Here is a 1-paragraph summary of the text: To determine which plane is disturbing a cat's sleep by utilizing Apache Kafka and KSQL, a streaming SQL engine for Apache Kafka, along with a Raspberry Pi and RTL2832U, a software-defined radio (SDR) device can be used. Raw ADS-B signals are processed on the Raspberry Pi, separated into location update messages or identification messages, and then relayed to Kafka topics using a Confluent REST Proxy. KSQL is used to combine the incoming stream of location data against reference data topics, creating enriched topics such as `location_and_details_stream` and `ident_callsign_stream`. These topics can be used to create dashboards displaying aircraft location on a map, manufacturer information, altitude, and destination routes, allowing for real-time analysis and monitoring.
