Why teams connect IBM Db2 and YugabyteDB

Keep IBM Db2 and YugabyteDB 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 IBM Db2 and YugabyteDB 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 Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.
  • 02 Replicate Db2 tables into a cloud warehouse continuously instead of nightly batch extracts.
  • 03 Consolidate data from regional YugabyteDB clusters into one reporting store.
  • 04 Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.

Common sync patterns

Regional or environment copies

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

Cross-engine sync

Keep the same dataset live in both IBM Db2 and YugabyteDB, 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.

What you can sync between IBM Db2 and YugabyteDB

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.

IBM Db2 objects YugabyteDB objects How this pairing syncs
Schemas Namespaces separating synced data from application and system objects. Schemas Postgres-style namespaces in YSQL used to organize synced data. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Primary read/write target for syncing rows with SaaS systems or other databases. Tables Distributed SQL tables split into tablets; the primary read and write targets. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Indexes Support fast key lookups on sync match columns. Indexes Global secondary indexes maintained transactionally alongside table writes. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences ID generation relevant when external systems insert rows. Sequences ID generation objects relevant when syncing writes into YSQL tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tablespaces Physical storage layout that operators consider when adding synced tables. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors. Tablespaces is specific to IBM Db2 and CDC Streams to YugabyteDB — each maps to any object or custom field on the other side.
Databases The connection target; each database holds the schemas a sync addresses. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively. Databases is specific to IBM Db2 and Databases and Keyspaces to YugabyteDB — each maps to any object or custom field on the other side.

How changes propagate between IBM Db2 and YugabyteDB

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.

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

YugabyteDB IBM Db2 Sub-second propagation

DetectionChanges in YugabyteDB are captured at the source via change data capture — no polling loop against its API. Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors.

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

Rate-limit considerations

  • IBM Db2: No API rate limits; throughput is bounded by instance resources and workload management settings.
  • YugabyteDB: No API rate limits; throughput scales with cluster nodes and tablet distribution.
