Frequently Asked Questions

• How can I optimize migrations for large databases?

For large databases, you can break the migration process into smaller batches. It will help you avoid running complex operations at the peak time of traffic. In addition to that, you can use the indexed columns to speed up the operations. Always test the migrations into the staging environment before applying them to the applications.

• Can migrations affect my application performance?

Yes, migrating the schema can affect your performance sometimes. However, if you are migrating smaller datasets, it often does not hamper your performance or experience. The best practice is to run migrations during the off-time.

• How do I handle schema migrations with zero downtime?

To implement the zero downtime schema migrations, you can use the non-breaking schema changes. You can add new columns and indexes so as not to hamper the application's performance. After that, you can gradually shift the applications to the new schema to minimize the impacts on running time or performance.
