Why teams connect OpenSearch and SAP Hana

Keep OpenSearch 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 OpenSearch 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 Index support tickets and activity logs from SaaS tools for operational dashboards.
  • 02 Backfill or rebuild indexes from a database after mapping changes without hand-written ETL.
  • 03 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.
  • 04 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.

Common sync patterns

Cross-engine sync

Keep the same dataset live in both OpenSearch 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.

Shared reference data between services

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

What you can sync between OpenSearch 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.

OpenSearch objects SAP Hana objects How this pairing syncs
Documents JSON records written via the index and bulk APIs and read via search queries 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. Documents is specific to OpenSearch and System views (SYS schema) to SAP Hana — each maps to any object or custom field on the other side.
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills 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. Index aliases is specific to OpenSearch and Column store tables to SAP Hana — each maps to any object or custom field on the other side.
Index templates Mapping and settings presets applied to new indexes a sync creates 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. Index templates is specific to OpenSearch and Row store tables to SAP Hana — each maps to any object or custom field on the other side.
Ingest pipelines Server-side processors that transform documents as they are written Calculation views Modeled analytic views over base tables; read-only sources for pushing aggregated or joined results into a warehouse or downstream app. Ingest pipelines is specific to OpenSearch and Calculation views to SAP Hana — each maps to any object or custom field on the other side.
Data streams Append-oriented time-series storage for logs and events pushed from source systems SQL views Standard database views; read-only projections synced outbound when the source data should not be exposed as raw base tables. Data streams is specific to OpenSearch and SQL views to SAP Hana — each maps to any object or custom field on the other side.
Snapshots Backup artifacts, relevant when reseeding an index from a repository Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Snapshots is specific to OpenSearch and Schemas to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between OpenSearch 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.

OpenSearch SAP Hana Interval-based propagation

DetectionStacksync polls OpenSearch for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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

SAP Hana OpenSearch 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 OpenSearch through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • OpenSearch: Throughput bounded by cluster sizing rather than fixed 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.

SAP Hana

Integration surface
SQL over the SAP HANA client (JDBC/ODBC drivers); OData/REST via XS for app-layer access
Authentication
Dedicated database user credentials over an encrypted TLS connection (password sent hashed); Kerberos, SAML, JWT, and X.509 certificate authentication are also supported. SAP HANA Cloud enforces TLS and IP allowlisting.
