Why teams connect CockroachDB and SAP Hana

Keep CockroachDB and SAP Hana 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 CockroachDB and SAP Hana 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

  • 01 Consolidate data from several SaaS tools into one distributed SQL store that survives zone failures.
  • 02 Write application events from CockroachDB back to CRM fields to give go-to-market teams product context.
  • 03 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.
  • 04 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.

Common sync patterns

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.

Cross-engine sync

Keep the same dataset live in both CockroachDB and SAP Hana, so each workload runs on the engine that suits it.

What you can sync between CockroachDB and SAP Hana

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.

CockroachDB objects SAP Hana objects How this pairing syncs
Schemas Namespaces within a database used to isolate synced tables from application tables. Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Sequences ID generators that matter when writes originate from an external system. Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Views Read-only projections used as curated sync sources. System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. Views is specific to CockroachDB and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.
Indexes Secondary indexes that keep sync lookup queries fast on key columns. System views (SYS schema) Catalog and monitoring views such as SYS.TABLES and TABLE_COLUMNS; read to discover schema and auto-generate field mappings for new tables. Indexes is specific to CockroachDB and System views (SYS schema) to SAP Hana — each maps to any object or custom field on the other side.
Changefeeds Built-in CDC streams that emit row-level changes to external sinks. Column store tables HANA's default table type, optimized for analytics; synced two-way as rows over the SQL interface with the primary key driving upserts and delete tracking. Changefeeds is specific to CockroachDB and Column store tables to SAP Hana — each maps to any object or custom field on the other side.
Databases Logical containers a sync connects to, addressed like PostgreSQL databases. Row store tables OLTP-oriented tables held fully in memory; read and written the same way through the SAP HANA client for high-write operational tables. Databases is specific to CockroachDB and Row store tables to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between CockroachDB and SAP Hana

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

CockroachDB SAP Hana Sub-second propagation

DetectionChanges in CockroachDB are captured at the source via change data capture — no polling loop against its API. CDC via changefeeds, which stream row-level changes.

DeliveryEach detected change is applied to SAP Hana as a row-level write, with types converted between the two schemas.

SAP Hana CockroachDB Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

DeliveryEach detected change is applied to CockroachDB as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • CockroachDB: No API rate limits in the SaaS sense; throughput is bounded by cluster capacity.
  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.
