Why teams connect Google Cloud Spanner and Salesforce

Treat Salesforce like part of your database: its records live in Google Cloud Spanner 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 Google Cloud Spanner, where it can be queried and joined like everything else.

Stacksync mirrors Custom Objects, Accounts, Contacts, Leads from Salesforce into Databases, Tables, Rows, Interleaved tables in Google Cloud Spanner 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

  • Consolidate multiple Salesforce orgs into a single database for cross-org reporting after an acquisition.
  • Sync Accounts, Contacts, and Opportunities bi-directionally with Postgres so engineering teams read and write CRM data with plain SQL.
  • Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.

Trigger workflows from CRM changes

Field and stage updates in Salesforce arrive as row changes in Google Cloud Spanner, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Salesforce become tables in Google Cloud Spanner you can join with application data directly.

Product events onto CRM records

Signup, usage, or lifecycle changes written to Google Cloud Spanner sync onto the matching records in Salesforce, giving go-to-market teams live product context.

Google Cloud Spanner objects Salesforce objects
Tables Relational tables mapped one-to-one to sync targets. Accounts Company records that anchor most syncs; typically mapped to customer tables in a database or ERP.
Rows The unit of read and write in each sync cycle, keyed by primary key. Contacts People linked to Accounts; synced two-way with marketing, support, and warehouse person records.
Interleaved tables Child rows physically co-located with parents; synced as related records. Leads Unqualified prospects; often written into Salesforce from enrichment or product-signup pipelines.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Opportunities Deal records with stage and amount; synced to databases for pipeline reporting and to ERPs at close.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Cases Support records; synced with help desk tools or internal databases for escalation workflows.
Views Read-only projections useful for shaping data before it leaves Spanner. Campaigns Marketing membership data; read out for attribution analysis in the warehouse.
