Download the VoltDB JDBC driver, copy the JDBC URL into DbSchema, and start designing schemas with ER diagrams — free Community Edition.
A JDBC driver is a Java .jar library that lets applications connect to VoltDB.
DbSchema uses JDBC to reverse engineer schemas, run SQL, and generate documentation.
Driver files are usually published by the database vendor or an open-source project.
Host, port, database name, and SSL options are passed in a URL starting with jdbc:.
Each VoltDB driver uses its own syntax — see the connection details below.
VoltDB is an in-memory NewSQL database engineered for high-throughput, low-latency transactional workloads that require deterministic performance at scale. It uses a shared-nothing, horizontally partitioned architecture and processes transactions through stored procedures to minimize latency. VoltDB is used in telecommunications, financial services, and real-time analytics applications.
VoltDB uses port 21212 for the JDBC interface. Authentication with username and password can be specified in the URL or connection properties. The VoltDB JDBC driver is included in the VoltDB client distribution.
DbSchema connects to VoltDB using the VoltDB JDBC driver, allowing visualization of VoltDB's in-memory schema including partitioned tables and stored procedures, SQL query execution, and interactive data exploration for high-throughput transactional workloads.
Connect VoltDB, build your first ER diagram in minutes. No account required.
Get the VoltDB driver zip below and install DbSchema for Windows, macOS, or Linux.
In DbSchema, open Driver Manager, add the extracted JAR, and paste your JDBC URL.
Reverse engineer VoltDB, edit the model visually, and publish schema documentation.
After the JDBC driver connects, you get ER diagrams, SQL editor, schema sync, and HTML documentation in one desktop app. Compare DbSchema editions.
Reverse engineer VoltDB into an interactive diagram and edit structures visually.
Run SQL with autocomplete or compose queries without writing every join by hand.
Export HTML docs your team can browse without installing DbSchema.

Other drivers teams often configure alongside VoltDB.
Teams working with VoltDB often use these engines too. Explore dedicated guides and JDBC setup for each.
