101: Replicating SQLite using Litestream with Ben Johnson Thinking Elixir Podcast

Ben Johnson explains his project Litestream.io, an OpenSource tool that replicates SQLite databases to remote servers and to backup locations like S3 for durability. We talk about how moving data out to the user creates true edge applications. We discuss what types of problems this helps solve, the architectures that become possible, and how a globally distributed Phoenix application could use this. He shares how Fly.io acquired the project and brought him on full-time to continue his work on it. Fascinating discussion that challenges many of the assumptions about how we've been building “web” systems for years.
