Using Liquibase with Vertica

Vertica is an column-oriented analytic database and query engine. For more information, see Vertica Documentation.

Supported versions

  • 12.0.X
  • 11.1.X

Verification level

Unverified: Liquibase does not have enough information to know how well this extension or integration works.

Note: A database's verification level indicates how well it works with different features in Liquibase and across different products, such as Liquibase Community and Liquibase Pro. For more information, see Liquibase Database Tutorials.

Prerequisites

Install drivers

To use Liquibase and Vertica, you need two JAR files:

Place your JAR file(s) in the liquibase/lib directory. Read more: Adding and Updating Liquibase Drivers.

If you use Maven, you must include the driver JAR as a dependency in your pom.xml file. Read more: Configuring Liquibase Attributes in your Maven POM File.

<dependency>
    <groupId>com.vertica</groupId>
    <artifactId>vertica-jdbc</artifactId>
    <version>12.0.0-0</version>
</dependency>
<dependency>
    <groupId>org.liquibase.ext</groupId>
    <artifactId>liquibase-vertica</artifactId>
    <version>4.16.1</version>
</dependency>

Test your connection

  1. Ensure your Vertica database is configured. See the Vertica Quickstart Guide for more information.
  2. Specify the database URL in the Liquibase properties file. Liquibase does not parse the URL. You can either specify the full database connection string or specify the URL using your database's standard JDBC format:
  3. url: jdbc:vertica://localhost:5433/docker

    Tip: To apply a Liquibase Pro key to your project, add the following property to the Liquibase properties file: liquibaseProLicenseKey: <paste code here>

  1. Create a text file called changelog (.xml, .sql, .json, or .yaml) in your project directory and add a changeset.
  2. Navigate to your project folder in the CLI and run the Liquibase status command to see whether the connection is successful:
  3. liquibase --username=test --password=test --changelog-file=<changelog.xml> status

    Note: You can pass arguments in the CLI or keep them in the Liquibase properties file.

  4. Inspect the SQL with the update-sql command. Then make changes to your database with the update command.
  5. liquibase --changelog-file=<changelog.xml> update-sql
    liquibase --changelog-file=<changelog.xml> update
  6. From a database UI tool, ensure that your database contains the test_table you added along with the DATABASECHANGELOG table and DATABASECHANGELOGLOCK table.
