Topic 2 Question 71
Which of the following is NOT a valid use case to select HDD (hard disk drives) as the storage for Google Cloud Bigtable?
You expect to store at least 10 TB of data.
You will mostly run batch workloads with scans and writes, rather than frequently executing random reads of a small number of rows.
You need to integrate with Google BigQuery.
You will not use the data to back a user-facing or latency-sensitive application.
解説
For example, if you plan to store extensive historical data for a large number of remote-sensing devices and then use the data to generate daily reports, the cost savings for HDD storage may justify the performance tradeoff. On the other hand, if you plan to use the data to display a real-time dashboard, it probably would not make sense to use HDD storagereads would be much more frequent in this case, and reads are much slower with HDD storage.

The correct answer is C. HDD storage is suitable for use cases that meet the following criteria:
You expect to store at least 10 TB of data. You will not use the data to back a user-facing or latency-sensitive application. Your workload falls into one of the following categories:
Batch workloads with scans and writes, and no more than occasional random reads of a small number of rows or point reads. Data archival, where you write very large amounts of data and rarely read that data. https://cloud.google.com/bigtable/docs/choosing-ssd-hdd#use-cases-hdd
