127: Ecto gets Lively in Livebook
Thinking Elixir Podcast
Visualize a Change Set
I really appreciate the visual way of presenting how the plan looks and what's slow or not. So you went over the entity relationship diagram, the ERD. That's good for trying to figure out why a query might be slow. But then there's another thing where you visualize a change set. I hadn't thought about visualizing a change set, but that seems compelling.
We talked with Spawnfest competitors Filipe Cabaço & Joel Carlbark about their entry “Lively”. Lively was all about doing cool things with Ecto in Livebook. The project, later renamed to KinoEcto does 4 cool things around Ecto in Livebook. It builds Entity Relationship diagrams from the Ecto Schemas in your Elixir project. It can visualize the dense Postgres explain output and highlight a problem like when a full table scan is performed. It includes a ChangesetValidator SmartCell, and a QueryBuilder that uses NimbleParsec to parse a raw SQL query and do the initial work of turning that into an Ecto query. We talk about what the 48-hour competition was like, what they accomplished and what they plan to do next!
