Why teams connect ClickHouse and Crustdata

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

Crustdata 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 Crustdata — without exports, scripts, or schedulers.

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. Tech Stack, Screener Results, Enrichment Responses, Companies from Crustdata land in ClickHouse as live tables, updated within seconds, and columns computed in ClickHouse write back to fields in Crustdata. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • 01 Append enrichment at lead-capture time so new records arrive scored and routable.
  • 02 Enrich CRM accounts with firmographics, headcount growth, and tech stack so scoring and routing run on complete data.
  • 03 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 04 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

Common sync patterns

CRM analytics on live data

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

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in ClickHouse appear as fields in Crustdata, where the people working accounts actually see them.

A single customer view

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

What you can sync between ClickHouse and Crustdata

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 Crustdata objects How this pairing syncs
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Enrichment Responses Real-time enrichment lookups keyed by domain or profile URL; read to append fresh firmographic and contact data at form-fill or record-creation time. Distributed tables is specific to ClickHouse and Enrichment Responses to Crustdata — each maps to any object or custom field on the other side.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Companies Firmographic records — industry, size, funding, growth signals; read out to enrich CRM accounts and warehouse company tables. Dictionaries is specific to ClickHouse and Companies to Crustdata — 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. People Contact and profile data for decision-makers; read into a CRM or outreach tool to fill missing titles, emails, and LinkedIn profiles. Tables (MergeTree family) is specific to ClickHouse and People to Crustdata — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Headcount and Growth Metrics Time-series employee counts by department and region; read to score accounts on hiring momentum and expansion signals. Databases is specific to ClickHouse and Headcount and Growth Metrics to Crustdata — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Tech Stack Detected technologies per company; read to build segments and route accounts by the tools they already use. Views is specific to ClickHouse and Tech Stack to Crustdata — each maps to any object or custom field on the other side.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Screener Results Saved company searches with filter criteria; read on a schedule so target-account lists in the CRM refresh as companies enter the criteria. Materialized views is specific to ClickHouse and Screener Results to Crustdata — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and Crustdata

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 Crustdata 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.

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

Crustdata ClickHouse Interval-based propagation

DetectionStacksync polls Crustdata for changes on an incremental schedule, reading only records changed since the previous pass. Pull-based: real-time enrichment endpoints for on-demand lookups plus periodic re-pulls of screeners and datasets.

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

Rate-limit considerations

  • Crustdata: Requests are metered by plan credits and per-minute rate limits; bulk dataset pulls are the efficient path for large refreshes rather than per-record enrichment calls.
