Why teams connect Azure Synapse Analytics and Eloqua

Put modeled data to work and measure what it drives: Azure Synapse Analytics and Eloqua keep contacts, audiences, and campaign results in step in real time, in both directions.

Azure Synapse Analytics is where your team models customers, product usage, and revenue into trusted tables; Eloqua runs the campaigns, audiences, and messages that reach those people. The two overlap wherever the same person, account, or segment matters to both, and when the bridge between them is a nightly export or a hand-built list, marketing targets stale data while analytics never sees what the campaign returned.

Stacksync syncs Schemas, Materialized views, SQL pools, Tables (dedicated SQL pool) in Azure Synapse Analytics with Campaigns, Emails, Forms and Form Submits, Contact Lists and Segments in Eloqua field by field, in real time, and in both directions. You decide which system owns which fields — a computed score or segment can flow out to Eloqua while sends, opens, and conversions flow back to Azure Synapse Analytics — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

Common use cases

  • 01 Sync curated Synapse views into an operational Postgres or Azure SQL database that applications can query cheaply.
  • 02 Consolidate SaaS data alongside lake data so analysts join both through one SQL surface.
  • 03 Export email opens, clicks, form submits, and bounces from the Bulk API Activities export into a warehouse for lead scoring and multi-touch attribution.
  • 04 Load purchase or product-usage records into Custom Data Objects linked to Contacts so nurture campaigns branch on behavior mastered in another system.

Common sync patterns

Suppression and consent stay aligned

Unsubscribes, bounces, and consent or opt-out flags held in either system propagate to the other, so no one is messaged after opting out and Azure Synapse Analytics holds the current state for auditing.

Enrich records with warehouse context

Product-usage counts, plan tier, region, or account owner computed in Azure Synapse Analytics appear on the matching record in Eloqua, so targeting, routing, and personalization use up-to-date context.

Activate a modeled audience

A segment or score built in Azure Synapse Analytics — high-intent accounts, churn risk, a lifetime-value tier — lands as an audience or contact field in Eloqua, so campaigns target the people your data actually points to instead of a static export.

What you can sync between Azure Synapse Analytics and Eloqua

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.

Azure Synapse Analytics objects Eloqua objects How this pairing syncs
SQL pools Dedicated or serverless compute contexts that determine how and where queries run. Forms and Form Submits Form definitions and their submission data, accessed through the Application REST API; submissions read out into a warehouse for lead capture and analysis. SQL pools is specific to Azure Synapse Analytics and Forms and Form Submits to Eloqua — each maps to any object or custom field on the other side.
Tables (dedicated SQL pool) Distributed warehouse tables that serve as sync destinations for analytics workloads. Contact Lists and Segments Shared lists (static) and segments (dynamic audiences); Contacts are added to or removed from shared lists based on lifecycle stage computed downstream. Tables (dedicated SQL pool) is specific to Azure Synapse Analytics and Contact Lists and Segments to Eloqua — each maps to any object or custom field on the other side.
External tables Tables over files in the data lake, queried through serverless SQL and often read-only in syncs. Contacts Core person records, keyed on email address as the unique identifier; imported/exported via the Bulk API and upserted on email, synced two-way with CRM, warehouse, and app databases. External tables is specific to Azure Synapse Analytics and Contacts to Eloqua — each maps to any object or custom field on the other side.
Views Curated projections used when downstream tools should not read base tables directly. Accounts Company records linked to Contacts via the account-linkage field; moved through the Bulk API and typically mastered in a CRM or ERP and written into Eloqua. Views is specific to Azure Synapse Analytics and Accounts to Eloqua — each maps to any object or custom field on the other side.
Schemas Namespaces that separate staging, integration, and presentation layers. Custom Data Objects Auxiliary data tables (CDOs) linked to Contacts for records like event registrations or purchases; synced via the Bulk API so nurture campaigns can branch on them. Schemas is specific to Azure Synapse Analytics and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side.
Materialized views Precomputed aggregates that speed reads of frequently synced result sets. Activities Engagement events (email opens, clicks, form submits, bounces, page views, subscribes/unsubscribes) exported through the Bulk API activities export; read-only feed for scoring and attribution. Materialized views is specific to Azure Synapse Analytics and Activities to Eloqua — each maps to any object or custom field on the other side.

How changes propagate between Azure Synapse Analytics and Eloqua

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.

Azure Synapse Analytics Eloqua Interval-based propagation

DetectionStacksync polls Azure Synapse Analytics for changes on an incremental schedule, reading only records changed since the previous pass. Polling on watermark columns.

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

Eloqua Azure Synapse Analytics Interval-based propagation

DetectionStacksync polls Eloqua for changes on an incremental schedule, reading only records changed since the previous pass. Polling via Bulk API exports filtered on a contact/account modified-date field using EML filter syntax.

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

Rate-limit considerations

  • Eloqua: Per-instance soft limits by sync type (Export 2,000/hr, Import 2,000/hr, Sync Action 4,000/hr); 32 MB cap per POST to a staging area and 50,000 records per retrieve batch.
