Why teams connect Eloqua and Google Cloud Spanner

Give your team Eloqua's contacts, campaigns, and engagement in Google Cloud Spanner: 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 Google Cloud Spanner, hard to get into campaigns without manual exports.

Stacksync mirrors Contact Lists and Segments, Contacts, Accounts, Custom Data Objects from Eloqua into Secondary indexes, Change streams, Views, Databases in Google Cloud Spanner 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 Google Cloud Spanner, 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 Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • 02 Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • 03 Add or remove Contacts from shared Contact Lists and Segments based on lifecycle stage computed downstream in a database.
  • 04 Two-way sync Contacts between Eloqua and a Postgres or warehouse table, matched on email, so ops teams query and update marketing profiles in SQL while marketers keep working in Eloqua.

Common sync patterns

React to marketing changes as row changes

A new lead, form fill, or list change in Eloqua arrives as a row change in Google Cloud Spanner, so scoring, jobs, and notifications run in the tooling your team already uses.

Keep contact attributes consistent

Lifecycle stage, subscription status, or plan maintained on either side stays current on the other, ending exports and dual data entry.

Query Eloqua like a database

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

What you can sync between Eloqua and Google Cloud Spanner

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.

Eloqua objects Google Cloud Spanner objects How this pairing syncs
Emails Email creative and email-group assets managed via the Application REST API; usually read for reporting rather than written by a sync. Change streams Capture inserts, updates, and deletes for log-style change data capture. Emails is specific to Eloqua and Change streams to Google Cloud Spanner — each maps to any object or custom field on the other side.
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. Views Read-only projections useful for shaping data before it leaves Spanner. Forms and Form Submits is specific to Eloqua and Views to Google Cloud Spanner — each maps to any object or custom field on the other side.
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. Databases Top-level containers that scope schema and sync configuration. Contact Lists and Segments is specific to Eloqua and Databases to Google Cloud Spanner — each maps to any object or custom field on the other side.
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. Tables Relational tables mapped one-to-one to sync targets. Contacts is specific to Eloqua and Tables to Google Cloud Spanner — each maps to any object or custom field on the other side.
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. Rows The unit of read and write in each sync cycle, keyed by primary key. Accounts is specific to Eloqua and Rows to Google Cloud Spanner — each maps to any object or custom field on the other side.
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. Interleaved tables Child rows physically co-located with parents; synced as related records. Custom Data Objects is specific to Eloqua and Interleaved tables to Google Cloud Spanner — each maps to any object or custom field on the other side.

How changes propagate between Eloqua and Google Cloud Spanner

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.

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

Google Cloud Spanner Eloqua Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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

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.
  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
