Why teams connect RavenDB and SAP Hana

Keep RavenDB 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 RavenDB 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 documents from distributed RavenDB clusters into one reporting store.
  • 02 Keep external search indexes or caches current from RavenDB change feeds without custom pollers.
  • 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

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 RavenDB and SAP Hana, so each workload runs on the engine that suits it.

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.

What you can sync between RavenDB 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.

RavenDB objects SAP Hana objects How this pairing syncs
Data subscriptions Server-side change feeds that push matching documents to consumers Calculation views Modeled analytic views over base tables; read-only sources for pushing aggregated or joined results into a warehouse or downstream app. Data subscriptions is specific to RavenDB and Calculation views to SAP Hana — each maps to any object or custom field on the other side.
Documents JSON records, the primary unit read and written during sync SQL views Standard database views; read-only projections synced outbound when the source data should not be exposed as raw base tables. Documents is specific to RavenDB and SQL views to SAP Hana — each maps to any object or custom field on the other side.
Collections Groupings of documents by type, mapped to tables in relational targets Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Collections is specific to RavenDB and Schemas to SAP Hana — each maps to any object or custom field on the other side.
Indexes Static and auto indexes used to query documents for filtered reads Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Indexes is specific to RavenDB and Sequences to SAP Hana — each maps to any object or custom field on the other side.
Attachments Binary payloads stored with documents, handled separately from the JSON body Triggers AFTER INSERT/UPDATE/DELETE triggers capture changes into a shadow/logging table so updates and deletes are detected near-real-time without full scans. Attachments is specific to RavenDB and Triggers to SAP Hana — each maps to any object or custom field on the other side.
Revisions Historical versions of documents, useful for audit-oriented replication 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. Revisions is specific to RavenDB and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between RavenDB 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.

RavenDB SAP Hana Sub-second propagation

DetectionChanges in RavenDB are captured at the source via change data capture — no polling loop against its API. Data subscriptions and the Changes API provide server-pushed change feeds.

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

SAP Hana RavenDB 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 written to RavenDB through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • RavenDB: Throughput bounded by cluster resources rather than API quotas.
  • 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.
