Introducing datasette-litestream: easy replication for SQLite databases in Datasette. We use Litestream on Datasette Cloud for streaming backups of user data to S3. Alex Garcia extracted out our implementation into a standalone Datasette plugin, which bundles the Litestream Go binary (for the relevant platform) in the package you get when you run “datasette install datasette-litestream”—so now Datasette has a very robust answer to questions about SQLite disaster recovery beyond just the Datasette Cloud platform. # 13th September 2023, 7:28 pm

Stringing together several free tiers to host an application with zero cost using fly.io, Litestream and Cloudflare. Alexander Dahl provides a detailed description (and code) for his current preferred free hosting solution for small sites: SQLite (and a Go application) running on Fly’s free tier, with the database replicated up to Cloudflare’s R2 object storage (again on a free tier) by Litestream. # 7th October 2022, 5:47 pm
Introducing LiteFS (via) LiteFS is the new SQLite replication solution from Fly, now ready for beta testing. It’s from the same author as Litestream but has a very different architecture; LiteFS works by implementing a custom FUSE filesystem which spies on SQLite transactions being written to the journal file and forwards them on to other nodes in the cluster, providing full read-replication. The signature Litestream feature of streaming a backup to S3 should be coming within the next few months. # 21st September 2022, 6:56 pm
Litestream backups for Datasette Cloud (and weeknotes)
My main focus this week has been adding robust backups to the forthcoming Datasette Cloud.
[... 1604 words]Litestream: Live Read Replication (via) The documentation for the read replication implemented in the latest Litestream beta (v0.4.0-beta.2). The design is really simple and clever: the primary runs a web server on a port, and replica instances can then be started with a configured URL pointing to the IP and port of the primary. That’s all it takes to have a SQLite database replicated to multiple hosts, each of which can then conduct read queries against their local copies. # 13th April 2022, 2:04 am
SQLite Happy Hour—a Twitter Spaces conversation about three interesting projects building on SQLite
Yesterday I hosted SQLite Happy Hour. my first conversation using Twitter Spaces. The idea was to dig into three different projects that were doing interesting things on top of SQLite. I think it worked pretty well, and I’m curious to explore this format more in the future.

logpaste (via) Useful example of how to use the Litestream SQLite replication tool in a Dockerized application: S3 credentials are passed to the container on startup, it then attempts to restore the SQLite database from S3 and starts a Litestream process in the same container to periodically synchronize changes back up to the S3 bucket. # 17th March 2021, 3:48 pm
Litestream runs continuously on a test server with generated load and streams backups to S3. It uses physical replication so it’ll actually restore the data from S3 periodically and compare the checksum byte-for-byte with the current database.

trustme (via) This looks incredibly useful. Run “python -m trustme” and it will create three files for you: server.pem, server.key and a client.pem client certificate, providing a certificate for “localhost” (or another host you spefict) using a fake certificate authority. Looks like it should be the easiest way to test TLS locally. # 11th February 2021, 8 pm
