KSQL, a streaming SQL engine for Apache Kafka, enables sophisticated stream processing on Kafka topics through an interactive SQL interface. This article demonstrates how to set up a sandbox environment using Confluent Platform to explore KSQL with Twitter as a demo data source. The process involves ingesting tweets via a Kafka Connect Twitter Connector, defining schemas, and executing SQL queries to filter, transform, and aggregate data. The article highlights the power of KSQL to handle unbounded streaming data by creating continuous queries and aggregates, converting streams into tables, and managing late-arriving data. It showcases KSQL's capabilities in transforming raw streaming data into structured insights, emphasizing its utility in building robust stream processing applications.
