Why teams connect CockroachDB and IBM AS/400

Keep CockroachDB and IBM AS/400 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 AS/400 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 AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

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 AS/400, 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 CockroachDB and IBM AS/400

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 AS/400 objects
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Libraries The schema-equivalent containers that scope which files a sync reads.
Schemas Namespaces within a database used to isolate synced tables from application tables. Physical files (tables) The Db2 for i tables mapped directly to sync targets.
Tables The core read/write target; rows sync bi-directionally with SaaS objects or other databases. Logical files (views) Indexed or filtered views over physical files, usable as read sources.
Views Read-only projections used as curated sync sources. Members Sub-partitions of files in legacy applications, flattened or selected during syncs.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. Rows / records The unit of read and write, accessed via SQL or record-level access.

How the CockroachDB and IBM AS/400 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 AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.
