Using ksqlDB and UDTFs for Infrastructure Monitoring

What this post added

This post introduces the concept and implementation of User-Defined Table Functions (UDTFs) in ksqlDB, specifically demonstrating their use for infrastructure monitoring. It details the process of creating a Java UDTF (`SplitPanel`) to transform raw panel data into individual breaker readings, enriching them with customer information. The post outlines the necessary ksqlDB schema definitions, the Java code for the UDTF, and the deployment process for custom functions.
