field.convert

Convert the type of a field.

Description​

Convert takes the field of one type and converts it into another type (e.g. string to integer). The applicable types are string, int, float and bool. Converting can be done between any combination of types. Note that booleans will be converted to numeric values 1 (true) and 0 (false). Processor is only applicable to .Key, .Payload.Before and .Payload.After prefixes, and only applicable if said fields contain structured data. If the record contains raw JSON data, then use the processor json.decode to parse it into structured data first.
