Litestream VFS

I work with many distributed, often offline, hosts with varied levels of internet speeds. Does this do any offline caching? Like if I load a vfs litestream database on one of my nodes and it goes offline can it still query or will it fall over unless the data was recently fetched?

Author here. It will cache pages in memory right now but it doesn't do disk-based caching currently. That's a good idea though and probably not too difficult to implement. Feel free to post a feature request as a GitHub issue on the project.
