Download Dremio JDBC Driver

What Is a JDBC Driver?

A JDBC driver is a Java library file (.jar) that enables Java applications to communicate with a database. The JDBC is a standard interface implemented by each database with a specific driver. Drivers are typically distributed by the database vendor or as open-source projects.

Understanding the JDBC URL

The connection parameters including the database location, database name and connection method are passed to the driver using the JDBC URL. The JDBC URL is a text starting with 'jdbc:...' which combines the hostname, port, database name, and any driver-specific parameters. The exact syntax can be different for each JDBC driver.

The Dremio JDBC Driver

Dremio is a lakehouse platform that provides high-speed SQL query execution directly on cloud object storage such as S3, ADLS, and GCS without data movement. It acts as a semantic layer over heterogeneous data sources, enabling self-service analytics with fast reflections and data virtualization. Dremio supports Apache Arrow Flight SQL for high-throughput data transfer.

The Dremio JDBC URL

  • Required File(s): dremio-jdbc-driver-xxx.jar
  • Java Driver Class: com.dremio.jdbc.Driver
  • JDBC URL: jdbc:dremio:direct={HOST}:{PORT}
  • Website: Dremio

Connect to the Dremio coordinator on port 31010 (Arrow Flight SQL port). Authentication uses Dremio username and password. For ZooKeeper-based discovery in distributed mode, use jdbc:dremio:zk=zkhost/dremio as the connection URL instead.

DbSchema and Dremio

DbSchema connects to Dremio using the Dremio JDBC driver, enabling visualization of virtual dataset schemas from S3, ADLS, and other data sources, and SQL query execution against Dremio's lakehouse engine through the built-in SQL editor.

Explore Dremio Visually with DbSchema

Once the JDBC driver is configured, DbSchema connects to your Dremio database and gives you a full graphical workbench — no command-line required. Available as a free Community Edition and a full-featured PRO Edition. No registration needed to get started.

Interactive ER Diagrams

Reverse-engineer your Dremio schema into a drag-and-drop ER diagram. Arrange tables visually, add new columns, define foreign keys, and let DbSchema generate the DDL — all without writing SQL by hand.

Visual Query Builder

Compose Dremio queries by clicking on tables and columns — no SQL knowledge required. Add joins, filters, groupings, and aggregations through a point-and-click interface, then copy the generated SQL or run it directly against the live database.
