Why teams connect Apache Cassandra and Demandbase

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

Demandbase 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 People (Persons), Activities, Campaigns, Account & Person Lists (Audiences) from Demandbase into User-Defined Types, Collections, Counters, Keyspaces 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 Demandbase to drive campaigns and ads, with Demandbase kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • 02 Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • 03 Enrich CRM Company and Contact records with Demandbase firmographics, technographics, and verified business emails through the B2B Company and Contact Details endpoints.
  • 04 Sync Opportunities and Activities two-way so CRM deal and engagement data flows into Demandbase reporting and Demandbase-calculated insights flow back to the warehouse.

Common sync patterns

Build audiences from your own data

Segments computed in Apache Cassandra from product usage, orders, or account status sync into Demandbase 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 Demandbase land in Apache Cassandra beside the matching customer record, ready for reporting and revenue attribution.

React to marketing changes as row changes

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

What you can sync between Apache Cassandra and Demandbase

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 Demandbase objects How this pairing syncs
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Accounts Company/account records with firmographics, intent, and Demandbase qualification and engagement scores; exported via the Data Export API and imported or updated via the Data Import API. Keyspaces is specific to Apache Cassandra and Accounts to Demandbase — 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. Opportunities Opportunity records synced from the CRM into Demandbase; exported with calculated insights and imported or updated through the Data Import API. Read and write. Tables is specific to Apache Cassandra and Opportunities to Demandbase — each maps to any object or custom field on the other side.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. People (Persons) Contact/person records with verified business email, title, seniority, and quality grades; fetched and matched via the B2B Contact endpoints and exported or imported. Partitions and Rows is specific to Apache Cassandra and People (Persons) to Demandbase — each maps to any object or custom field on the other side.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Activities Engagement and custom activity records (web, campaign, intent); exported via Data Export and pushed in through the Data Import API using custom activity types. Materialized Views is specific to Apache Cassandra and Activities to Demandbase — each maps to any object or custom field on the other side.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Campaigns Marketing campaign records and creative assets exported through the Data Export API; read-only reporting feed. Secondary Indexes is specific to Apache Cassandra and Campaigns to Demandbase — 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. Account & Person Lists (Audiences) Named account and person segments exported via Data Export; custom audiences pushed into Demandbase through the Data Import API. Read and write. User-Defined Types is specific to Apache Cassandra and Account & Person Lists (Audiences) to Demandbase — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra and Demandbase

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 Demandbase 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 Demandbase through its API, with automatic retries and rate-limit backoff.

Demandbase Apache Cassandra Sub-second propagation

DetectionDemandbase notifies Stacksync of record changes through webhook events. Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL.

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.
  • Demandbase: Credit-based per API call; bulk jobs accept up to 10,000 records per submission, CSV uploads up to 5GB, and result URLs stay valid 24 hours; subscription alerts page up to 5,000 entities and list endpoints up to 100 per page.
