Why teams connect Amazon Redshift and Apache Impala

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

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.

Stacksync syncs tables between Amazon Redshift and Apache Impala continuously, in either or both directions. Rows changed on one platform appear on the other within seconds, with schema and type mapping handled, so both warehouses answer questions with the same data.

Common use cases

  • 01 Feed customer 360 tables built in Redshift to support and success platforms.
  • 02 Centralize CRM, ERP, and product data in Redshift so analysts join it with warehouse tables.
  • 03 Serve fast extracts of Hadoop-resident tables to operational databases and SaaS tools through Impala instead of slow batch engines.
  • 04 Sync mutable reference data into Kudu tables via Impala so row-level updates are possible on the Hadoop side.

Common sync patterns

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 Amazon Redshift and Apache Impala

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.

Amazon Redshift objects Apache Impala objects How this pairing syncs
Databases Top-level containers within a cluster or serverless workgroup. Databases Namespaces shared with the Hive Metastore that scope tables. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Tables Columnar tables used as sync destinations for SaaS and database data. Tables HDFS or object-storage backed tables (commonly Parquet) read at interactive speed. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views SQL views readable as modeled sources for reverse syncs. Views Logical views readable as modeled sources. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Schemas Namespaces used to organize synced tables and control grants. External Tables Tables over files loaded by other tools, queryable without data movement. Schemas is specific to Amazon Redshift and External Tables to Apache Impala — each maps to any object or custom field on the other side.
Materialized Views Precomputed results that downstream syncs can read for performance. Users and Roles Principals (often via Ranger/Sentry) used to grant scoped read access. Materialized Views is specific to Amazon Redshift and Users and Roles to Apache Impala — each maps to any object or custom field on the other side.
External Tables (Spectrum) S3-backed tables queryable through Redshift, readable in syncs. Partitions Partition values used to limit scans and drive incremental reads. External Tables (Spectrum) is specific to Amazon Redshift and Partitions to Apache Impala — each maps to any object or custom field on the other side.

How changes propagate between Amazon Redshift and Apache Impala

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.

Amazon Redshift Apache Impala Interval-based propagation

DetectionStacksync polls Amazon Redshift for changes on an incremental schedule, reading only records changed since the previous pass. Polling or query-based diffing.

DeliveryEach detected change is applied to Apache Impala as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Amazon Redshift: Bounded by cluster or serverless capacity and concurrency settings rather than API quotas.
  • Apache Impala: No API quotas; concurrency is bounded by cluster resources and admission control settings.
