Overview

KillDatasourceDialog is a React dialog component that allows users to permanently delete unused segments for a datasource within a specified time interval.

Description

The KillDatasourceDialog component wraps an AsyncActionDialog to confirm and execute a kill task against the Druid Coordinator API. It issues a DELETE request to remove unused segments for the specified datasource and interval. The dialog provides suggested intervals (defaulting to 24 hours ago to avoid conflicts with streaming ingestion), requires the user to confirm two warning checkboxes acknowledging data loss, and sends the request via the Coordinator's datasource intervals endpoint.

Usage

Used from the datasources view when an administrator wants to permanently delete unused segments and their metadata from deep storage for a specific datasource.
