Why teams connect Apache Impala and Apache Kylin

Keep tables consistent across Apache Impala and Apache Kylin, for a migration, a multi-warehouse stack, or a dataset two platforms both need.

Apache Kylin is a read-only source: Stacksync reads its data in real time and delivers it into Apache Impala, so Apache Impala always reflects the current state of Apache Kylin — without exports, scripts, or schedulers.

Companies end up with two warehouses for practical reasons: a migration in progress, teams that standardized on different platforms, an acquisition, or tools that only connect to one of them. The result is the same dataset maintained twice, with duplicated pipelines and numbers that almost match.

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.
  • Sync Kylin aggregates into a cloud warehouse to combine them with data Kylin does not cover.
  • Trigger downstream syncs after segment build jobs complete so consumers only read refreshed data.

Migration without a big bang

When one platform is replacing the other, keep tables mirrored while workloads move over gradually, and cut over with nothing to backfill.

Serve tools that only connect to one platform

Mirror the datasets a BI tool, notebook, or application needs onto the platform it can actually reach.

Shared datasets across teams

Where different teams run different warehouses, sync the curated tables both rely on so their metrics agree by construction.

What you can sync between Apache Impala and Apache Kylin

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 Apache Kylin objects
Views Logical views readable as modeled sources. Build Jobs Batch jobs that compute or refresh segments, monitored via the REST API.
Kudu Tables Kudu-backed tables that support row-level insert, update, upsert, and delete. Projects Top-level workspaces that group models, tables, and jobs.
External Tables Tables over files loaded by other tools, queryable without data movement. Models Star-schema definitions over source tables that determine what can be queried.
Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Cubes / Indexes Pre-computed aggregate structures that answer queries at low latency.
Databases Namespaces shared with the Hive Metastore that scope tables. Source Tables Hive or other upstream tables that builds read from.
Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Segments Time-ranged build units that partition pre-computed data.

How the Apache Impala and Apache Kylin 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

Apache Kylin

Integration surface
SQL over JDBC/ODBC plus a REST API for queries and administration
Authentication
Username/password (HTTP basic authentication on the REST API)
Change detection
Not applicable for row-level capture; data freshness follows segment build and refresh jobs, so integrations poll query results
Capabilities
read
Rate limits
No fixed API quotas; query capacity depends on the deployment and pre-computed index coverage
How it works
