That’s fair, the number alone doesn’t mean much without context.

The benchmark measures fully written time-series records, not bytes. Each record typically includes 1–4 fields, tags, and timestamps, similar to InfluxDB’s Line Protocol structure.

For comparison, the same hardware (AWS c6a.4xlarge) handles around 240K RPS using Line Protocol, while Arc reaches 1.88M RPS with MessagePack, about 7.8× faster on ingestion throughput.

You can see the full ClickBench and ingestion benchmarks are in the repo.

TL;DR: Arc’s strength isn’t massive single records, it’s sustained high-throughput ingestion of structured time-series data while still staying analytical-query friendly.
