Why teams connect ClickHouse and YugabyteDB

Connect YugabyteDB and ClickHouse 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 ClickHouse, 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 ClickHouse in real time, and result tables in ClickHouse sync back into YugabyteDB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • Consolidate data from regional YugabyteDB clusters into one reporting store.
  • Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.

Operational data in the warehouse, minus the pipeline

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

Serve warehouse results at database speed

Aggregates or model outputs computed in ClickHouse 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 ClickHouse 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.

ClickHouse objects YugabyteDB objects
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Schemas Postgres-style namespaces in YSQL used to organize synced data.
Databases Namespaces that group tables and scope permissions for sync users. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Views Saved queries used as curated, read-only sync sources. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Tables Distributed SQL tables split into tablets; the primary read and write targets.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Indexes Global secondary indexes maintained transactionally alongside table writes.

How the ClickHouse and YugabyteDB connectors work

ClickHouse

Integration surface
Native TCP protocol and HTTP interface; standard SQL dialect, with MySQL and PostgreSQL wire compatibility available
Authentication
Database credentials (username/password); ClickHouse Cloud issues per-service credentials over TLS
Change detection
No log-based CDC for consumers; incremental reads use polling on monotonic columns, and ClickHouse is usually the destination rather than the source
Capabilities
read · write

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.
