Why teams connect Apache Cassandra and Cvent

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

Stacksync mirrors Attendees and Registrations, Sessions, Speakers, Exhibitors from Cvent into Tables, Partitions and Rows, Materialized Views, Secondary Indexes in Apache Cassandra 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 Apache Cassandra, 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 Consolidate data from multiple keyspaces or clusters into one reporting store.
  • 02 Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • 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

React to marketing changes as row changes

A new lead, form fill, or list change in Cvent arrives as a row change in Apache Cassandra, so scoring, jobs, and notifications run in the tooling your team already uses.

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 Apache Cassandra as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.

What you can sync between Apache Cassandra 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.

Apache Cassandra objects Cvent objects How this pairing syncs
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. 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. Secondary Indexes is specific to Apache Cassandra and Attendees and Registrations to Cvent — each maps to any object or custom field on the other side.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Sessions Agenda items within an event; listed or created through the API and synced so session-level attendance feeds reporting tables. User-Defined Types is specific to Apache Cassandra and Sessions to Cvent — each maps to any object or custom field on the other side.
Collections List, set, and map columns handled with type-aware field mapping. 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. Collections is specific to Apache Cassandra and Speakers to Cvent — each maps to any object or custom field on the other side.
Counters Increment-only counter columns, usually read-only in syncs. Exhibitors Exhibitor and sponsor records; synced to a CRM or database to track booth, sponsorship, and lead-capture data per event. Counters is specific to Apache Cassandra and Exhibitors to Cvent — each maps to any object or custom field on the other side.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Surveys Survey definitions and responses; read out to a warehouse for post-event feedback analysis alongside attendance data. Keyspaces is specific to Apache Cassandra and Surveys to Cvent — each maps to any object or custom field on the other side.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Budgets Event budget line items; read into a finance database or ERP to reconcile planned versus actual event spend. Tables is specific to Apache Cassandra and Budgets to Cvent — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra 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.

Apache Cassandra Cvent Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

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

Cvent Apache Cassandra 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 written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
  • 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.
