Why teams connect IBM AS/400 and YugabyteDB

Keep IBM AS/400 and YugabyteDB 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 IBM AS/400 and YugabyteDB 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

  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Consolidate data from regional YugabyteDB clusters into one reporting store.
  • Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.

Cross-engine sync

Keep the same dataset live in both IBM AS/400 and YugabyteDB, 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 IBM AS/400 and YugabyteDB

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.

IBM AS/400 objects YugabyteDB objects
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Materialized Views Precomputed query results available in YSQL for read-side shaping.
Libraries The schema-equivalent containers that scope which files a sync reads. Schemas Postgres-style namespaces in YSQL used to organize synced data.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Rows / records The unit of read and write, accessed via SQL or record-level access. Tables Distributed SQL tables split into tablets; the primary read and write targets.
