Why teams connect CockroachDB and IBM Db2

Keep CockroachDB 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 CockroachDB 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

  • Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • Keep reference data consistent between CockroachDB and regional application databases.
  • Expose Db2 records that back core business systems to a CRM so sales and support see order or account state.
  • Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.

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.

Cross-engine sync

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

What you can sync between CockroachDB 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.

CockroachDB objects IBM Db2 objects
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Stored Procedures Existing business logic sometimes invoked as part of write paths.
Schemas Namespaces within a database used to isolate synced tables from application tables. Sequences ID generation relevant when external systems insert rows.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Tablespaces Physical storage layout that operators consider when adding synced tables.
Views Read-only projections used as curated sync sources. Databases The connection target; each database holds the schemas a sync addresses.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Schemas Namespaces separating synced data from application and system objects.
Sequences ID generators that matter when writes originate from an external system. Tables Primary read/write target for syncing rows with SaaS systems or other databases.

How the CockroachDB and IBM Db2 connectors work

CockroachDB

Integration surface
SQL wire protocol (PostgreSQL-compatible)
Authentication
Database credentials with TLS; client certificates or SCRAM password auth
Change detection
CDC via changefeeds, which stream row-level changes; polling as a fallback
Capabilities
read · write · CDC
Rate limits
No API rate limits in the SaaS sense; throughput is bounded by cluster capacity

IBM Db2

Integration surface
SQL via JDBC/ODBC/CLI drivers; optional REST endpoints in some editions
Authentication
Database credentials, typically backed by OS or LDAP authentication
Change detection
Log-based CDC through IBM's replication tooling where licensed; otherwise polling on timestamp or audit columns
Capabilities
