Example 1

json:toObject(json)

The function json:toObject(json) is utilized to convert a JSON string into a corresponding JSON object. When provided with a JSON string, this function parses the string and outputs the JSON object, enabling further operations or manipulations on the JSON object that were not possible with the string format.

Example 2

CREATE STREAM PersonStream (json string);
CREATE SINK STREAM PersonJsonStream (json object);

@info(name = 'ConvertToJson')
INSERT INTO PersonJsonStream
SELECT json:toObject(json) AS json
FROM PersonStream;

This stream worker creates two streams: PersonStream for the input data and PersonJsonStream for the output data.

The ConvertToJson query is structured to process events from the PersonStream. Each event in this stream is a JSON string that contains information about a person.

The function json:toObject(json) is used within the query to convert each JSON string into a corresponding JSON object. The resulting JSON object is then inserted into the PersonJsonStream.

This query operates continuously, processing each person's JSON string details from PersonStream, converting them into JSON objects, and then feeding the JSON objects into PersonJsonStream. This allows for real-time conversion of JSON strings into JSON objects for further processing.
