toyDB

toyDB is a distributed SQL database in Rust, built from scratch as an educational project. Main features:

• Raft distributed consensus for linearizable state machine replication.

• ACID transactions with MVCC-based snapshot isolation.

• Pluggable storage engine with BitCask and in-memory backends.

• Iterator-based query engine with heuristic optimization and time-travel support.

• SQL interface including joins, aggregates, and transactions.

toyDB is not distributed as a crate, see https://github.com/erikgrinaker/toydb for more.

This crate used to contain the joydb database. Thanks to Serhii Potapov for donating the crate name.
