Why teams connect Citus and Cvent

Give your team Cvent's contacts, campaigns, and engagement in Citus: 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 Citus, hard to get into campaigns without manual exports.

Stacksync mirrors Budgets, Events, Contacts, Attendees and Registrations from Cvent into Local tables, Schemas, Views, Sequences in Citus 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 Citus, 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 Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • 02 Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • 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

Keep contact attributes consistent

Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.

Query Cvent like a database

Contacts, leads, audiences, and campaign metrics from Cvent live in Citus 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 Citus 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.

What you can sync between Citus and Cvent

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.

Citus objects Cvent objects How this pairing syncs
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. 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. Schemas is specific to Citus and Contacts to Cvent — each maps to any object or custom field on the other side.
Views Curated projections over distributed data, often used as read-only sync sources. 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 is specific to Citus and Attendees and Registrations to Cvent — each maps to any object or custom field on the other side.
Sequences Key generators that matter when external writes must not collide with application inserts. Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. Sequences is specific to Citus and Sessions to Cvent — each maps to any object or custom field on the other side.
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Speakers Speaker records tied to an event; synced two-way with a speaker database or CMS, with an updatedDate on each record for incremental pulls. Distributed tables is specific to Citus and Speakers to Cvent — each maps to any object or custom field on the other side.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. Reference tables is specific to Citus and Exhibitors to Cvent — each maps to any object or custom field on the other side.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Local tables is specific to Citus and Surveys to Cvent — each maps to any object or custom field on the other side.

How changes propagate between Citus and Cvent

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.

Citus Cvent Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

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

Cvent Citus 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 Citus as a row-level write, with types converted between the two schemas.

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.
