Builds a Telegram bot in Go that ingests a CSV REST feed every three minutes via curl and kcat into Apache Kafka, normalizes records to protobuf with Schema Registry, and uses ksqlDB to create a stream, a materialized view table keyed by car park name, and both push queries (alerts when empty_places > 500) and pull queries (current empty_places lookups). Integrates Kafka Connect to sink protobuf events to Elasticsearch/Kibana for geo maps and time-series dashboards, and the demo works end-to-end.
