Why teams connect Google AlloyDB and Greenplum

Connect Google AlloyDB and Greenplum 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 AlloyDB's rows in Greenplum, 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 AlloyDB 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 AlloyDB sync into Greenplum in real time, and result tables in Greenplum sync back into Google AlloyDB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Publish segments, scores, and aggregates computed in Greenplum back into business tools where teams act on them.
  • Keep Greenplum and a cloud warehouse in sync during a migration so both platforms serve consistent data.
  • Mirror CRM objects into AlloyDB tables so product and internal tools query customer data with plain SQL.
  • Use logical replication to feed AlloyDB changes into warehouses or event pipelines without batch jobs.

Offload heavy reads

Point analytical queries at the synced copy in Greenplum and keep Google AlloyDB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from Google AlloyDB land in Greenplum as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

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

What you can sync between Google AlloyDB and Greenplum

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 AlloyDB objects Greenplum objects
Indexes Keep sync key lookups fast on high-volume tables. Databases Top-level containers that scope a sync connection.
Sequences ID generation relevant when external systems insert rows. Schemas Namespace tables and control which objects a sync can see.
Replication Slots Logical replication artifacts that back log-based change capture. Tables Heap or append-optimized tables mapped directly to sync targets.
Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Partitions Large tables are commonly partitioned by date, which shapes incremental reads.
Schemas Namespaces used to separate synced SaaS data from application tables. Views Read-only projections used to shape data before syncing it out.
Tables Primary read/write target for bi-directional sync with CRMs and other systems. External tables Reference external files for bulk load paths alongside row-level syncs.

How the Google AlloyDB and Greenplum connectors work

Google AlloyDB

Integration surface
SQL wire protocol (PostgreSQL-compatible), with connectivity through the AlloyDB Auth Proxy or private IP
Authentication
Database credentials or IAM database authentication
Change detection
Log-based CDC via PostgreSQL logical replication; polling on timestamp columns as a fallback
Capabilities
read · write · CDC
Rate limits
No API-style rate limits; throughput is bounded by instance size

Greenplum

Integration surface
PostgreSQL wire protocol (libpq), plus JDBC/ODBC drivers
Authentication
Database credentials
Change detection
Polling with timestamp or key-based cursors; Greenplum does not expose logical-decoding CDC
Capabilities
read · write
Rate limits
Bounded by cluster resources and concurrency settings rather than an API quota.
How it works

How to connect Google AlloyDB to Greenplum — three steps, no code
