Why teams connect SAP Hana and VoltDB

Keep SAP Hana and VoltDB 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 SAP Hana and VoltDB 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 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.
  • 02 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.
  • 03 Stream committed VoltDB results out through export targets into a warehouse for historical analysis.
  • 04 Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.

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

What you can sync between SAP Hana and VoltDB

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.

SAP Hana objects VoltDB objects How this pairing syncs
Calculation views Modeled analytic views over base tables; read-only sources for pushing aggregated or joined results into a warehouse or downstream app. Stored Procedures Precompiled transactional units that serve as the primary write interface. Calculation views is specific to SAP Hana and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.
SQL views Standard database views; read-only projections synced outbound when the source data should not be exposed as raw base tables. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. SQL views is specific to SAP Hana and Materialized Views to VoltDB — each maps to any object or custom field on the other side.
Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Streams Insert-only constructs that feed the export subsystem with committed rows. Schemas is specific to SAP Hana and Streams to VoltDB — each maps to any object or custom field on the other side.
Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Sequences is specific to SAP Hana and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side.
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. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Triggers is specific to SAP Hana and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side.
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. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. System-versioned temporal tables is specific to SAP Hana and Replicated Tables to VoltDB — each maps to any object or custom field on the other side.

How changes propagate between SAP Hana and VoltDB

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.

SAP Hana VoltDB 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 VoltDB as a row-level write, with types converted between the two schemas.

VoltDB SAP Hana Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

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

Rate-limit considerations

  • 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.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.

How the SAP Hana and VoltDB connectors work

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.
Change detection
Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table; system-versioned temporal tables and SLT/SDI provide trigger- and log-based CDC. No native webhooks.
