Bitrust
This is a Rust implementation of Bitcask, a persistent key-value store for when the keyspace fits in memory. This is not a distributed datastore, but can be used as a building block for one.
This crate hasn't been stress-tested. While it should be good enough for experimentation, we make no guarantees around data durability.
Running
$ mkdir /tmp/bitrust_data
$ cargo run -- --configfile ./example_configs/no-automerge.toml --loglevel debug
> put foo bar
> get foo
Ok(Some("bar"))
> put baz spam
> put lala baba
> put baz egg
> lst
lala
foo
baz
> get baz
Ok(Some("egg"))
> quit
$ less /tmp/bitrust_data/bitrust.log
You can view the logs in a separate window by tailing bitrust.log
in the
datadir.
$ tail -f /tmp/bitrust_data/bitrust.log
