Why teams connect AWS Aurora MySQL and ClickHouse

Connect AWS Aurora MySQL 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 AWS Aurora MySQL'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 AWS Aurora MySQL where the services that read from it get them at normal query latency.

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

Common use cases

  • Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.
  • Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • Give backend services read and write access to ERP or billing data by syncing it into Aurora tables the application already queries.
  • Stream row changes from Aurora into SaaS tools via binlog CDC instead of scheduled batch exports.

Fresh analytics without loading windows

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

Offload heavy reads

Point analytical queries at the synced copy in ClickHouse and keep AWS Aurora MySQL focused on its operational workload.

Operational data in the warehouse, minus the pipeline

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

What you can sync between AWS Aurora MySQL and ClickHouse

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.

AWS Aurora MySQL objects ClickHouse objects
Columns MySQL data types are mapped to the paired system's field types during schema setup. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates.
Primary keys and indexes Used to match rows across systems and keep incremental syncs efficient. Distributed tables Query-routing tables over cluster shards in self-managed deployments.
Views Can serve as read-only sync sources for derived or filtered datasets. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs.
Foreign keys Express relationships that syncs preserve when mapping to related objects elsewhere. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads.
Stored procedures and triggers Existing database logic keeps firing on rows written by a sync. Databases Namespaces that group tables and scope permissions for sync users.
Databases (schemas) Logical namespaces that scope which tables a sync connection can see. Views Saved queries used as curated, read-only sync sources.

How the AWS Aurora MySQL and ClickHouse connectors work

AWS Aurora MySQL

Integration surface
SQL wire protocol (MySQL-compatible), standard MySQL drivers and JDBC
Authentication
Database credentials, optionally AWS IAM database authentication, over TLS
Change detection
Log-based CDC via the MySQL binary log (binlog), with polling on timestamp columns as a fallback
Capabilities
read · write · CDC

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
