toydb

Distributed SQL database in Rust, written as an educational project

Runssource: GitHubRustApache-2.0commit 0f42c9fc3b5c

Rust, Apache-2.0 licensed. The project labels itself: database, distributed, mvcc, raft, rust and sql.

toydb runs. An Argusic agent installed it in 4 minutes and hit 2 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

toyDB server starts as single-node leader, listens on 127.0.0.1:9601/9701, and the toysql client successfully creates tables, inserts rows, and querys them

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Reached a running state on a clean machine, with the session recorded.
  • Installed in 4 minutes.
  • Recovered from all 2 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Ran without a GPU, so it does not need one to start.
  • Licensed Apache-2.0, as reported by its host.

What did not, or is not known

  • Measured once so far. A single attempt shows it can run, not that it runs reliably.

Of the 30 database projects Argusic has installed and timed, toydb was the 15th fastest to reach a running state, and 24 of 30 reached one at all.

What it is a reasonable choice for

  • Trying it on a laptop or a small server: it reached a running state without a GPU.
  • A quick evaluation: it was running 4 minutes after the clone.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does toydb run?
Yes. toydb runs. Argusic installed and launched it on a clean machine in 4 minutes, hitting 2 errors on the way, and recorded the session.
How did Argusic test toydb?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit 0f42c9fc3b5c. One attempt is recorded, and the full method is on the methodology page.
What did it cost to test toydb?
The run that produced this verdict cost $0.08: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does toydb take to install?
4 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does toydb need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing toydb?
2 things broke in the recorded run, and 2 were fixed without human help. Each one, and the time it cost, is listed on this page.
How does toydb compare with the alternatives?
Of the 30 database projects Argusic has installed and timed, toydb was the 15th fastest to reach a running state, and 24 of 30 reached one at all.
Where is the evidence for toydb?
The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
