Why teams connect Citus and IBM Db2

Keep Citus 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 Citus 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

  • Consolidate per-tenant rows from distributed tables into per-customer reporting databases.
  • Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.
  • Replicate Db2 tables into a cloud warehouse continuously instead of nightly batch extracts.
  • Keep reference and master data aligned between Db2 and newer cloud databases during modernization projects.

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 Citus 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.

Citus objects IBM Db2 objects
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Indexes Support fast key lookups on sync match columns.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Stored Procedures Existing business logic sometimes invoked as part of write paths.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Sequences ID generation relevant when external systems insert rows.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Tablespaces Physical storage layout that operators consider when adding synced tables.
Views Curated projections over distributed data, often used as read-only sync sources. Databases The connection target; each database holds the schemas a sync addresses.
Sequences Key generators that matter when external writes must not collide with application inserts. Schemas Namespaces separating synced data from application and system objects.

How the Citus and IBM Db2 connectors work

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
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
