Why teams connect ClickHouse and Openai

Flow Openai data into ClickHouse in real time — no exports, no schedulers, no custom scripts.

Openai is a read-only source: Stacksync reads its data in real time and delivers it into ClickHouse, so ClickHouse always reflects the current state of Openai — without exports, scripts, or schedulers.

ClickHouse holds the raw records the business runs on; Openai turns those records into embeddings, scores, labels, and summaries. The two meet wherever a warehouse row needs to be enriched by a model and the result needs somewhere durable to live. Most teams stitch that meeting together with export scripts and a queue, then spend their time keeping the glue alive.

The payoff is that model output stops living in a separate place from the data it describes. Once results sit in ClickHouse, they join against billing, product, and usage tables already there, so you can report on quality, cost, and coverage without moving anything by hand.

Common use cases

  • 01 Subscribe to batch.completed and fine_tuning.job.succeeded webhooks so a downstream pipeline step fires the moment an offline-inference or training job finishes.
  • 02 Pull Administration Usage and Costs into a warehouse for FinOps chargeback, per-project budget tracking, and spend-tier planning.
  • 03 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • 04 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.

Common sync patterns

One place to analyze AI results

Combine Openai's output with the tables already in ClickHouse to report on model quality, cost, and coverage without exporting anything to a spreadsheet.

History that outlives a run

A continuously synced copy in ClickHouse preserves every generated result, so outputs stay auditable even as they are overwritten or expire inside Openai.

Feed live warehouse records to Openai

Rows added or changed in ClickHouse flow into Openai within seconds, so embeddings, classifications, and enrichments are computed on current data rather than a nightly extract.

What you can sync between ClickHouse and Openai

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

ClickHouse objects Openai objects How this pairing syncs
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Vector stores File collections backing file-search retrieval, with name, file counts, usage bytes, and status; read as a metadata inventory of retrieval assets. Dictionaries is specific to ClickHouse and Vector stores to Openai — each maps to any object or custom field on the other side.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Usage & Costs Per-model and per-project token, request, and dollar figures from the Administration Usage and Costs endpoints, read for FinOps chargeback and spend reporting. Tables (MergeTree family) is specific to ClickHouse and Usage & Costs to Openai — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Projects & Members Organization projects, their members, and service accounts from the Administration API; read as an access-and-ownership inventory. Databases is specific to ClickHouse and Projects & Members to Openai — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Audit logs Organization audit-log events (API-key changes, logins, project edits) from the Administration API; read for compliance and security monitoring. Views is specific to ClickHouse and Audit logs to Openai — each maps to any object or custom field on the other side.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Models Catalog of available base, snapshot, and fine-tuned models with owner and capabilities; read-only reference data used to resolve inference and fine-tuning targets. Materialized views is specific to ClickHouse and Models to Openai — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Fine-tuning jobs Training jobs with status, base model, hyperparameters, trained-model name, and result files; status received by webhook or polled from queued through succeeded or failed. Distributed tables is specific to ClickHouse and Fine-tuning jobs to Openai — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Openai

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

ClickHouse Openai Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

DeliveryOpenai does not accept inbound record writes, so this direction carries requests rather than records: Openai's output flows back as field updates on the originating ClickHouse records.

Openai ClickHouse Sub-second propagation

DetectionOpenai notifies Stacksync of record changes through webhook events. Push webhooks (Standard Webhooks spec, whsec_ signing secret) fire on batch.completed, fine_tuning.job.succeeded/failed, response.completed/failed,.

DeliveryEach detected change is applied to ClickHouse as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Openai: Rate limits are set per organization and per project as RPM/RPD and TPM/TPD and rise across five spend-based usage tiers; responses carry x-ratelimit-remaining headers and return HTTP 429 on breach.

How the ClickHouse and Openai connectors work

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
Capabilities
read · write

Openai

Integration surface
REST API: data-plane inference and authoring (api.openai.com/v1) plus the Administration API (/v1/organization/*) for usage, costs, projects, and audit logs
Authentication
Bearer API key scoped to a project or user (sk-...) in the Authorization header, with optional OpenAI-Organization and OpenAI-Project headers; the Administration API requires an Admin key (sk-admin-...)
Change detection
Push webhooks (Standard Webhooks spec, whsec_ signing secret) fire on batch.completed, fine_tuning.job.succeeded/failed, response.completed/failed, and eval.run events; objects without a webhook are read by list plus GET-by-ID. No row-level CDC feed.
