Question
A company wants to improve user satisfaction for its smart home system by adding more features to its recommendation engine. Each sensor asynchronously pushes its nested JSON data into Amazon Kinesis Data Streams using the Kinesis Producer Library (KPL) in Java. Statistics from a set of failed sensors showed that, when a sensor is malfunctioning, its recorded data is not always sent to the cloud. The company needs a solution that offers near-real-time analytics on the data from the most updated sensors. Which solution enables the company to meet these requirements?
Options
- ASet the RecordMaxBufferedTime property of the KPL to "-1" to disable the buffering on the sensor
- BUpdate the sensors code to use the PutRecord/PutRecords call from the Kinesis Data Streams
- CSet the RecordMaxBufferedTime property of the KPL to "0" to disable the buffering on the sensor
- DUpdate the sensors code to use the PutRecord/PutRecords call from the Kinesis Data Streams
