libsql virtual wal interface

[Recommended learning path from a turso engg]

We don’t have a blog post on it unfortunately. Personally I believe its one of the most impactful contributions by libsql in SQLite eco system because it opens up so many possibilities

Documentation

Its an interface, so same methods would be already implemented in sqlite, you could read those implementation

Here is the PR which added it and offers more details.

You can check bottomless code which implements WAL interface to have streaming replication to S3, like litestream.
