Why teams connect Apache Druid and Apache Pinot

Keep tables consistent across Apache Druid and Apache Pinot, 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 Apache Druid and Apache Pinot 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

  • 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.
  • Push reference and dimension data into Pinot via batch segment loads to enrich event queries.
  • Sync Pinot aggregates into a warehouse to join low-latency metrics with modeled historical data.

Consolidation after M&A

Bring the acquired company's warehouse data across continuously instead of through one-off dumps.

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.

What you can sync between Apache Druid and Apache Pinot

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 Druid objects Apache Pinot objects
Dimensions String and categorical columns used for filtering and grouping in synced queries. Offline Tables Batch-loaded tables merged with real-time data at query time.
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Indexes Inverted, range, and star-tree indexes that determine which sync queries run at low latency.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. Tenants Logical groupings that isolate workloads on shared clusters.
Lookups Key-value mappings joined at query time, refreshable from external systems. Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target.
Tasks Batch ingestion and compaction jobs monitored during data loads. Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup.
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Segments Immutable data files that batch ingestion uploads and the cluster serves.

How the Apache Druid and Apache Pinot connectors work

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

Apache Pinot

Integration surface
REST API (SQL queries via the broker; administration via the controller); JDBC client available
Authentication
Deployment-dependent: HTTP basic authentication or token-based auth where enabled
Change detection
Not applicable for reads out (polling by time column); data enters Pinot via streaming ingestion or segment upload, not row-level writes
Capabilities
read · write
Rate limits
No fixed API quotas; query throughput depends on broker and server sizing
