Why teams connect Clari and ClickHouse

Sync Clari into ClickHouse continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Opportunity field extensions, Audit Events, Forecast, Quota from Clari land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Clari. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Stream Audit Events into a reporting database to monitor forecast-submission changes and user activity for compliance.
  • 02 Pull Activity (Capture) meetings and emails, mapped to their accounts and opportunities, into a database for coverage and engagement analysis.
  • 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

A single customer view

Join Clari's relationship data with billing, product, and support data in ClickHouse to build the customer picture the CRM alone cannot hold.

Cleanup that sticks

Deduplication and normalization done in ClickHouse can be written back, so warehouse-side cleanup actually fixes the CRM.

CRM analytics on live data

Accounts, contacts, and activity from Clari are queryable in ClickHouse moments after they change, so dashboards stop lagging the reality they describe.

What you can sync between Clari 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.

Clari objects ClickHouse objects How this pairing syncs
Activity (Capture) Meetings, emails, and attachments captured by Clari and mapped to accounts and opportunities; exported read-only via async activity jobs. Views Saved queries used as curated, read-only sync sources. Activity (Capture) is specific to Clari and Views to ClickHouse — each maps to any object or custom field on the other side.
Account field extensions External data points written onto Account records through the ingest API in initial or incremental mode; requires an apikey plus a partnerkey. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Account field extensions is specific to Clari and Materialized views to ClickHouse — each maps to any object or custom field on the other side.
Opportunity field extensions Warehouse-computed fields pushed onto Opportunity records via the ingest API; up to 100 records per request or 10MB bulk files. Distributed tables Query-routing tables over cluster shards in self-managed deployments. Opportunity field extensions is specific to Clari and Distributed tables to ClickHouse — each maps to any object or custom field on the other side.
Audit Events User edits and system events exported with filtering by actor, session, and date range; read-only feed for change tracking and compliance. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Audit Events is specific to Clari and Dictionaries to ClickHouse — each maps to any object or custom field on the other side.
Forecast Exported per forecast tab and fiscal period via async jobs; includes submitted forecast calls, updates, manager adjustments, and CRM totals. Read-only. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Forecast is specific to Clari and Tables (MergeTree family) to ClickHouse — each maps to any object or custom field on the other side.
Quota Quota and quota-history values exported alongside forecast data, scoped by fiscal quarter; read-only, useful for warehouse attainment reporting. Databases Namespaces that group tables and scope permissions for sync users. Quota is specific to Clari and Databases to ClickHouse — each maps to any object or custom field on the other side.

How changes propagate between Clari 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.

Clari ClickHouse Interval-based propagation

DetectionStacksync polls Clari for changes on an incremental schedule, reading only records changed since the previous pass. Polling — reads run as asynchronous export jobs (submit export, poll job status, download results).

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

ClickHouse Clari 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.

DeliveryEach detected change is written to Clari through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Clari: Max 3 concurrent exports and roughly 1000 exports per rolling 30-day org window; ingestion capped at 100 requests/sec per API token.

How the Clari and ClickHouse connectors work

Clari

Integration surface
REST APIs on api.clari.com - Export API (v4, asynchronous bulk jobs for forecast, quota, activity, and audit) and Ingest API (v2, field extensions); Opportunity reads are synchronous via GET /opportunity
Authentication
API token in the apikey header, generated per user in Settings; ingest/partner endpoints also require a partnerkey header, and Copilot endpoints require X-Api-Key and X-Api-Password
Change detection
Polling — reads run as asynchronous export jobs (submit export, poll job status, download results); the ingest API supports an incremental mode for regular field updates. No webhooks.
Capabilities
read · write
Rate limits
Max 3 concurrent exports and roughly 1000 exports per rolling 30-day org window; ingestion capped at 100 requests/sec per API token.

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
