Why teams connect IBM AS/400 and OpenSearch

Keep IBM AS/400 and OpenSearch 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 OpenSearch 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.
  • Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.
  • Index support tickets and activity logs from SaaS tools for operational dashboards.

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.

Cross-engine sync

Keep the same dataset live in both IBM AS/400 and OpenSearch, so each workload runs on the engine that suits it.

What you can sync between IBM AS/400 and OpenSearch

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 OpenSearch objects
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Ingest pipelines Server-side processors that transform documents as they are written
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Data streams Append-oriented time-series storage for logs and events pushed from source systems
Rows / records The unit of read and write, accessed via SQL or record-level access. Snapshots Backup artifacts, relevant when reseeding an index from a repository
Journals and journal receivers The change log that enables log-based CDC on journaled files. Indexes The core container; synced records land in indexes with defined mappings
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Documents JSON records written via the index and bulk APIs and read via search queries
Libraries The schema-equivalent containers that scope which files a sync reads. Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills

How the IBM AS/400 and OpenSearch connectors work

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.

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas
How it works
