Why teams connect Greenplum and IBM Db2

Connect IBM Db2 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 IBM Db2'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 IBM Db2 where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in IBM Db2 sync into Greenplum in real time, and result tables in Greenplum sync back into IBM Db2, with schema and type mapping between the two systems handled for you.

Common use cases

  • 01 Keep Greenplum and a cloud warehouse in sync during a migration so both platforms serve consistent data.
  • 02 Feed BI reporting by syncing curated Greenplum views to downstream tools on a schedule.
  • 03 Keep reference and master data aligned between Db2 and newer cloud databases during modernization projects.
  • 04 Feed changes captured from Db2 logs into downstream event pipelines.

Common sync patterns

Offload heavy reads

Point analytical queries at the synced copy in Greenplum and keep IBM Db2 focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from IBM Db2 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 IBM Db2, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Greenplum and IBM Db2

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 IBM Db2 objects How this pairing syncs
Databases Top-level containers that scope a sync connection. Databases The connection target; each database holds the schemas a sync addresses. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespace tables and control which objects a sync can see. Schemas Namespaces separating synced data from application and system objects. 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 Primary read/write target for syncing rows with SaaS systems or other databases. 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 Read-only projections often used to expose curated slices to a sync. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Rows Read and written by key; distribution keys determine where rows live. Stored Procedures Existing business logic sometimes invoked as part of write paths. Rows is specific to Greenplum and Stored Procedures to IBM Db2 — each maps to any object or custom field on the other side.
Partitions Large tables are commonly partitioned by date, which shapes incremental reads. Sequences ID generation relevant when external systems insert rows. Partitions is specific to Greenplum and Sequences to IBM Db2 — each maps to any object or custom field on the other side.

How changes propagate between Greenplum and IBM Db2

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 IBM Db2 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 IBM Db2 as a row-level write, with types converted between the two schemas.

IBM Db2 Greenplum Sub-second propagation

DetectionChanges in IBM Db2 are captured at the source via change data capture — no polling loop against its API. Log-based CDC through IBM's replication tooling where licensed.

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.
  • IBM Db2: No API rate limits; throughput is bounded by instance resources and workload management settings.
