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

```shell $ mkdir /tmp/bitrustdata $ cargo run -- --configfile ./exampleconfigs/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

Data directory contents

• Data files are stored as N.data where N is an integer starting at 0.
• .activefile contains the name of the current "active" log file (i.e., the one taking writes). All other datafiles are immutable.
• bitrust.log contains logs. Level of logging is controlled by the -l/--loglevel switch.
