是否可以在AWS ElastiCache集群中停止节点 [英] Is it possible to stop nodes in AWS ElastiCache cluster

问题描述

我有一个用于开发的AWS账户.由于开发人员位于一个时区，因此我们会在数小时后关闭资源以节省使用量.

I have an AWS account which is used for development. Because the developers are in one timezone, we switch off the resources after hours to conserve usage.

是否可以暂时关闭Elasticache群集中的节点?我在cli参考中找到的全部是删除群集": http://docs.aws.amazon.com/cli/latest/reference/elasticache/index.html

Is it possible to temporarily switch off nodes in elasticache cluster? all i found in cli reference was 'delete cluster': http://docs.aws.amazon.com/cli/latest/reference/elasticache/index.html

推荐答案

目前没有办法在同一位置上停止和EMR群集 感觉您可以使用EC2实例. EMR群集使用实例存储 音量和EC2启动/停止功能依赖于EBS的使用 不适用于高性能，低延迟的卷 HDFS利用率.

At this time there is not a way to STOP and EMR cluster in the same sense you can with EC2 instances. The EMR cluster uses instance-store volumes and the EC2 start/stop feature relies on the use of EBS volumes which are not appropriate for high-performance, low-latency HDFS utilization.

模拟此行为的最佳方法是将数据存储在S3和 然后将其作为集群的启动步骤，然后保存回 S3完成后.

The best way to simulate this behavior is to store the data in S3 and then just ingest as a start up step of the cluster then save back to S3 when done.

如果要维护相同的dns，则可以使用API​​/CLI更新弹性群集.

If you want to maintain the same dns, you can use the API/CLI to update the elastic cluster.
