In Liquibase Secure 5.2 and later, drift report generation includes two improvements for large databases:

• Smart report mode — If your database has more than 10,000 changed objects (by default), the report skips the most memory-intensive sections but keeps summaries and object listings. You can adjust this limit if needed.

• Faster processing — Report generation is faster and more memory-efficient for smaller databases.

For most users, this works automatically with no configuration required.

If you are still experiencing OutOfMemoryError exceptions, lower the threshold to trigger the optimized format sooner. Add the following to your liquibase.properties file:

liquibase.reports.drift.maxDetailedObjects=5000

This tells Liquibase to use the lightweight report format when there are more than 5,000 changes (instead of waiting until 10,000).

If you need full detailed reports for large snapshots, increase the threshold. Make sure you have sufficient heap memory available:

liquibase.reports.drift.maxDetailedObjects=50000
