Struct JsonParserConfig

pub struct JsonParserConfig {
    pub update_format: JsonUpdateFormat,
    pub json_flavor: JsonFlavor,
    pub array: bool,
    pub lines: JsonLines,
}

JSON parser configuration.

Describes the shape of an input JSON stream.

Examples

A configuration with update_format="raw" and array=false is used to parse a stream of JSON objects without any envelope that get inserted in the input table.

{"b": false, "i": 100, "s": "foo"}
{"b": true, "i": 5, "s": "bar"}

A configuration with update_format="insert_delete" and array=false is used to parse a stream of JSON data change events in the insert/delete format:

{"delete": {"b": false, "i": 15, "s": ""}}
{"insert": {"b": false, "i": 100, "s": "foo"}}

A configuration with update_format="insert_delete" and array=true is used to parse a stream of JSON arrays where each array contains multiple data change events in the insert/delete format.

[{"insert": {"b": true, "i": 0}}, {"delete": {"b": false, "i": 100, "s": "foo"}}]

Fields

update_format: JsonUpdateFormat

JSON update format.

json_flavor: JsonFlavor

Specifies JSON encoding used for individual table records.

array: bool

Set to true if updates in this stream are packaged into JSON arrays.

Example

[{"b": true, "i": 0},{"b": false, "i": 100, "s": "foo"}]

lines: JsonLines

Whether JSON elements can span multiple lines.

This only affects JSON input.
