Why teams connect Apache Druid and YugabyteDB

Connect YugabyteDB and Apache Druid with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want YugabyteDB's rows in Apache Druid, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in YugabyteDB where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in YugabyteDB sync into Apache Druid in real time, and result tables in Apache Druid sync back into YugabyteDB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Query aggregated event metrics from Druid and sync them into CRM account fields for usage-based selling.
  • Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
  • Sync reference data such as pricing or entitlements from an ERP into YugabyteDB for globally distributed low-latency reads.
  • Consolidate data from regional YugabyteDB clusters into one reporting store.

Operational data in the warehouse, minus the pipeline

Rows from YugabyteDB land in Apache Druid as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Apache Druid sync into YugabyteDB, where whatever reads from that database gets them without querying the warehouse.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

What you can sync between Apache Druid and YugabyteDB

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 YugabyteDB objects
Metrics Numeric columns, often pre-aggregated at ingestion via rollup. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.
Lookups Key-value mappings joined at query time, refreshable from external systems. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Tasks Batch ingestion and compaction jobs monitored during data loads. Tables Distributed SQL tables split into tablets; the primary read and write targets.
Datasources The table-like unit of storage and querying, the main target of reads and ingestion. Indexes Global secondary indexes maintained transactionally alongside table writes.
Segments Time-partitioned immutable files that hold datasource data; ingestion produces them. Materialized Views Precomputed query results available in YSQL for read-side shaping.

How the Apache Druid and YugabyteDB 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

YugabyteDB

Integration surface
SQL wire protocol (PostgreSQL-compatible YSQL) plus a Cassandra-compatible YCQL API
Authentication
Database credentials
Change detection
Native CDC from the write-ahead log via PostgreSQL logical replication or Debezium-compatible connectors
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput scales with cluster nodes and tablet distribution.
