BookingSync, the company behind Smily, is a French startup. When we created the BookingSync product, our vacation rental management platform, the goal was to make the lives of vacation rental owners, managers, and agencies much easier. We strove to help them save time and book more so they could spend more time with the ones they love. As we added many powerful features, our platform became more oriented to managers and agencies.

Apache Kafka is a distributed event store and stream-processing platform. It is an open-source system developed by the Apache Software Foundation written in Java and Scala. The project aims to provide a unified, high-throughput, low-latency platform for handling real-time data feeds. Kafka can connect to external systems (for data import/export) via Kafka Connect, and provides the Kafka Streams libraries for stream processing applications.
