Why teams connect Greenplum and Oracle DB

Connect Oracle DB 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 Oracle DB'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 Oracle DB where the services that read from it get them at normal query latency.

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

Common use cases

  • 01 Feed BI reporting by syncing curated Greenplum views to downstream tools on a schedule.
  • 02 Consolidate data from multiple source systems into partitioned Greenplum fact tables.
  • 03 Keep legacy Oracle applications running while newer services read and write the same data through a synced copy.
  • 04 Write changes from SaaS apps back into Oracle so PL/SQL jobs and reports run on current data.

Common sync patterns

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 Greenplum and keep Oracle DB focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between Greenplum and Oracle DB

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.

Greenplum objects Oracle DB objects How this pairing syncs
Schemas Namespace tables and control which objects a sync can see. Schemas Per-user namespaces that scope sync permissions and object visibility Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Heap or append-optimized tables mapped directly to sync targets. Tables The primary read/write surface for row-level sync over SQL Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Partitions Physical subdivisions relevant when replicating high-volume tables Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections used to shape data before syncing it out. Views Curated read-only projections exposed to downstream consumers Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
External tables Reference external files for bulk load paths alongside row-level syncs. Materialized views Precomputed results occasionally used as stable replication sources External tables is specific to Greenplum and Materialized views to Oracle DB — each maps to any object or custom field on the other side.
Rows Read and written by key; distribution keys determine where rows live. Sequences Key generators to respect when external systems insert rows Rows is specific to Greenplum and Sequences to Oracle DB — each maps to any object or custom field on the other side.

How changes propagate between Greenplum and Oracle DB

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.

Greenplum Oracle DB 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 Oracle DB as a row-level write, with types converted between the two schemas.

Oracle DB Greenplum Sub-second propagation

DetectionChanges in Oracle DB are captured at the source via change data capture — no polling loop against its API. Log-based CDC from redo logs via LogMiner or GoldenGate, or trigger and timestamp polling.

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

Rate-limit considerations

  • Greenplum: Bounded by cluster resources and concurrency settings rather than an API quota.
  • Oracle DB: Throughput bounded by database resources rather than API quotas.
