Recall & Review

beginner

What is Contributor Insights in DynamoDB?

Contributor Insights is a feature in DynamoDB that helps you identify and analyze the most active contributors to your table's traffic, such as the top keys or partitions causing the most read or write activity.

beginner

How does Contributor Insights help in managing DynamoDB performance?

It helps by showing which keys or partitions are 'hot' or heavily used, so you can optimize your table design or capacity to avoid throttling and improve performance.

intermediate

Which metrics can Contributor Insights track in DynamoDB?

It tracks metrics like the number of read or write requests per partition key, helping you see which keys contribute most to your table's traffic.

intermediate

How do you enable Contributor Insights on a DynamoDB table?

You enable it by creating a Contributor Insights rule on the table or index, specifying the key or attribute to monitor, either via AWS Console, CLI, or SDK.

beginner

What is a common use case for Contributor Insights in DynamoDB?

A common use case is identifying 'hot partitions' that cause uneven traffic, so you can redesign keys or add capacity to handle the load better.

What does Contributor Insights primarily help you identify in DynamoDB?

A Data encryption status

B Backup schedules

C Top contributors to table traffic

D Table schema design

Contributor Insights helps identify the top contributors to your table's traffic, such as hot keys or partitions.

Which of the following is NOT a metric tracked by Contributor Insights?

A CPU usage of DynamoDB servers

B Number of write requests per partition key

C Number of read requests per partition key

D Top partition keys causing traffic

Contributor Insights does not track server CPU usage; it focuses on request counts per key or partition.

How can you enable Contributor Insights on a DynamoDB table?

A By changing the table's encryption settings

B By creating a Contributor Insights rule on the table or index

C By modifying the table's read capacity units

D By exporting the table data to S3

You enable Contributor Insights by creating a rule that specifies which keys or attributes to monitor.

Why is identifying hot partitions important in DynamoDB?

A To improve query speed by indexing

B To enable encryption

C To reduce storage costs

D To avoid throttling and balance traffic

Hot partitions cause uneven traffic and throttling; identifying them helps balance load and improve performance.

Which AWS service feature is Contributor Insights associated with?

A Amazon DynamoDB

B Amazon EC2

C Amazon S3

D Amazon RDS

Contributor Insights is a feature of Amazon DynamoDB to analyze table traffic contributors.
