Download Apache Solr JDBC Driver

Download the Apache Solr JDBC driver, copy the JDBC URL into DbSchema, and start designing schemas with ER diagrams — free Community Edition.

About the Apache Solr JDBC driver

A JDBC driver is a Java .jar library that lets applications connect to Apache Solr. 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.

JDBC URL format

Host, port, database name, and SSL options are passed in a URL starting with jdbc:. Each Apache Solr driver uses its own syntax — see the connection details below.

The Apache Solr JDBC driver

Apache Solr is an open-source enterprise search platform built on Apache Lucene, providing full-text search, faceted search, and rich document indexing. It is used widely for e-commerce, log analytics, and content discovery applications requiring flexible, schema-free document storage. Solr's SQL interface via Streaming Expressions allows standard SQL queries over collections.

The Apache Solr JDBC URL

• Required File(s): solr-solrj-xxx.jar
• Java Driver Class: org.apache.solr.client.solrj.io.sql.DriverImpl
• JDBC URL: jdbc:solr://{HOST}:{PORT}?collection={COLLECTION}
• Website: Apache Solr

The JDBC driver uses the Streaming Expressions SQL interface. The SolrJ library (included with Solr) provides the driver. SolrCloud mode is required for full SQL support; ZooKeeper connectivity may also be needed when connecting to a SolrCloud cluster rather than a standalone Solr instance.

DbSchema and Apache Solr

DbSchema uses the SolrJ JDBC driver to connect to Apache Solr, enabling schema visualization of Solr collections and SQL query execution via the streaming expressions interface. Ideal for teams who need a visual tool to understand their Solr index schemas.
