Why teams connect Actian Vector and ClickHouse

Keep tables consistent across Actian Vector and ClickHouse, 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 Actian Vector and ClickHouse 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

  • Publish aggregates computed in Vector back to operational tools that business teams use.
  • Consolidate data from several source systems into one Vector database for BI dashboards.
  • 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.

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.

Migration without a big bang

When one platform is replacing the other, keep tables mirrored while workloads move over gradually, and cut over with nothing to backfill.

What you can sync between Actian Vector 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.

Actian Vector objects ClickHouse objects
Users and Roles Database principals used to grant the sync connection least-privilege access. Views Saved queries used as curated, read-only sync sources.
Databases Top-level containers targeted by a sync connection. Materialized views Insert-time transformations that reshape incoming synced rows into aggregates.
Schemas Namespaces used to organize synced tables. Distributed tables Query-routing tables over cluster shards in self-managed deployments.
Tables Columnar tables that serve as sync sources or destinations. Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs.
Views SQL views readable as query-backed sync sources. Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads.
Columns Typed columns mapped field-by-field during schema mapping. Databases Namespaces that group tables and scope permissions for sync users.

How the Actian Vector and ClickHouse connectors work

Actian Vector

Integration surface
SQL over JDBC/ODBC
Authentication
Database credentials
Change detection
Polling on timestamp or key columns; no log-based CDC interface is generally exposed to external consumers
Capabilities
read · write
Rate limits
No API rate limits in the SaaS sense; throughput depends on cluster resources and query concurrency

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
