A JDBC driver is a Java library file (.jar) that enables Java applications — including DbSchema — to communicate with a database over a standard API. The driver translates generic JDBC calls into the network protocol understood by Apache Solr, so you never have to write low-level socket code. Drivers are typically distributed by the database vendor or as open-source projects.
Every JDBC driver identifies the target database through a connection URL. The URL encodes the hostname, port, database name, and any driver-specific parameters as a single string. The exact syntax varies per driver — the details for Apache Solr are listed in the section below.
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 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 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.

Once the JDBC driver is configured, DbSchema connects to your Apache Solr 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.
Reverse-engineer your Apache Solr 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.
Compose Apache Solr 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.
Browse Apache Solr table data and follow foreign key relationships across tables in a single view. Edit cells inline, filter rows, and paginate through large datasets — all without leaving the explorer.
Compare your Apache Solr schema across development, staging, and production environments. DbSchema generates the exact ALTER statements needed to close the gap and lets you review every change before executing — reducing the risk of unintended schema drift.
Write and execute Apache Solr queries in the integrated SQL editor with schema-aware autocomplete, syntax highlighting, and instant result display. Run scripts, inspect execution plans, and export results to CSV or JSON from a single interface.
Generate a static HTML site documenting every table, column, type, index, and relationship in your Apache Solr schema. Share it with your team or embed it in your project wiki — no extra tooling required.
