JSON Parser
The JavaScript Object Notation (JSON) Parser reads JSON data and extracts key values from the fields with valid JSON field values of normalized logs. A string filter is applied to the provided field, which defines a path for extracting values from it. The filter contains a key, which can be alphanumeric and special characters except square brackets ([]), backtick (`) and tilde (~). These exceptional characters are reserved for essential use cases, such as mapping the list and selecting a condition in JSON Parser.
