Implementation:Apache Druid Publication Config Form

Knowledge Sources	Apache Druid
Domains	Data_Ingestion, Data_Management
Last Updated	2026-02-10 00:00 GMT

Overview

Concrete form-based UI pattern for configuring the target datasource name and write mode in the batch ingestion wizard.

Description

The publication settings step renders form controls for the datasource name (text input) and append toggle (switch). These values modify spec.spec.dataSchema.dataSource and spec.spec.ioConfig.appendToExisting in the ingestion spec.

This is a pure configuration form with no API calls — the publication target is used when the spec is submitted to the Druid Overlord.

Usage

Import this as part of the LoadDataView publication step. Rendered after tuning parameters and before spec review.
