JSON Parser Stage

JSON parsing converts JSON content from a single document field into one or more new documents. This parser uses Solr’s JsonRecordReader to split JSON into sub-documents.

When entering configuration values in the UI, use unescaped characters, such as \t for the tab character. When entering configuration values in the API, use escaped characters, such as \\t for the tab character.
Enter the root path in Unix command-line format, not JSON format. For example, enter /response/docs, not $['response']['docs'].

Parses JSON documents with optional splitting and mappings

id - string

Default: 8ed0f713-0b14-44e3-a037-cbeeeaf394a8

label - string

A label for this Parser Stage

<= 255 characters

enabled - boolean

Default: true

mediaTypes - array[string]

Documents with a media type on this list will be matched by this parser stage. See inheritMediaTypes / use default media types for more.

inheritMediaTypes - boolean

Each parser stage has a built-in list of media types it handles by default. If this setting is true, that list will be used along with any optional additional types provided in the mediaTypes list. If this setting is false, this stage will only be selected for media types in the mediaTypes list, and the mediaTypes list becomes a mandatory property which must have at least one valid media type.

Default: true

ignoredMediaTypes - array[string]

Documents with a media type on this list will be not be processed by this parser stage.

pathPatterns - array[object]

Specify a file name or pattern that must be matched for this parser stage to run. Forward slashes ("/") are used to join names of files inside archives with the archive name.

object attributes:{syntax : {
display name: Pattern type
type: string
}pattern : {
display name: File name or pattern
type: string
}}

errorHandling - string

Default: mark

Allowed values: ignorelogfailmark

outputFieldPrefix - string

Fields extracted by this parser will be prefixed with this string. The remainder of the field name will be as detected in the stream

<= 20 characters

Match pattern: ^$|^[A-Za-z_][A-Za-z0-9_\-\.]+$

rootPath - string

Use only children of this JSON pointer.

includePath - boolean

Include parent element names when using a root path.

Default: false

splitArrays - boolean

First split top-level arrays into multiple documents, and then apply other rules.

Default: true

expectJsonL - boolean

Expect the input to contain multiple line separated JSON documents

Default: false

maxLineSize - integer

Set maximum size of a line in bytes. This is important for processing JsonL with large documents.

Default: 8192

mappings - array[object]

Extract parts of the document into specified fields

object attributes:{path required : {
display name: JSONPath expression
type: string
}target required : {
display name: Target field
type: string
}}

listHandling - string

Create a single multivalued field containing all items, or a separate index-numbered field per list item?

Default: multivalued

Allowed values: multivaluedindex_numbered

type - stringrequired

Default: json

Allowed values: json
