If a database is guaranteed not to change it opens up all kinds of interesting opportunities - from taking advantage of SQLite immutable mode and HTTP caching to bundling static copies of the database directly in a Docker container. The interesting ideas in Datasette explores this idea in detail. As my goals for the project have developed, I realized that read-only databases are no longer the right default. SQLite actually supports concurrent access very well provided only one thread attempts to write to a database at a time, and I keep encountering sensible use-cases for running Datasette on top of a database that is processing inserts and updates. So, as-of version 0.28 Datasette no longer assumes that a database file will not change. It is now safe to point Datasette at a SQLite database which is being updated by another process. Making this change was a lot of work - see tracking tickets #418 , #419 and #420 . It required new thinking around how Datasette should calculate table counts (an expensive operation against a large, changing database) and also meant reconsidering the ""content hash"" URLs Datasette has used in the past to optimize the performance of HTTP caches. Datasette can still run against immutable files and gains numerous performance benefits from doing so, but this is no longer the default behaviour. Take a look at the new Performance and caching documentation section for details on how to make the most of Datasette against data that you know will be staying read-only and immutable.","[""Changelog"", ""0.28 (2019-05-19)""]","[{""href"": ""https://simonwillison.net/2018/Oct/4/datasette-ideas/"", ""label"": ""The interesting ideas in Datasette""}, {""href"": ""https://github.com/simonw/datasette/issues/418"", ""label"": ""#418""}, {""href"": ""https://github.com/simonw/datasette/issues/419"", ""label"": ""#419""}, {""href"": ""https://github.com/simonw/datasette/issues/420"", ""label"": ""#420""}]" changelog:smaller-changes,changelog,smaller-changes,Smaller changes,"Datasette documentation now shows YAML examples for Metadata by default, with a tab interface for switching to JSON.

You can do this by starting it without passing any files or by using the new --memory option to datasette serve . This can be useful for experimenting with SQLite queries that do not access any data, such as SELECT 1+1 or SELECT sqlite_version() .","[""Changelog"", ""0.28 (2019-05-19)""]","[{""href"": ""https://github.com/python/black"", ""label"": ""Black coding style""}, {""href"": ""https://github.com/simonw/datasette/pull/449"", ""label"": ""#449""}, {""href"": ""https://github.com/simonw/datasette/issues/433"", ""label"": ""#433""}, {""href"": ""https://github.com/simonw/datasette/commit/583b22aa28e26c318de0189312350ab2688c90b1"", ""label"": ""583b22a""}, {""href"": ""https://github.com/simonw/datasette/commit/78e45ead4d771007c57b307edf8fc920101f8733"", ""label"": ""78e45ea""}, {""href"": ""https://github.com/simonw/datasette/issues/429"", ""label"": ""#429""}, {""href"": ""https://github.com/simonw/datasette/issues/428"", ""label"": ""#428""}, {""href"": ""https://github.com/simonw/datasette/issues/288"", ""label"": ""#288""}, {""href"": ""https://github.com/simonw/datasette/issues/435"", ""label"": ""#435""}, {""href"": ""https://github.com/simonw/datasette/issues/462"", ""label"": ""#462""}, {""href"": ""https://github.com/simonw/datasette/issues/465"", ""label"": ""#465""}]" changelog:magic-parameters-for-canned-queries,changelog,magic-parameters-for-canned-queries,Magic parameters for canned queries,"Canned queries now support Magic parameters , which can be used to insert or select automatically generated values.
