Why teams connect Databricks and Google Cloud Spanner

Connect Google Cloud Spanner and Databricks with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want Google Cloud Spanner's rows in Databricks, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in Google Cloud Spanner where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in Google Cloud Spanner sync into Databricks in real time, and result tables in Databricks sync back into Google Cloud Spanner, with schema and type mapping between the two systems handled for you.

Common use cases

  • Land CRM and ERP records in Delta tables continuously so lakehouse models work from current operational data.
  • Use Change Data Feed to propagate only changed rows to downstream apps instead of full-table scans.
  • 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.

Operational data in the warehouse, minus the pipeline

Rows from Google Cloud Spanner land in Databricks as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Databricks sync into Google Cloud Spanner, where whatever reads from that database gets them without querying the warehouse.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

What you can sync between Databricks 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.

Databricks objects Google Cloud Spanner objects
SQL Warehouses The compute endpoint a sync connects to for query execution. Interleaved tables Child rows physically co-located with parents; synced as related records.
Change Data Feed Row-level change records on Delta tables that drive incremental reads. Secondary indexes Used to make incremental read queries efficient on non-key columns.
Catalogs Top level of the Unity Catalog namespace, scoping which schemas a sync can address. Change streams Capture inserts, updates, and deletes for log-style change data capture.
Schemas Group tables and views; syncs typically target a dedicated schema per source system. Views Read-only projections useful for shaping data before it leaves Spanner.
Delta Tables The primary read and write target; operational data lands here as managed or external tables. Databases Top-level containers that scope schema and sync configuration.
Views Curated read-only projections used as sync sources for downstream tools. Tables Relational tables mapped one-to-one to sync targets.

How the Databricks and Google Cloud Spanner connectors work

Databricks

Integration surface
SQL over JDBC/ODBC via SQL warehouses, plus a REST API including statement execution
Authentication
Personal access tokens or OAuth machine-to-machine credentials for service principals
Change detection
Delta Lake Change Data Feed for row-level changes; otherwise incremental polling on watermark columns
Capabilities
read · write · CDC
Rate limits
Throughput depends on the SQL warehouse size; API calls are subject to workspace rate limits

Google Cloud Spanner

Integration surface
gRPC/REST client API with SQL query surface (GoogleSQL and PostgreSQL-interface dialects)
Authentication
Google Cloud IAM (service accounts)
Change detection
Change streams (log-style CDC), or timestamp-based polling queries
Capabilities
read · write · CDC
Rate limits
Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
