Why teams connect ClickHouse and Materialize

Keep tables consistent across ClickHouse and Materialize, 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 ClickHouse and Materialize 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

  • 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.
  • Drive alerting and operational tooling from SUBSCRIBE change streams instead of scheduled queries.
  • Maintain real-time inventory, usage, or account-health counters consumed by customer-facing 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 ClickHouse and Materialize

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 Materialize objects
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Clusters Compute pools that isolate ingestion, view maintenance, and serving.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Connections & Secrets Stored credentials and endpoints used by sources and sinks.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Schemas & Databases Namespaces that organize objects a sync targets.
Databases Namespaces that group tables and scope permissions for sync users. Tables User-managed tables that accept INSERT/UPDATE/DELETE from sync pipelines.
Views Saved queries used as curated, read-only sync sources. Sources Ingestion points (Kafka, Postgres CDC, MySQL CDC, webhook) that feed external data into Materialize.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Materialized Views Incrementally maintained query results that syncs read as continuously up-to-date datasets.

How the ClickHouse and Materialize 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
