Why teams connect Azure Cosmos DB and IBM Db2

Keep Azure Cosmos DB 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 Azure Cosmos DB 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

  • Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.
  • Consolidate documents from multiple containers into a single reporting store.
  • Sync SaaS data into Db2 tables that existing enterprise applications and reports already consume.
  • Replicate Db2 tables into a cloud warehouse continuously instead of nightly batch extracts.

Cross-engine sync

Keep the same dataset live in both Azure Cosmos DB 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 Azure Cosmos DB 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.

Azure Cosmos DB objects IBM Db2 objects
Databases Top-level namespaces that scope containers and throughput provisioning. Indexes Support fast key lookups on sync match columns.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Stored Procedures Existing business logic sometimes invoked as part of write paths.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Sequences ID generation relevant when external systems insert rows.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Tablespaces Physical storage layout that operators consider when adding synced tables.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Databases The connection target; each database holds the schemas a sync addresses.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Schemas Namespaces separating synced data from application and system objects.

How the Azure Cosmos DB and IBM Db2 connectors work

Azure Cosmos DB

Integration surface
REST API and SDKs over HTTPS (API for NoSQL, formerly the SQL API); also MongoDB, Cassandra, Gremlin, and Table API surfaces
Authentication
Account keys, resource tokens, or Microsoft Entra ID role-based access
Change detection
Built-in change feed exposing inserts and updates in order within each partition key range
Capabilities
read · write · CDC

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
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by instance resources and workload management settings
