Consider a startup that is developing a real$-$time analytics platform analuzing soil samples gathered from IoT devices in the field. This platform is designed to process and visualize data from a vast network of Internet of Things $($IoT$)$ devices dispersed across different geographic areas. The primary objective is to handle and analyze large volumes of data generated by these devices to identify patterns, trends, and anomalies in real$-$time. The collected data encompasses time$-$series metrics related to device performance, environmental and soil conditions, and weather interactions. The analytics team is in search of a database solution that not only scales efficiently but also ensures rapid data retrieval and facilitates complex analytical queries on multi$-$dimensional data.

Given the startup's requirements for a real$-$time analytics platform as described, which NoSQL database type would best suit their needs?
