tsink
A lightweight time-series database written in Rust. Embed it, run it as a server, or scale it as a cluster.
Runssource: GitHubRustMITcommit 277e7449a1df
Rust, MIT licensed. The project labels itself: database, embedded database, rust, time series, timeseries, timeseries database and tsdb.
tsink runs. An Argusic agent installed it in 27 minutes and hit 2 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
The tsink time-series database builds, all 1235 tests pass, and the server binary starts, serves /healthz (200), /ready (200), /metrics (Prometheus stats), accepts Prometheus text exposition writes, and returns correct PromQL query results.
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.
- Rust toolchain not found in container1 minute
- 3 flaky tests in tsink-server crate fail in parallel mode (port/race-condition in test harness)
- Install time
- 27 minutes
- Cold machine to finish
- 29 minutes
- Errors hit and fixed
- 2 hit, 2 fixed with no human help
- How the result was proved
- cargo test --workspace -- --test-threads=1: 1235 passed, 0 failed, 2 ignored. Then started tsink-server on :9202 and exercised: GET /healthz -> 200 'ok', GET /ready -> 200 'ready', POST /api/v1/import/prometheus with current-timestamp data point returned no error, GET /api/v1/query?query=http_requests_total returned the written data point correctly, GET /metrics returned Prometheus-format self-instrumentation.

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
Watch the session
The whole run, from a clean machine, at the speed it actually happened. Nothing is cut and nothing is sped up.
A recording of attempt 1, run . The verdict above comes from a different attempt, so read this as one session and not as the current result. The terminal recording it was made from is the evidence, stored with a sha256 fingerprint; the video is a rendering of it. Nothing loads from the video host until you press play.
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.

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.
- 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 MIT, as reported by its host.
- Measured 2 times, so the result is not a one-off.
What did not, or is not known
- Took 27 minutes to install, slower than the median of the 13 comparable projects Argusic has measured.
Of the 14 database projects Argusic has installed and timed, tsink was the 14th fastest to reach a running state, and 13 of 14 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.
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.

[](https://argusic.com/subject/tsink)Questions
- Does tsink run?
- Yes. tsink runs. Argusic installed and launched it on a clean machine in 27 minutes, hitting 2 errors on the way, and recorded the session.
- How did Argusic test tsink?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 277e7449a1df. 2 attempts are recorded, and the full method is on the methodology page.
- What did it cost to test tsink?
- 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 tsink take to install?
- 27 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 tsink need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing tsink?
- 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 tsink compare with the alternatives?
- Of the 14 database projects Argusic has installed and timed, tsink was the 14th fastest to reach a running state, and 13 of 14 reached one at all.
- Where is the evidence for tsink?
- All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
