Why teams connect Couchbase and Eloqua

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

Eloqua 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 Couchbase, hard to get into campaigns without manual exports.

Stacksync mirrors Contacts, Accounts, Custom Data Objects, Activities from Eloqua into Global Secondary Indexes, XDCR replications, Full-text search indexes, Buckets in Couchbase 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 Couchbase, from usage, orders, or account status, sync back into Eloqua to drive campaigns and ads, with Eloqua kept authoritative for engagement. You decide which side owns which fields, and Stacksync resolves conflicts by rules you set.

Common use cases

  • 01 Consolidate documents from multiple Couchbase clusters into a single analytical store.
  • 02 Write cleaned or enriched records from operational databases back into Couchbase collections that applications read.
  • 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

Query Eloqua like a database

Contacts, leads, audiences, and campaign metrics from Eloqua live in Couchbase 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 Couchbase from product usage, orders, or account status sync into Eloqua 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 Eloqua land in Couchbase beside the matching customer record, ready for reporting and revenue attribution.

What you can sync between Couchbase 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.

Couchbase objects Eloqua objects How this pairing syncs
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. 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. JSON Documents is specific to Couchbase and Custom Data Objects to Eloqua — each maps to any object or custom field on the other side.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. 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. Global Secondary Indexes is specific to Couchbase and Activities to Eloqua — each maps to any object or custom field on the other side.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Campaigns Multi-step campaign-canvas assets managed through the Application REST API; campaign membership and response data read out for attribution reporting. XDCR replications is specific to Couchbase and Campaigns to Eloqua — each maps to any object or custom field on the other side.
Full-text search indexes Search indexes over documents, relevant when syncing searchable content. Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Full-text search indexes is specific to Couchbase and Emails to Eloqua — each maps to any object or custom field on the other side.
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. 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. Buckets is specific to Couchbase and Forms and Form Submits to Eloqua — each maps to any object or custom field on the other side.
Scopes Namespaces inside a bucket used to group collections, similar to schemas. 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. Scopes is specific to Couchbase and Contact Lists and Segments to Eloqua — each maps to any object or custom field on the other side.

How changes propagate between Couchbase 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.

Couchbase Eloqua Sub-second propagation

DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.

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

Eloqua Couchbase 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 Couchbase as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Couchbase: Throughput is bounded by cluster sizing rather than API rate limits.
  • 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.
