Why teams connect Couchbase and IBM AS/400
Keep Couchbase 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 Couchbase 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 Write cleaned or enriched records from operational databases back into Couchbase collections that applications read.
- 02 Sync Couchbase JSON documents into Postgres or a warehouse where analysts work with flattened relational tables.
- 03 Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
- 04 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
Common sync patterns
Cross-engine sync
Keep the same dataset live in both Couchbase 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.
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 Couchbase 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.
| Couchbase objects | IBM AS/400 objects | How this pairing syncs | |
|---|---|---|---|
| JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. | Journals and journal receivers The change log that enables log-based CDC on journaled files. | JSON Documents is specific to Couchbase and Journals and journal receivers to IBM AS/400 — each maps to any object or custom field on the other side. | |
| Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. | Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. | Global Secondary Indexes is specific to Couchbase and Data queues to IBM AS/400 — each maps to any object or custom field on the other side. | |
| XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. | Libraries The schema-equivalent containers that scope which files a sync reads. | XDCR replications is specific to Couchbase and Libraries to IBM AS/400 — each maps to any object or custom field on the other side. | |
| Full-text search indexes Search indexes over documents, relevant when syncing searchable content. | Physical files (tables) The Db2 for i tables mapped directly to sync targets. | Full-text search indexes is specific to Couchbase and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side. | |
| Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. | Logical files (views) Indexed or filtered views over physical files, usable as read sources. | Buckets is specific to Couchbase and Logical files (views) to IBM AS/400 — each maps to any object or custom field on the other side. | |
| Scopes Namespaces inside a bucket used to group collections, similar to schemas. | Members Sub-partitions of files in legacy applications, flattened or selected during syncs. | Scopes is specific to Couchbase and Members to IBM AS/400 — each maps to any object or custom field on the other side. |
How changes propagate between Couchbase 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.
Couchbase IBM AS/400 Sub-second propagation
DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.
DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.
IBM AS/400 Couchbase 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 Couchbase as a row-level write, with types converted between the two schemas.
Rate-limit considerations
- Couchbase: Throughput is bounded by cluster sizing rather than API rate limits.
- IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.

FAQ
Couchbase and IBM AS/400 integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Couchbase and IBM AS/400: authenticate both systems, choose the objects to sync (such as Couchbase's JSON Documents and Global Secondary Indexes), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Couchbase: SQL++ (N1QL) query service, key-value SDK APIs, and REST management APIs. Authentication: Database credentials with role-based access control, typically over TLS. IBM AS/400: 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). Stacksync manages authentication, retries, and rate limits on both sides.
-
Couchbase: The Database Change Protocol (DCP) exposes an ordered stream of document mutations, and it is the same mechanism Couchbase's own XDCR replication and Kafka connector consume. IBM AS/400: The integrated database is Db2 for i; tables are physical files organized into libraries, with logical files acting as views. Stacksync's field mapping accounts for these differences between Couchbase and IBM AS/400 without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Couchbase and IBM AS/400 records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Couchbase and IBM AS/400 connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Couchbase–IBM AS/400 integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Couchbase and IBM AS/400. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
