Why teams connect Elasticsearch and IBM AS/400

Keep Elasticsearch 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 Elasticsearch 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

  • Push product catalog data from an ERP or commerce database into Elasticsearch for storefront search.
  • Mirror support tickets into an index used for full-text search and agent-assist tooling.
  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.

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 Elasticsearch 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 Elasticsearch 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.

Elasticsearch objects IBM AS/400 objects
Aliases Stable read/write names that let a sync cut over between index versions without downtime. Physical files (tables) The Db2 for i tables mapped directly to sync targets.
Data streams Append-only targets for time-series or event data pushed from source systems. Logical files (views) Indexed or filtered views over physical files, usable as read sources.
Ingest pipelines Server-side transforms applied to documents as a sync writes them. Members Sub-partitions of files in legacy applications, flattened or selected during syncs.
Index templates Reusable settings and mappings applied automatically to new indices a sync creates. Rows / records The unit of read and write, accessed via SQL or record-level access.
Indices Target containers for synced records; each holds a table-like collection of JSON documents. Journals and journal receivers The change log that enables log-based CDC on journaled files.
Documents The unit of sync; JSON records created, updated, and deleted by _id. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations.

How the Elasticsearch and IBM AS/400 connectors work

Elasticsearch

Integration surface
REST API (JSON over HTTP)
Authentication
API keys or basic authentication; Elastic Cloud also issues service account tokens
Change detection
Polling on timestamp or sequence fields; Elasticsearch does not expose a native change feed or webhooks
Capabilities
read · write
Rate limits
No fixed request quota; throughput is bounded by cluster sizing, thread pools, and bulk queue 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.
How it works

How to connect Elasticsearch to IBM AS/400 — three steps, no code
