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

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

Common sync patterns

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 How this pairing syncs
Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Databases Top-level containers that scope a sync connection. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespaces used to separate synced SaaS data from application tables. Schemas Namespace tables and control which objects a sync can see. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Primary read/write target for bi-directional sync with CRMs and other systems. Tables Heap or append-optimized tables mapped directly to sync targets. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Curated projections used as read-only sync sources. Views Read-only projections used to shape data before syncing it out. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Indexes Keep sync key lookups fast on high-volume tables. Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Indexes is specific to Google AlloyDB and Partitions to Greenplum — each maps to any object or custom field on the other side.
Sequences ID generation relevant when external systems insert rows. External tables Reference external files for bulk load paths alongside row-level syncs. Sequences is specific to Google AlloyDB and External tables to Greenplum — each maps to any object or custom field on the other side.

How changes propagate between Google AlloyDB and Greenplum

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 AlloyDB Greenplum Sub-second propagation

DetectionChanges in Google AlloyDB are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication.

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

Greenplum Google AlloyDB Interval-based propagation

DetectionStacksync polls Greenplum for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key-based cursors.

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

Rate-limit considerations

  • Google AlloyDB: No API-style rate limits; throughput is bounded by instance size.
  • Greenplum: Bounded by cluster resources and concurrency settings rather than an API quota.
