Evaluates the 'jsonPath' on jsonField, returns the result as the type 'resultsType', use optional defaultValuefor null or parsing error.

Extracts all matched JSON field keys based on 'jsonPath' into a STRING_ARRAY.

Extracts the field from the DATETIME expression of the format 'YYYY-MM-DD HH:MM:SS'. Currently this transformation function supports YEAR, MONTH, DAY, HOUR, MINUTE, and SECOND fields.

Convert object to JSON String

Extracts the object value from jsonField based on 'jsonPath', the result type is inferred based on JSON value. Cannot be used in query because data type is not specified.

Extracts the Long value from jsonField based on 'jsonPath', use optional defaultValuefor null or parsing error.

Extracts the Double value from jsonField based on 'jsonPath', use optional defaultValuefor null or parsing error.

Extracts the String value from jsonField based on 'jsonPath', use optional defaultValuefor null or parsing error.

Extracts an array from jsonField based on 'jsonPath', the result type is inferred based on JSON value. Cannot be used in query because data type is not specified.

Extracts an array from jsonField based on 'jsonPath', the result type is inferred based on JSON value. Returns empty array for null or parsing error. Cannot be used in query because data type is not specified.

MAP_VALUE Select the value for a key from Map stored in Pinot. MAP_VALUE(mapColumn, 'myKey', valueColumn)

The transform function will filter the value from the multi-valued column with the given constant values. The VALUEIN transform function is especially useful when the same multi-valued column is both filtering column and grouping column.
