Why teams connect Exasol and VoltDB

Connect VoltDB and Exasol with one live, two-way sync: operational rows flow into the warehouse, and computed results flow back where systems can read them fast.

Operational databases and analytical warehouses want the same data at different moments. Analysts want VoltDB's rows in Exasol, current and joinable, without a change-data-capture pipeline to maintain. Engineers want the outputs of warehouse work, such as aggregates, features, and segments, available in VoltDB where the services that read from it get them at normal query latency.

Stacksync covers both directions with one connection. Tables or collections in VoltDB sync into Exasol in real time, and result tables in Exasol sync back into VoltDB, with schema and type mapping between the two systems handled for you.

Common use cases

  • Load CRM and ERP records into Exasol tables on a schedule so analysts query fresh operational data.
  • Sync computed metrics or customer segments from Exasol back into a CRM for sales and marketing use (reverse ETL).
  • Keep product, plan, or entitlement state consistent between VoltDB and back-office systems.
  • Push aggregates from VoltDB materialized views into dashboards or operational tools.

Operational data in the warehouse, minus the pipeline

Rows from VoltDB land in Exasol as they change, replacing hand-built CDC and batch extract jobs.

Serve warehouse results at database speed

Aggregates or model outputs computed in Exasol sync into VoltDB, where whatever reads from that database gets them without querying the warehouse.

Fresh analytics without loading windows

Because changes stream continuously, analysts query current data instead of waiting for last night's load.

What you can sync between Exasol 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.

Exasol objects VoltDB objects
UDF scripts In-database functions that can transform synced data after load. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks.
Users and roles Grant read/write access for the dedicated integration account. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target.
Schemas Namespaces that group the tables a sync reads from or writes into. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data.
Tables Primary sync target; columnar relational tables written with standard SQL. Stored Procedures Precompiled transactional units that serve as the primary write interface.
Views Read-only query surfaces often used as curated sources for reverse ETL. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources.
Virtual schemas Federated views over external sources; useful for deciding what needs physical replication. Streams Insert-only constructs that feed the export subsystem with committed rows.

How the Exasol and VoltDB connectors work

Exasol

Integration surface
SQL over JDBC/ODBC drivers and a WebSocket-based client protocol
Authentication
Database credentials (username and password)
Change detection
Polling with timestamp or key columns; Exasol does not expose a transaction-log change feed to clients
Capabilities
read · write
Rate limits
No API quota; concurrency is bounded by cluster resources and session limits

VoltDB

Integration surface
SQL over JDBC plus native client libraries and an HTTP/JSON interface
Authentication
Database credentials
Change detection
Export streams and topics push committed changes to configured targets; otherwise polling
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by partition count and cluster sizing.
