🎄Twelve Days of SMT 🎄 - Day 9: Cast

The Cast Single Message Transform lets you change the data type of fields in a Kafka message, supporting numerics, string, and boolean. Cast takes one argument listing the field(s) that you would like to transform and the target data type. Multiple fields can be specified by separating each specification with a comma.
