Why teams connect AWS Aurora PostgreSQL and IBM Db2

Keep AWS Aurora PostgreSQL and IBM Db2 synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between AWS Aurora PostgreSQL and IBM Db2 continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • 01 Feed operational dashboards from a read replica while the writer handles sync traffic.
  • 02 Expose ERP records such as customers, orders, and invoices as Postgres tables the engineering team can query and update with plain SQL.
  • 03 Feed changes captured from Db2 logs into downstream event pipelines.
  • 04 Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.

Common sync patterns

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What you can sync between AWS Aurora PostgreSQL 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.

AWS Aurora PostgreSQL objects IBM Db2 objects How this pairing syncs
Tables The core sync unit; rows are matched across systems by primary key. 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.
Databases and schemas PostgreSQL's two-level namespace scopes which tables a sync connection targets. Databases The connection target; each database holds the schemas a sync addresses. Databases and schemas is specific to AWS Aurora PostgreSQL and Databases to IBM Db2 — each maps to any object or custom field on the other side.
Rows Inserted, updated, and deleted in both directions during bi-directional syncs. Schemas Namespaces separating synced data from application and system objects. Rows is specific to AWS Aurora PostgreSQL and Schemas to IBM Db2 — each maps to any object or custom field on the other side.
Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Views Read-only projections often used to expose curated slices to a sync. Columns is specific to AWS Aurora PostgreSQL and Views to IBM Db2 — each maps to any object or custom field on the other side.
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Indexes Support fast key lookups on sync match columns. Primary keys and constraints is specific to AWS Aurora PostgreSQL and Indexes to IBM Db2 — each maps to any object or custom field on the other side.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Stored Procedures Existing business logic sometimes invoked as part of write paths. Views and materialized views is specific to AWS Aurora PostgreSQL and Stored Procedures to IBM Db2 — each maps to any object or custom field on the other side.

How changes propagate between AWS Aurora PostgreSQL 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.

AWS Aurora PostgreSQL IBM Db2 Sub-second propagation

DetectionChanges in AWS Aurora PostgreSQL are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication (WAL decoding through replication slots), with timestamp polling as a fallback.

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

IBM Db2 AWS Aurora PostgreSQL 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.

Rate-limit considerations

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