Question
A developer used the AWS SDK to create an application that aggregates and produces log records for 10 services. The application delivers data to an Amazon Kinesis Data Streams stream. Each record contains a log message with a service name, creation timestamp, and other log information. The stream has 15 shards in provisioned capacity mode. The stream uses service name as the partition key. The developer notices that when all the services are producing logs, ProvisionedThroughputExceededException errors occur during PutRecord requests. The stream metrics show that the write capacity the applications uses is below the provisioned capacity. Which solution will most effectively resolve the throttling issue?
Options
- AChange the capacity mode from provisioned to on-demand.
- BDouble the number of shards until the throttling errors stop occurring.
- CChange the partition key from service name to creation timestamp.
- DUse a separate Kinesis stream for each service to generate the logs.
