Why teams connect Google Cloud Spanner and Seismic

Treat Seismic 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 Teamsites, LiveSend Links, Digital Sales Rooms, Reporting Activities from Seismic 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 Seismic 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

  • 01 Sync Library Content metadata and Custom Property Schemas with a DAM or PIM so one taxonomy governs assets across systems.
  • 02 React to ContentManager and DSR webhook events to update a database when documents are published, versioned, or expired.
  • 03 Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • 04 Consolidate data from a globally distributed Spanner deployment into regional business systems.

Common sync patterns

Query the CRM like a database

Accounts, contacts, and custom objects from Seismic 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 Seismic, giving go-to-market teams live product context.

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Seismic API, limits, and retries.

What you can sync between Google Cloud Spanner and Seismic

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.

Google Cloud Spanner objects Seismic objects How this pairing syncs
Databases Top-level containers that scope schema and sync configuration. Library Content Documents, decks, and assets stored in teamsites; created, moved, and retrieved via the Content Management API, each with a contentId. Databases is specific to Google Cloud Spanner and Library Content to Seismic — each maps to any object or custom field on the other side.
Tables Relational tables mapped one-to-one to sync targets. Content Versions Version history for a library item; new versions upload via API and old ones expire, with events firing on ContentManager webhooks. Tables is specific to Google Cloud Spanner and Content Versions to Seismic — each maps to any object or custom field on the other side.
Rows The unit of read and write in each sync cycle, keyed by primary key. Users User records managed through SCIM 2.0 and legacy user endpoints; created, updated, and deactivated for provisioning sync. Rows is specific to Google Cloud Spanner and Users to Seismic — each maps to any object or custom field on the other side.
Interleaved tables Child rows physically co-located with parents; synced as related records. User Groups Group definitions and membership that govern content access; synced from an IdP or HRIS to keep permissions current. Interleaved tables is specific to Google Cloud Spanner and User Groups to Seismic — each maps to any object or custom field on the other side.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Teamsites Tenant-scoped workspace partitions organizing Library content, permissions, and config; scoped by teamSiteId on most content calls. Secondary indexes is specific to Google Cloud Spanner and Teamsites to Seismic — each maps to any object or custom field on the other side.
Change streams Capture inserts, updates, and deletes for log-style change data capture. LiveSend Links Trackable content-share links created via the engagement API; their open and view engagement is read back through Reporting. Change streams is specific to Google Cloud Spanner and LiveSend Links to Seismic — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Spanner and Seismic

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.

Google Cloud Spanner Seismic 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 Seismic through its API, with automatic retries and rate-limit backoff.

Seismic Google Cloud Spanner Sub-second propagation

DetectionSeismic notifies Stacksync of record changes through webhook events. Webhooks for content, version, user, group, workflow, DSR, and LiveSend events.

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

Rate-limit considerations

  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
  • Seismic: Tiered per-endpoint limits over a rolling 60-second window; exceeding returns HTTP 429, with X-Seismic-Remaining-Calls and X-Seismic-Total-Calls headers.
