Why teams connect Apache Cassandra and Outreach

Treat Outreach 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 Sequences, Sequence states, Mailings, Calls from Outreach into Tables, Partitions and Rows, Materialized Views, Secondary Indexes in Apache Cassandra with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Outreach 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

  • Keep account ownership and stages aligned between Outreach and the CRM as territories change.
  • Suppress prospects across systems when a contact unsubscribes or a customer churns.
  • Feed Cassandra change streams into search indexes or caches that must track the source of truth.
  • Consolidate data from multiple keyspaces or clusters into one reporting store.

Query the CRM like a database

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

Product events onto CRM records

Signup, usage, or lifecycle changes written to Apache Cassandra sync onto the matching records in Outreach, 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 Outreach API, limits, and retries.

What you can sync between Apache Cassandra and Outreach

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 Outreach objects
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Calls Logged call records synced into engagement reporting
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Tasks Rep action items mirrored between Outreach and the CRM
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Opportunities Deal records used to tie engagement to pipeline outcomes
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Users Seat holders used to resolve ownership on synced records
Collections List, set, and map columns handled with type-aware field mapping. Mailboxes Connected sending accounts referenced when attributing outbound activity
Counters Increment-only counter columns, usually read-only in syncs. Prospects The people being engaged; the main record kept in sync with the CRM
