Question 88 of 100 | ← Chapter 1
A data engineer notices that Amazon Athena queries are held in a queue before the queries run. How can the data engineer prevent the queries from queueing?
- A. Increase the query result limit.
- B. Configure provisioned capacity for an existing workgroup. ✓
- C. Use federated queries.
- D. Allow users who run the Athena queries to an existing workgroup
Correct Answer: B. Configure provisioned capacity for an existing workgroup.
Explanation
在AmazonAthena中,查询在执行前会进入一个队列,这通常是因为Athena是按照需求分配资源的。为了防止查询排队,可以预先为工作组配置预留容量(ProvisionedCapacity),这样就可以确保有足够的资源来立即执行查询,而不需要等待资源可用。因此,选项B“为现有工作组配置预留容量”是正确的答案。
