Why teams connect Apache Druid and Rockset

Keep tables consistent across Apache Druid and Rockset, 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 Rockset 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 operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
  • Sync Druid query results into a warehouse to combine real-time aggregates with historical models.
  • Sync Postgres or DynamoDB tables into collections for low-latency aggregations without loading a batch warehouse.
  • Read query results back into an operational database to expose computed metrics to applications.

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.

Consolidation after M&A

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

What you can sync between Apache Druid and Rockset

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 Rockset objects
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Integrations Managed source connections (databases, streams, object storage) feeding collections.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. Virtual Instances Isolated compute units that separate ingest from query workloads.
Lookups Key-value mappings joined at query time, refreshable from external systems. Collections Schemaless document containers that ingested and synced records land in.
Tasks Batch ingestion and compaction jobs monitored during data loads. Documents JSON records addressable by _id, written via the Write API in sync pipelines.
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Workspaces Namespaces that group collections and query lambdas per team or environment.
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Query Lambdas Named, parameterized SQL queries invoked over REST to read synced data.

How the Apache Druid and Rockset 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

Rockset

Integration surface
REST API (SQL over HTTP, plus a document Write API)
Authentication
API key
Change detection
Polling via SQL queries on timestamp fields; ingestion-side change capture is handled by Rockset's managed source connectors
Capabilities
read · write
