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

  • 01 Use changefeeds to propagate row changes from a multi-region cluster into a warehouse or search index.
  • 02 Keep reference data consistent between CockroachDB and regional application databases.
  • 03 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 04 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

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 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 How this pairing syncs
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. Changefeeds is specific to CockroachDB and Data queues to IBM AS/400 — each maps to any object or custom field on the other side.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Libraries The schema-equivalent containers that scope which files a sync reads. Databases is specific to CockroachDB and Libraries to IBM AS/400 — each maps to any object or custom field on the other side.
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. Schemas is specific to CockroachDB and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side.
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. Tables is specific to CockroachDB and Logical files (views) to IBM AS/400 — each maps to any object or custom field on the other side.
Views Read-only projections used as curated sync sources. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Views is specific to CockroachDB and Members to IBM AS/400 — each maps to any object or custom field on the other side.
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. Indexes is specific to CockroachDB and Rows / records to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB and IBM AS/400

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.

CockroachDB IBM AS/400 Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

IBM AS/400 CockroachDB Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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

Rate-limit considerations

  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
