Why teams connect Crustdata and SQL Server

Treat Crustdata like part of your database: its records live in SQL Server as real tables, and writes in either place sync to the other in seconds.

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

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in SQL Server, where it can be queried and joined like everything else.

Common use cases

  • 01 Enrich CRM accounts with firmographics, headcount growth, and tech stack so scoring and routing run on complete data.
  • 02 Fill missing contact fields on CRM people records from Crustdata profiles instead of manual research.
  • 03 Feed a cloud warehouse from SQL Server continuously using native CDC instead of SSIS batch jobs
  • 04 Consolidate branch or plant databases into a single operational SQL Server hub

Common sync patterns

Trigger workflows from CRM changes

Field and stage updates in Crustdata arrive as row changes in SQL Server, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Crustdata become tables in SQL Server you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to SQL Server sync onto the matching records in Crustdata, giving go-to-market teams live product context.

What you can sync between Crustdata and SQL Server

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.

Crustdata objects SQL Server objects How this pairing syncs
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. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers. Enrichment Responses is specific to Crustdata and CDC Change Tables to SQL Server — each maps to any object or custom field on the other side.
Companies Firmographic records — industry, size, funding, growth signals; read out to enrich CRM accounts and warehouse company tables. Stored Procedures T-SQL logic that can validate or post-process synced rows. Companies is specific to Crustdata and Stored Procedures to SQL Server — each maps to any object or custom field on the other side.
People Contact and profile data for decision-makers; read into a CRM or outreach tool to fill missing titles, emails, and LinkedIn profiles. Databases Instance-level databases that scope a sync's reads and writes. People is specific to Crustdata and Databases to SQL Server — each maps to any object or custom field on the other side.
Headcount and Growth Metrics Time-series employee counts by department and region; read to score accounts on hiring momentum and expansion signals. Schemas Namespaces (dbo and custom) used to organize synced tables. Headcount and Growth Metrics is specific to Crustdata and Schemas to SQL Server — each maps to any object or custom field on the other side.
Tech Stack Detected technologies per company; read to build segments and route accounts by the tools they already use. Tables The primary sync target; rows map to records in connected systems. Tech Stack is specific to Crustdata and Tables to SQL Server — each maps to any object or custom field on the other side.
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. Views Read-side projections used as outbound sync sources. Screener Results is specific to Crustdata and Views to SQL Server — each maps to any object or custom field on the other side.

How changes propagate between Crustdata and SQL Server

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.

Crustdata SQL Server 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 SQL Server as a row-level write, with types converted between the two schemas.

SQL Server Crustdata Sub-second propagation

DetectionChanges in SQL Server are captured at the source via change data capture — no polling loop against its API. SQL Server Native Change Data Capture (CDC).

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 SQL Server records.

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.
  • SQL Server: No API rate limits; throughput depends on instance resources, licensing tier, and connection limits.
