Why teams connect Apache Impala and IBM AS/400

Connect IBM AS/400 and Apache Impala with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want IBM AS/400's rows in Apache Impala, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in IBM AS/400 where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in IBM AS/400 sync into Apache Impala in real time, and result tables in Apache Impala sync back into IBM AS/400, with schema and type mapping between the two systems handled for you.

Common use cases

  • Sync mutable reference data into Kudu tables via Impala so row-level updates are possible on the Hadoop side.
  • Read new partitions incrementally from Parquet tables and land them in a cloud warehouse during migration.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

Offload heavy reads

Point analytical queries at the synced copy in Apache Impala and keep IBM AS/400 focused on its operational workload.

Operational data in the warehouse, minus the pipeline

Rows from IBM AS/400 land in Apache Impala as they change, replacing hand-built CDC and batch extract jobs.

What you can sync between Apache Impala 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.

Apache Impala objects IBM AS/400 objects
Kudu Tables Kudu-backed tables that support row-level insert, update, upsert, and delete. Journals and journal receivers The change log that enables log-based CDC on journaled files.
External Tables Tables over files loaded by other tools, queryable without data movement. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations.
Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Libraries The schema-equivalent containers that scope which files a sync reads.
Databases Namespaces shared with the Hive Metastore that scope tables. Physical files (tables) The Db2 for i tables mapped directly to sync targets.
Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Logical files (views) Indexed or filtered views over physical files, usable as read sources.
Partitions Partition values used to limit scans and drive incremental reads. Members Sub-partitions of files in legacy applications, flattened or selected during syncs.

How the Apache Impala and IBM AS/400 connectors work

Apache Impala

Integration surface
SQL over JDBC/ODBC (HiveServer2-compatible protocol)
Authentication
Deployment-dependent: Kerberos, LDAP, or username/password
Change detection
Polling on partition or timestamp columns; no change log exposed for external consumers
Capabilities
read · write
Rate limits
No API quotas; concurrency is bounded by cluster resources and admission control settings

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.
