Why teams connect Google Cloud Spanner and StarRocks

Connect Google Cloud Spanner and StarRocks 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 StarRocks, 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 StarRocks in real time, and result tables in StarRocks sync back into Google Cloud Spanner, with schema and type mapping between the two systems handled for you.

Common use cases

  • Continuously apply upserts from operational databases into Primary Key tables to keep analytics current
  • Serve customer-facing analytics from SaaS data synced into one analytical store
  • Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.

Serve warehouse results at database speed

Aggregates or model outputs computed in StarRocks 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.

Offload heavy reads

Point analytical queries at the synced copy in StarRocks and keep Google Cloud Spanner focused on its operational workload.

What you can sync between Google Cloud Spanner and StarRocks

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 StarRocks objects
Change streams Capture inserts, updates, and deletes for log-style change data capture. Materialized views Automatically maintained rollups used to accelerate queries on synced data.
Views Read-only projections useful for shaping data before it leaves Spanner. Views Logical views for shaping analytical reads.
Databases Top-level containers that scope schema and sync configuration. Partitions Time or range partitions that scope loads and retention.
Tables Relational tables mapped one-to-one to sync targets. Columns Columnar storage with types mapped from source systems during sync.
Rows The unit of read and write in each sync cycle, keyed by primary key. Databases Top-level namespaces addressed exactly as in MySQL clients.
Interleaved tables Child rows physically co-located with parents; synced as related records. Tables Defined with a table model (Primary Key, Unique Key, Aggregate, Duplicate Key) that determines update behavior.

How the Google Cloud Spanner and StarRocks connectors work

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.

StarRocks

Integration surface
MySQL wire protocol for SQL; HTTP-based Stream Load API for ingestion
Authentication
Database credentials (MySQL-compatible username/password)
Change detection
Query-based polling when reading; StarRocks is most often the destination side of a sync
Capabilities
read · write
Rate limits
Ingestion throughput is bounded by cluster resources rather than API quotas
