Which of the following would you use as the partition key?

A company is building a traffic monitoring system. The system would be monitoring the traffic along 4 highways. The system would be responsible for producing a time series-based analysis report for each highway.

The traffic sensors on each highway have been configured to send its data to Azure Event Hubs. The data from Event Hubs is then consumed by three departments. Each department makes use of an Azure Web App to display the data.

You have to implement the Azure Event Hub instance. You need to implement a solution which ensures data throughput is maximized and latency is minimized.

Which of the following would you use as the partition key?
A . Highway
B . Department
C . Timestamp
D . Datestamp

Answer: A

Explanation:

Since the data would come in for each highway, the highway represented by probably a highway number would be ideal for the partition key.

The other options are incorrect since they would not provide ideal values for the distribution of data across the partitions.
