What is the primary purpose of an AWS Glue crawler?

To populate the AWS Glue Data Catalog with metadata

A company uses Amazon MSK to ingest data from multiple producers. They have two consumer applications: one for real-time analytics and one for archival to S3. The real-time analytics application requires low latency, while the archival application can tolerate higher latency. They want to ensure that the archival application does not affect the real-time application's performance. Which pattern should they use?

Use a single consumer that writes to both applications.

Use a Kinesis Data Firehose to deliver data to S3 and a separate consumer for real-time.

Use separate consumer groups for each application.

Use a single consumer group for both applications.

A company uses Amazon MSK to stream data from multiple producers. They want to distribute the data to multiple consumer applications, each with different processing requirements. Which pattern should they use to ensure each consumer can read the data independently?

Use a Kinesis Data Analytics application to fan out the data.

Create a separate consumer group for each application.

Use a single consumer group for all applications.

Use a Lambda function to copy data to multiple S3 buckets.
