Why teams connect ClickHouse and Greenplum

Keep tables consistent across ClickHouse and Greenplum, 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 Greenplum 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.
  • Load operational data from CRMs, ERPs, and production databases into Greenplum for MPP analytics.
  • Publish segments, scores, and aggregates computed in Greenplum back into business tools where teams act on them.

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 ClickHouse and Greenplum

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 Greenplum objects
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Partitions Large tables are commonly partitioned by date, which shapes incremental reads.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Views Read-only projections used to shape data before syncing it out.
Databases Namespaces that group tables and scope permissions for sync users. External tables Reference external files for bulk load paths alongside row-level syncs.
Views Saved queries used as curated, read-only sync sources. Rows Read and written by key; distribution keys determine where rows live.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Databases Top-level containers that scope a sync connection.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Schemas Namespace tables and control which objects a sync can see.

How the ClickHouse and Greenplum 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

Greenplum

Integration surface
PostgreSQL wire protocol (libpq), plus JDBC/ODBC drivers
Authentication
Database credentials
Change detection
Polling with timestamp or key-based cursors; Greenplum does not expose logical-decoding CDC
Capabilities
read · write
Rate limits
Bounded by cluster resources and concurrency settings rather than an API quota.
