Developed the BackupRestoreCanceler feature for the weaviate/weaviate-go-client repository, enabling users to cancel ongoing backup restore operations for enhanced control and safety in backup workflows. The solution was implemented in Go, utilizing a builder-pattern API that allows configuration of backend, backup ID, and optional bucket or path before executing the cancellation with Do(ctx). Comprehensive end-to-end tests were written to validate the full cancellation flow, including backup creation, restore initiation, cancellation, and status verification. The work focused on API design, backend development, and testing, resulting in a straightforward, ergonomic interface that integrates smoothly with existing backup tooling such as S3.
