Why teams connect Affinity and Apache Cassandra

Treat Affinity 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 List Entries, Persons, Organizations, Opportunities from Affinity into User-Defined Types, Collections, Counters, Keyspaces in Apache Cassandra with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Affinity 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

  • Push enrichment data computed elsewhere into Affinity field values on list entries.
  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.

Internal tools without API code

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

Trigger workflows from CRM changes

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

Query the CRM like a database

Accounts, contacts, and custom objects from Affinity become tables in Apache Cassandra you can join with application data directly.

What you can sync between Affinity and Apache Cassandra

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.

Affinity objects Apache Cassandra objects
Interactions Automatically captured emails and meetings, read for activity reporting. Counters Increment-only counter columns, usually read-only in syncs.
Reminders Follow-up tasks associated with people and organizations. Keyspaces Top-level namespaces with replication settings that scope a sync connection.
Lists Pipelines (deal flow, fundraising, portfolio) that structure most Affinity data; syncs usually target a specific list. Tables Wide-column tables addressed by partition key, the unit of row-level sync.
List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. Partitions and Rows Records located by partition and clustering keys during reads and upserts.
Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases.
Organizations Company records matched to accounts in other systems by domain. Secondary Indexes Optional indexes that allow filtered reads outside the partition key.
