Why teams connect Google Cloud SQL and IBM Db2

Keep Google Cloud SQL 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 Google Cloud SQL 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 Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.
  • 02 Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.
  • 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

Cross-engine sync

Keep the same dataset live in both Google Cloud SQL and IBM Db2, so each workload runs on the engine that suits it.

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.

What you can sync between Google Cloud SQL 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.

Google Cloud SQL objects IBM Db2 objects How this pairing syncs
Databases Scope the tables included in a sync configuration. 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 in PostgreSQL and SQL Server instances. 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 Mapped directly to sync targets; schema changes can be propagated. 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 sources for shaping 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.
Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to. Tablespaces Physical storage layout that operators consider when adding synced tables. Instances is specific to Google Cloud SQL and Tablespaces to IBM Db2 — each maps to any object or custom field on the other side.
Rows Read and written by primary key during each sync cycle. Indexes Support fast key lookups on sync match columns. Rows is specific to Google Cloud SQL and Indexes to IBM Db2 — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud SQL 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.

Google Cloud SQL IBM Db2 Sub-second propagation

DetectionChanges in Google Cloud SQL are captured at the source via change data capture — no polling loop against its API. Engine-dependent log-based CDC: MySQL binlog, PostgreSQL logical replication, SQL Server change tracking.

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

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

  • Google Cloud SQL: Constrained by instance size and connection limits rather than API quotas.
  • IBM Db2: No API rate limits; throughput is bounded by instance resources and workload management settings.
