ClickHouse | OpenDunes Docs

Not yet available. This destination is on the roadmap.

ClickHouse is a column-oriented analytical database built for high-throughput inserts and fast aggregation queries. Sending your OpenDunes logs there gives you a fully queryable history of every LLM request — cost by model, token trends over time, latency percentiles, and more.

What gets sent#

Each request produces one row containing: request timestamp, model slug, prompt and completion token counts, DA cost in micro-DA, latency in milliseconds, the input messages as JSON, the response content, X-Request-Id, and any custom metadata from the request.

Configuration#

Once available, configure the ClickHouse destination from your dashboard under Broadcast. You will need:

Host — your ClickHouse host (e.g. https://abc123.us-east-1.aws.clickhouse.cloud)
Port — typically 8443 for HTTPS
Database — the target database name
Table — the target table; OpenDunes will create it if it does not exist
Username / Password — ClickHouse credentials with INSERT rights

The broadcast worker batches inserts to minimise write amplification; you can expect rows to land within a few seconds of the request completing.
