Why teams connect Amazon Redshift and Apache Druid

Keep tables consistent across Amazon Redshift and Apache Druid, 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 Druid 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

  • Feed customer 360 tables built in Redshift to support and success platforms.
  • Centralize CRM, ERP, and product data in Redshift so analysts join it with warehouse tables.
  • Keep lookup tables in Druid refreshed from a CRM or database so query-time joins use current reference data.
  • Expose product telemetry stored in Druid to business tools without granting direct cluster access.

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 Druid

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 Druid objects
Stored Procedures SQL procedures sometimes invoked around load steps. Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid.
Users and Groups Principals used to grant a sync connection scoped access. Lookups Key-value mappings joined at query time, refreshable from external systems.
Databases Top-level containers within a cluster or serverless workgroup. Tasks Batch ingestion and compaction jobs monitored during data loads.
Schemas Namespaces used to organize synced tables and control grants. Datasources The table-like unit of storage and querying, the main target of reads and ingestion.
Tables Columnar tables used as sync destinations for SaaS and database data. Segments Time-partitioned immutable files that hold datasource data; ingestion produces them.
Views SQL views readable as modeled sources for reverse syncs. Dimensions String and categorical columns used for filtering and grouping in synced queries.

How the Amazon Redshift and Apache Druid connectors work

Amazon Redshift

Integration surface
SQL over JDBC/ODBC (PostgreSQL-derived protocol); Redshift Data API over HTTPS
Authentication
Database credentials or IAM-based authentication
Change detection
Polling or query-based diffing; Redshift does not expose a transaction log for external CDC consumers
Capabilities
read · write
Rate limits
Bounded by cluster or serverless capacity and concurrency settings rather than API quotas

Apache Druid

Integration surface
REST API (SQL over HTTP and native JSON queries); JDBC via Avatica
Authentication
Deployment-dependent: basic authentication or an authenticator extension; often fronted by a proxy
Change detection
Not applicable for reads out (polling by time interval); data enters Druid through streaming or batch ingestion rather than row updates
Capabilities
read · write
Rate limits
No fixed API quotas; query concurrency is bounded by broker and historical node capacity
