Overview

Defines comprehensive JSON autocompletion rules for ingestion task and supervisor spec editing in the Druid web console.

Description

INGESTION_SPEC_COMPLETIONS is a large constant array of JsonCompletionRule objects (912 lines) that provides context-aware autocompletion for the full ingestion specification JSON editor. It covers both batch ingestion tasks (index_parallel, index, index_hadoop) and streaming supervisors (kafka, kinesis, rabbit, autocompact). The rules span the complete ingestion spec hierarchy: root-level type and spec, dataSchema (timestampSpec, dimensionsSpec, metricsSpec, granularitySpec, transformSpec), ioConfig (inputSource, inputFormat), and tuningConfig (partitionsSpec). A helper function isSupervisorType is used to conditionally show supervisor-only properties such as suspended.

Usage

This module is consumed by the load data view, which passes the completions array to a JsonInput component when users are authoring or editing ingestion spec JSON directly.

Name	Type	Description
INGESTION_SPEC_COMPLETIONS	JsonCompletionRule[]	Array of completion rules covering the full ingestion spec hierarchy: root type/spec, dataSchema (dataSource, timestampSpec, dimensionsSpec, metricsSpec, granularitySpec, transformSpec), ioConfig (inputSource types like local, http, inline, s3, gcs, azure, hdfs; inputFormat types like csv, tsv, json, parquet, orc, avro_stream), tuningConfig (partitionsSpec types: dynamic, hashed, range), and conditional properties for supervisor types (kafka, kinesis, rabbit)

  setError={setJsonError}
  jsonCompletions={INGESTION_SPEC_COMPLETIONS}
/>
