Question 257 Topic 6

Your company has an application running on Google Cloud that is collecting data from thousands of physical devices that
are globally distributed. Data is published to Pub/Sub and streamed in real time into an SSD Cloud Bigtable cluster via a
Dataflow pipeline. The operations team informs you that your Cloud Bigtable cluster has a hotspot, and queries are taking
longer than expected. You need to resolve the problem and prevent it from happening in the future. What should you do?

• A. Advise your clients to use HBase APIs instead of NodeJS APIs.
• B. Delete records older than 30 days.
• C. Review your RowKey strategy and ensure that keys are evenly spread across the alphabet.
• D. Double the number of nodes you currently have.
