Question 1

How do I install SchemaHero on Kubernetes?

Accepted Answer

The recommended method is using the kubectl plugin; you can also deploy via Helm or YAML manifests. The documentation provides detailed steps for installation and configuration in your cluster.

Question 2

Does SchemaHero work with Amazon RDS or other cloud databases?

Accepted Answer

Yes, SchemaHero can manage external databases like Amazon RDS. You need to configure connection details as Kubernetes secrets, and it will apply schema changes remotely.

Question 3

SchemaHero vs Liquibase: which should I use?

Accepted Answer

SchemaHero is Kubernetes-native and declarative, ideal for GitOps workflows. Liquibase is more general-purpose and script-based. Choose SchemaHero if you're fully invested in Kubernetes; otherwise, Liquibase offers broader environment support.

Question 4

Can SchemaHero handle rollbacks of schema changes?

Accepted Answer

Yes, by reverting YAML definitions to a previous version, SchemaHero can generate rollback migrations. However, effectiveness depends on database support for reversible ALTER TABLE operations, and manual checks may be needed.

Question 5

How does SchemaHero manage data type changes or column renaming?

Accepted Answer

SchemaHero generates standard ALTER TABLE statements for such changes. For complex data migrations, you might need to supplement with custom scripts, as it focuses on schema structure rather than data manipulation.

Question 6

Is SchemaHero suitable for production databases with high availability?

Accepted Answer

Yes, but with caution. It's designed for production use, but you should test migrations in staging first. The automated approach ensures consistency, but complex changes require thorough review to avoid downtime.
