Why teams connect Anthropic and ClickHouse

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

Anthropic 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 Anthropic — without exports, scripts, or schedulers.

ClickHouse holds the raw records the business runs on; Anthropic 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 Pull the Usage Report into a warehouse to attribute Claude token spend by workspace, model, and API key for internal chargeback.
  • 02 Sync the Cost Report into a finance database or FinOps tool for daily AI-spend reporting alongside other vendor costs.
  • 03 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 04 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.

Common sync patterns

Model output back in the warehouse

Scores, labels, embeddings, or summaries produced in Anthropic land in ClickHouse as columns or tables, queryable and joinable with the rest of the business data.

Keep an index in step with the source

As records change in ClickHouse, matching API Keys, Invites, Message Batches, Models in Anthropic are inserted, updated, or removed, so what Anthropic serves reflects the warehouse instead of a stale snapshot.

One place to analyze AI results

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

What you can sync between Anthropic and ClickHouse

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.

Anthropic objects ClickHouse objects How this pairing syncs
Workspaces Organization workspaces from the Admin API (/v1/organizations/workspaces); synced read-mostly so usage, keys, and members can be mapped to the workspace they belong to. Databases Namespaces that group tables and scope permissions for sync users. Workspaces is specific to Anthropic and Databases to ClickHouse — each maps to any object or custom field on the other side.
Organization Members Users in the organization with their role from /v1/organizations/users; read into an IdP or HR database for access auditing rather than written back. Views Saved queries used as curated, read-only sync sources. Organization Members is specific to Anthropic and Views to ClickHouse — each maps to any object or custom field on the other side.
API Keys Key metadata — name, owning workspace, status, creator — from /v1/organizations/api_keys; the secret value is never returned. Read-only, useful for a security key inventory. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. API Keys is specific to Anthropic and Materialized views to ClickHouse — each maps to any object or custom field on the other side.
Invites Pending organization invitations from /v1/organizations/invites; read to track who has been invited to the org but has not yet accepted. Distributed tables Query-routing tables over cluster shards in self-managed deployments. Invites is specific to Anthropic and Distributed tables to ClickHouse — each maps to any object or custom field on the other side.
Message Batches Asynchronous batch jobs at /v1/messages/batches; the connector polls processing_status and reads per-request results keyed by custom_id once a batch has ended. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Message Batches is specific to Anthropic and Dictionaries to ClickHouse — each maps to any object or custom field on the other side.
Models Claude model catalog from /v1/models with model IDs, context window, max output, and capability flags; snapshotted into a config table so applications avoid hardcoding model IDs. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Models is specific to Anthropic and Tables (MergeTree family) to ClickHouse — each maps to any object or custom field on the other side.

How changes propagate between Anthropic and ClickHouse

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.

Anthropic ClickHouse Interval-based propagation

DetectionStacksync polls Anthropic for changes on an incremental schedule, reading only records changed since the previous pass. Polling.

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

ClickHouse Anthropic 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.

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

Rate-limit considerations

  • Anthropic: Messages API limits are per usage tier: requests-per-minute plus input- and output-tokens-per-minute, surfaced in anthropic-ratelimit-* response headers with retry-after on 429. Usage/cost reports recommend polling at most once per minute.

How the Anthropic and ClickHouse connectors work

Anthropic

Integration surface
REST — Messages API at api.anthropic.com/v1 plus the Admin API (/v1/organizations/*) for organization, usage, and cost data
Authentication
API key in the x-api-key header for Messages, Models, Files, and Batches endpoints; the Admin API requires a separate Admin API key (sk-ant-admin...) with organization-admin permission. Every request also sends an anthropic-version header.
Change detection
Polling. Usage and cost reports are queried by time bucket (1m/1h/1d) over a date range; list endpoints paginate with has_more/next_page (or after_id). No general-purpose data-change webhooks (webhooks exist only for Managed Agents session state).
Capabilities

Rate limits
Messages API limits are per usage tier: requests-per-minute plus input- and output-tokens-per-minute, surfaced in anthropic-ratelimit-* response headers with retry-after on 429. Usage/cost reports recommend polling at most once per minute.

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
