An enterprise is collecting data produced by thousands of temperature sensors and processing it using Amazon Kinesis Data Streams and AWS Lambda. Each day, devices produce between 10 and 12 million records, but Lambda processes only around 450 thousand of them. Amazon CloudWatch shows that Lambda is not throttled.

What should be done to guarantee the processing of all data? (Select two.)

A. Increase the BatchSize value on the EventSource, and increase the memory allocated to the Lambda function.
B. Decrease the BatchSize value on the EventSource, and increase the memory allocated to the Lambda function.
C. Create multiple Lambda functions that will consume the same Amazon Kinesis stream.
D. Increase the number of vCores allocated for the Lambda function.
E. Increase the number of shards on the Amazon Kinesis stream.
