Download Google AlloyDB JDBC Driver
What Is a JDBC Driver?
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 Google AlloyDB, so you never have to write low-level socket code. Drivers are typically distributed by the database vendor or as open-source projects.
Understanding the JDBC URL
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 Google AlloyDB are listed in the section below.

Google AlloyDB is a fully managed, PostgreSQL-compatible database service on Google Cloud, combining the familiarity of PostgreSQL with Google's advanced storage and computing technologies. It is designed for demanding transactional and analytical workloads, offering up to 4× faster transactional throughput and 100× faster analytical queries than standard PostgreSQL. AlloyDB includes a built-in columnar engine and supports the pgvector extension for AI-powered similarity search.
Google AlloyDB JDBC Driver Details
- Required File(s): postgresql-xxx.jar (PostgreSQL JDBC Driver)
- Java Driver Class: org.postgresql.Driver
- JDBC URL: jdbc:postgresql://{HOST}:{PORT}/{DB}
- Website: Google AlloyDB
AlloyDB uses standard PostgreSQL port 5432. Connect via the AlloyDB Auth Proxy for secure access outside your VPC, or use Private Service Connect for VPC-internal connectivity. The standard PostgreSQL JDBC driver is fully compatible with AlloyDB's PostgreSQL-compatible interface.
DbSchema and Google AlloyDB
DbSchema connects to Google AlloyDB using the standard PostgreSQL JDBC driver, visualizing AlloyDB's PostgreSQL-compatible schemas including columnar engine acceleration and pgvector extension tables, supporting both OLTP design and analytical workload optimization.

Explore Google AlloyDB Visually with DbSchema
Once the JDBC driver is configured, DbSchema connects to your Google AlloyDB 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 Google AlloyDB 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 Google AlloyDB 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.
Relational Data Explorer
Browse Google AlloyDB 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.
Schema Synchronization
Compare your Google AlloyDB 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.
SQL Editor
Write and execute Google AlloyDB 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.
HTML Schema Documentation
Generate a static HTML site documenting every table, column, type, index, and relationship in your Google AlloyDB schema. Share it with your team or embed it in your project wiki — no extra tooling required.
