Why teams connect Exasol and IBM Db2

Connect IBM Db2 and Exasol 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 Exasol, 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 Exasol in real time, and result tables in Exasol sync back into IBM Db2, with schema and type mapping between the two systems handled for you.

Common use cases

  • 01 Sync computed metrics or customer segments from Exasol back into a CRM for sales and marketing use (reverse ETL).
  • 02 Consolidate data from multiple operational databases into Exasol as the central analytics layer.
  • 03 Replicate Db2 tables into a cloud warehouse continuously instead of nightly batch extracts.
  • 04 Keep reference and master data aligned between Db2 and newer cloud databases during modernization projects.

Common sync patterns

Offload heavy reads

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

Operational data in the warehouse, minus the pipeline

Rows from IBM Db2 land in Exasol as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Exasol sync into IBM Db2, where whatever reads from that database gets them without querying the warehouse.

What you can sync between Exasol 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.

Exasol objects IBM Db2 objects How this pairing syncs
Schemas Namespaces that group the tables a sync reads from or writes into. 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 Primary sync target; columnar relational tables written with standard SQL. 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 query surfaces often used as curated sources for reverse ETL. 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.
Users and roles Grant read/write access for the dedicated integration account. Sequences ID generation relevant when external systems insert rows. Users and roles is specific to Exasol and Sequences to IBM Db2 — each maps to any object or custom field on the other side.
Virtual schemas Federated views over external sources; useful for deciding what needs physical replication. Tablespaces Physical storage layout that operators consider when adding synced tables. Virtual schemas is specific to Exasol and Tablespaces to IBM Db2 — each maps to any object or custom field on the other side.
UDF scripts In-database functions that can transform synced data after load. Databases The connection target; each database holds the schemas a sync addresses. UDF scripts is specific to Exasol and Databases to IBM Db2 — each maps to any object or custom field on the other side.

How changes propagate between Exasol 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.

Exasol IBM Db2 Interval-based propagation

DetectionStacksync polls Exasol for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key columns.

DeliveryEach detected change is applied to IBM Db2 as a row-level write, with types converted between the two schemas.

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

Rate-limit considerations

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