Why teams connect Azure Cosmos DB and SingleStore

Keep Azure Cosmos DB and SingleStore synchronized in real time, across engines, regions, or services, in one or both directions.

Two databases that must agree is one of the oldest problems in engineering: different engines for different workloads, separate services with overlapping reference data, a migration in flight, or regional instances that share a subset of records. Hand-rolled replication across systems means change capture, conflict handling, and type mapping, all built and maintained by your team.

Stacksync syncs tables or collections between Azure Cosmos DB and SingleStore continuously and bi-directionally, translating types between the two engines and resolving conflicts by rules you configure. Rows written on either side appear on the other within seconds.

Common use cases

  • Stream operational documents from Cosmos DB into a SQL warehouse via the change feed for analytics without hitting request-unit budgets with full scans.
  • Sync CRM or ERP records into a Cosmos DB container that backs a customer-facing application.
  • Mirror CRM and SaaS objects into SingleStore tables to serve low-latency operational dashboards.
  • Sync results of real-time analytical queries back into business tools where teams act on them.

Migration with zero-downtime cutover

When one database is replacing the other, sync both directions during the transition and switch traffic when ready, without a freeze window.

Shared reference data between services

Services that own separate databases stay consistent on the records they share, without a custom replication layer.

Regional or environment copies

Mirror selected tables to another region or environment continuously, filtered to just the rows that should travel.

What you can sync between Azure Cosmos DB and SingleStore

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.

Azure Cosmos DB objects SingleStore objects
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Databases The connection target containing the tables a sync addresses.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Tables (rowstore and columnstore) Primary read/write target; storage type affects whether a table suits point lookups or scans.
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Views Read-only projections used as curated sync sources.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Reference Tables Small tables replicated to every node, often used for dimension data in syncs.
Databases Top-level namespaces that scope containers and throughput provisioning. Pipelines Native ingestion jobs from Kafka or object storage that coexist with external syncs.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Stored Procedures Existing logic sometimes invoked on write paths.
