Why teams connect Salesforce Marketing Cloud and VoltDB

Give your team Salesforce Marketing Cloud's contacts, campaigns, and engagement in VoltDB: query them with SQL, push audiences built from your own data back to Salesforce Marketing Cloud, and skip the marketing API.

Salesforce Marketing Cloud holds the people, audiences, and campaign activity that marketing runs on, but that data sits behind interfaces built for marketers, not for your internal systems. Engineers and analysts who need contacts, list membership, or engagement, for reporting, attribution, or product logic, end up writing integration code against a rate-limited API and maintaining it forever. Meanwhile the customer and usage data marketers want for targeting already lives in VoltDB, hard to get into campaigns without manual exports.

Stacksync mirrors Transactional Sends, Data Extensions, Contacts / Subscribers, Journeys (Journey Builder) from Salesforce Marketing Cloud into Replicated Tables, Stored Procedures, Materialized Views, Streams in VoltDB field by field, in real time, and in both directions. Marketing records become rows your code can query and join with product and customer data; audiences and attributes computed in VoltDB, from usage, orders, or account status, sync back into Salesforce Marketing Cloud to drive campaigns and ads, with Salesforce Marketing Cloud kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Push aggregates from VoltDB materialized views into dashboards or operational tools.
  • 02 Sync customer or account reference data from a CRM into VoltDB replicated tables for in-transaction lookups such as fraud or policy checks.
  • 03 Push CRM or warehouse audience segments into Data Extensions via the async rows API (background bulk insert) so marketing sends to freshly built audiences without manual CSV imports.
  • 04 Fire Journey Builder entry events (/interaction/v1/events) from an app or database when a contact acts, so behavioral journeys trigger on live events instead of scheduled batch loads.

Common sync patterns

Query Salesforce Marketing Cloud like a database

Contacts, leads, audiences, and campaign metrics from Salesforce Marketing Cloud live in VoltDB as ordinary tables or collections, joinable with the rest of your data and reachable without touching the vendor API.

Build audiences from your own data

Segments computed in VoltDB from product usage, orders, or account status sync into Salesforce Marketing Cloud as lists or audiences, so campaigns and ads target the people your data says they should.

Engagement and results next to the customer

Opens, clicks, sends, RSVPs, or ad activity from Salesforce Marketing Cloud land in VoltDB beside the matching customer record, ready for reporting and revenue attribution.

What you can sync between Salesforce Marketing Cloud and VoltDB

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.

Salesforce Marketing Cloud objects VoltDB objects How this pairing syncs
Contacts / Subscribers The contact model keyed by Subscriber Key, holding channel addresses and subscription status; managed through the Contacts API (/contacts/v1/contacts) and the SOAP Subscriber object, and referenced by every send and journey. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Contacts / Subscribers is specific to Salesforce Marketing Cloud and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side.
Journeys (Journey Builder) Multi-step automated flows read and managed via /interaction/v1/interactions; contacts are injected by firing an entry event to /interaction/v1/events with an EventDefinitionKey and contact data. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Journeys (Journey Builder) is specific to Salesforce Marketing Cloud and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side.
Content Assets (Content Builder) Emails, templates, images, and reusable content blocks stored in Content Builder and read or written via /asset/v1/content/assets, used to compose the messages a journey or send delivers. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. Content Assets (Content Builder) is specific to Salesforce Marketing Cloud and Replicated Tables to VoltDB — each maps to any object or custom field on the other side.
Automations (Automation Studio) Scheduled or triggered workflows of import, query, extract, and send activities managed via /automation/v1/automations; SQL Query Activities read Data Views and write results into Data Extensions. Stored Procedures Precompiled transactional units that serve as the primary write interface. Automations (Automation Studio) is specific to Salesforce Marketing Cloud and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.
Tracking Events Sent, Open, Click, Bounce, Unsubscribe, and NotSent events retrieved through the SOAP tracking objects (SentEvent, OpenEvent, ClickEvent, BounceEvent) or the Automation Studio Data Views (_Sent, _Open, _Click, _Bounce) - the queryable record of engagement per send. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. Tracking Events is specific to Salesforce Marketing Cloud and Materialized Views to VoltDB — each maps to any object or custom field on the other side.
Transactional Sends Triggered and transactional Email/SMS delivered through the Messaging API (/messaging/v1/email/messages/{key}); the Event Notification Service reports each message's disposition (delivered, bounced, opened, clicked). Streams Insert-only constructs that feed the export subsystem with committed rows. Transactional Sends is specific to Salesforce Marketing Cloud and Streams to VoltDB — each maps to any object or custom field on the other side.

How changes propagate between Salesforce Marketing Cloud and VoltDB

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.

Salesforce Marketing Cloud VoltDB Sub-second propagation

DetectionSalesforce Marketing Cloud notifies Stacksync of record changes through webhook events. The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback.

DeliveryEach detected change is applied to VoltDB as a row-level write, with types converted between the two schemas.

VoltDB Salesforce Marketing Cloud Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

DeliveryEach detected change is written to Salesforce Marketing Cloud through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Salesforce Marketing Cloud: Salesforce does not publish fixed numeric REST rate limits; requests are throttled per account and can return HTTP 429, so backoff is advised. SOAP Retrieve returns at most 2,500 records per call and pages via ContinueRequest with the prior RequestID. Bulk Data Extension writes use the async rows API to queue inserts in the background.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.

How the Salesforce Marketing Cloud and VoltDB connectors work

Salesforce Marketing Cloud

Integration surface
Two APIs on tenant-specific endpoints: a REST API (JSON over HTTPS) for Data Extensions, Journeys, Contacts, Content Builder, and Automations, plus a legacy SOAP API (ExactTarget WSDL) for tracking events and bulk Retrieve.
Authentication
OAuth 2.0 via an Installed Package (Client ID + Client Secret). Server-to-server uses the client_credentials grant and web apps use authorization_code, both against {subdomain}.auth.marketingcloudapis.com/v2/token. The 20-minute access token response also returns the account's rest_instance_url and soap_instance_url.
Change detection
The Event Notification Service (ENS) issues HTTPS POST callbacks for transactional Email and SMS events (sent, bounce, open, click) once a callback URL and subscription are registered and verified. There is no general data-change feed, so Data Extension and Data View syncs poll by date fields.
