way to have no-downtime upgrades is have an architecture that can tolerate some subset of their processes to be down at any time. De-SPOF and this gets easier (not that de-SPOFing is always trivial).
