Why teams connect Cvent and DuckDB

Give your team Cvent's contacts, campaigns, and engagement in DuckDB: query them with SQL, push audiences built from your own data back to Cvent, and skip the marketing API.

Cvent holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in DuckDB, hard to get into campaigns without manual exports.

Stacksync mirrors Sessions, Speakers, Exhibitors, Surveys from Cvent into Views, External files (Parquet/CSV/JSON), Attached databases, Database files in DuckDB field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in DuckDB, from usage, orders, or account status, sync back into Cvent to drive campaigns and ads, with Cvent kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • 02 Push aggregates computed in DuckDB out to a CRM or business tools so analysis results reach operational systems.
  • 03 Write Attendees and Registrations into Cvent from external marketing signup flows, then read attendance status back into a warehouse.
  • 04 Sync Sessions and Speakers into a content database or agenda app so schedule and speaker changes propagate without manual re-entry.

Common sync patterns

Query Cvent like a database

Contacts, leads, audiences, and campaign metrics from Cvent live in DuckDB as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.

Build audiences from your own data

Segments computed in DuckDB from product usage, orders, or account status sync into Cvent as lists or audiences, so campaigns and ads target the people your data says they should.

Engagement and results next to the customer

Opens, clicks, sends, RSVPs, or ad activity from Cvent land in DuckDB beside the matching customer record, ready for reporting and revenue attribution.

What you can sync between Cvent and DuckDB

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.

Cvent objects DuckDB objects How this pairing syncs
Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Attached databases Additional database files or external systems attached into one session for cross-source queries. Surveys is specific to Cvent and Attached databases to DuckDB — each maps to any object or custom field on the other side.
Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Budgets is specific to Cvent and Database files to DuckDB — each maps to any object or custom field on the other side.
Events Top-level event containers created and updated through the Events endpoints; read out for reporting and written to provision events from an external system. Schemas Namespaces within a database used to organize tables in sync outputs. Events is specific to Cvent and Schemas to DuckDB — each maps to any object or custom field on the other side.
Contacts Account-wide people database spanning every event; synced two-way with a CRM or warehouse as the shared audience source of truth via the Create Contacts endpoint. Tables Columnar tables created via SQL; the destination for materialized sync data. Contacts is specific to Cvent and Tables to DuckDB — each maps to any object or custom field on the other side.
Attendees and Registrations Per-event registrants; written in from CRM or marketing signup flows via POST /ea/attendees and read back out to a warehouse for attendance and registration-status reporting. Views SQL views used to shape or filter data for downstream consumers. Attendees and Registrations is specific to Cvent and Views to DuckDB — each maps to any object or custom field on the other side.
Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Sessions is specific to Cvent and External files (Parquet/CSV/JSON) to DuckDB — each maps to any object or custom field on the other side.

How changes propagate between Cvent and DuckDB

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.

Cvent DuckDB Sub-second propagation

DetectionCvent notifies Stacksync of record changes through webhook events. Per-event webhooks push attendee, registration, session, and speaker changes.

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

DuckDB Cvent Interval-based propagation

DetectionStacksync polls DuckDB for changes on an incremental schedule, reading only records changed since the previous pass. Polling or full re-reads.

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

Rate-limit considerations

  • Cvent: Responses carry X-RateLimit-Limit/Remaining/Reset headers; a 429 signals either the per-second limit (retry with exponential backoff from ~2s) or the daily quota (up to 500,000 calls/day on the Premium tier, 1,000/day on Free) exhausted until midnight UTC.
  • DuckDB: No API rate limits; throughput is bounded by local compute and I/O.
