Why teams connect Apache Cassandra and HubSpot

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

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 Apache Cassandra, where it can be queried and joined like everything else.

Stacksync mirrors Deal, Line Item, Product, Ticket from HubSpot into Partitions and Rows, Materialized Views, Secondary Indexes, User-Defined Types in Apache Cassandra with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in HubSpot with validation intact. Go-to-market teams keep working in the CRM, engineers keep working in the database, and neither has to think about the other.

Common use cases

  • Write warehouse-computed lead and account scores back to HubSpot properties on a schedule or in near real time.
  • Sync HubSpot Tickets with an internal support database to unify service reporting across channels.
  • Consolidate data from multiple keyspaces or clusters into one reporting store.
  • Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Apache Cassandra sync onto the matching records in HubSpot, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the HubSpot API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in HubSpot arrive as row changes in Apache Cassandra, ready to drive jobs and notifications.

What you can sync between Apache Cassandra and HubSpot

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 HubSpot objects
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Product Synced with incremental and full sync per the Stacksync docs.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Ticket Synced with incremental and full sync per the Stacksync docs.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Quote Synced with incremental and full sync per the Stacksync docs.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Goal Synced with incremental and full sync per the Stacksync docs.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Owner Synced with incremental and full sync per the Stacksync docs.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Pipeline Synced with incremental and full sync per the Stacksync docs.

How the Apache Cassandra and HubSpot connectors work

Apache Cassandra

Integration surface
CQL over the Cassandra native binary protocol
Authentication
Database credentials (password authenticator); TLS and role-based grants where configured
Change detection
Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns
Capabilities

Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

HubSpot

Integration surface
REST API (CRM v3)
Authentication
OAuth (choose HubSpot account and authorize Stacksync); requires a HubSpot 'Super Admin' to grant access; optional "Grant access to sensitive fields" checkbox for sensitive/highly sensitive fields
Change detection
Records: incremental near-real-time change tracking. Associations: HubSpot has no native association CDC
Capabilities
