Why teams connect Apache Cassandra and Seismic

Treat Seismic 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 Digital Sales Rooms, Reporting Activities, Library Content, Content Versions from Seismic into Counters, Keyspaces, Tables, Partitions and Rows in Apache Cassandra with real-time, bi-directional sync. Read CRM records with plain queries; write updates from your application and they appear in Seismic 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

  • 01 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 02 Provision and deactivate Seismic Users and User Groups from an HRIS or IdP so content access mirrors joiner, mover, and leaver changes.
  • 03 Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • 04 Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.

Common sync patterns

Trigger workflows from CRM changes

Field and stage updates in Seismic 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 Seismic 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 Seismic, giving go-to-market teams live product context.

What you can sync between Apache Cassandra and Seismic

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 Seismic objects How this pairing syncs
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Tables is specific to Apache Cassandra and Library Content to Seismic — 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. Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Partitions and Rows is specific to Apache Cassandra and Content Versions to Seismic — 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. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Materialized Views is specific to Apache Cassandra and Users to Seismic — each maps to any object or custom field on the other side.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Secondary Indexes is specific to Apache Cassandra and User Groups to Seismic — 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. Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. User-Defined Types is specific to Apache Cassandra and Teamsites to Seismic — each maps to any object or custom field on the other side.
Collections List, set, and map columns handled with type-aware field mapping. LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. Collections is specific to Apache Cassandra and LiveSend Links to Seismic — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra and Seismic

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

Seismic Apache Cassandra Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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.
  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
