Why teams connect Apache Cassandra and Salesforce

Treat Salesforce 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 Leads, Opportunities, Cases, Campaigns from Salesforce 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 Salesforce 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

  • Sync Accounts, Contacts, and Opportunities bi-directionally with Postgres so engineering teams read and write CRM data with plain SQL.
  • Write product usage metrics computed in a warehouse onto Account and Contact fields so reps see adoption signals on the record.
  • Write attributes computed elsewhere (scores, preferences) back into Cassandra tables serving low-latency reads.
  • Feed Cassandra change streams into search indexes or caches that must track the source of truth.

Trigger workflows from CRM changes

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

What you can sync between Apache Cassandra and Salesforce

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 Salesforce objects
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines.
Collections List, set, and map columns handled with type-aware field mapping. Opportunities Deal records with stage and amount; synced to databases for pipeline reporting and to ERPs at close.
Counters Increment-only counter columns, usually read-only in syncs. Cases Support records; synced with help desk tools or internal databases for escalation workflows.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Campaigns Marketing membership data; read out for attribution analysis in the warehouse.

At scale

Event queues

Handle millions of events per minute without losing a single Apache Cassandra or Salesforce record.

Observability

Monitoring

Track your Apache Cassandra ⇄ Salesforce sync health, view errors, and replay failed events in one click.

Trading partners

EDI

How the Apache Cassandra and Salesforce 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
read · write · CDC
Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

Salesforce

Integration surface
REST, SOAP, and Bulk APIs
Authentication
OAuth login via a Salesforce user (browser-based authorization flow); requires "API Enabled" permission for polling mode, plus "Author Apex" and "Customize Application" OR "Modify All Data" for trigger mode
Change detection
Apex triggers are used whenever possible (Salesforce actively notifies Stacksync via an Apex trigger + callout class + remote site setting)
Capabilities
read · write · CDC
Rate limits
Daily API request allocations vary by edition and license count.

How it works

How to connect Apache Cassandra to Salesforce — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate Apache Cassandra and Salesforce with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
