Releasing Fjall 3.0

I'm using fjall v2 in the Rust event streaming store, cross.stream. xs is for personal scale so fjall is fairly overkill performance-wise. marvin_j97's benchmark work and deep dives into different database systems is incredible though. Looking forward to updating to v3.

I was looking for something like https://github.com/fjall-rs/sfa, how nice!

Not sure if the author is reading but the three hues of blue you use for fjall v2 vs fjall v3 vs rusqlite in the benchmark graphs are very hard (at least for me) to visually distinguish.

I'm trying to compare with redb which is currently my goto for small Rust applications.

• both have tables/keyspaces as logicalally separate maps
• both can do single-writer, but fjall has support for multi-writter and optimistic transactions
• redb supports more of a mmap-based interface, so values don't necessarily need to be serialized to a Vec<u8> (which personally I don't use, but it is there)
• one could write a custom backend for redb https://docs.rs/redb/latest/redb/struct.Builder.html#method.create_with_backend which is nice

Is anyone aware if fjall has any wasm support?

Oh this is amazing. I have been eyeing this for weeks now to help back some of my hobby project ideas.
