Low level database access?

[andy-thomason]

It would be very useful to be able to access the database from an external process such as in the following example:

fn access_database() -> anyhow::Result<()> {
    let path = Path::new("/data/fuel/data/fuel_beta5");
    let database = Database::open(path, None)?;

    let h = database.latest_height()?;
    println!("h={h}");
    Ok(())
}

We can do this with many blockchain nodes without stopping the service
and it provides a low-latency, high-throughput interface to the state of the node.
But it seems that the rocksdb database has a permanent lock on the LOCK file.

Perhaps there is something I don't understand or an alternative table-level interface
such as Erigon's KV gRPC (not ideal, but better than GraphQL).

If I am being an idiot, please say so!
