🎄 Twelve Days of SMT 🎄 - Day 9: Cast

Read Original

This technical article details the 'Cast' Single Message Transform (SMT) for Apache Kafka Connect. It demonstrates how to transform field data types (e.g., string to int16/float32) within Kafka messages, using Avro/Protobuf schemas. It includes configuration examples, schema inspection via REST API, and discusses applying the transform at source or sink connectors for correct data handling.
