A recent trend we’ve been observing is customers using DynamoDB to power their serverless applications. This enables a table or a global secondary index to increase its provisioned read and write capacity to handle sudden increases in traffic, without throttling. Schedule settings can be adjusted in serverless.yml file. I was wondering if it is possible to re-use the scalable targets When you modify the auto scaling settings on a table’s read or write throughput, it automatically creates/updates CloudWatch alarms for that table – four for writes and four for reads. As you can see from the screenshot below, DynamoDB auto scaling uses CloudWatch alarms to trigger scaling actions. Even though you might have multiple non-production environments, but having one stackdriver project per application-env is overkill. Lastly, scroll all the way down and click Create. Every global secondary index has its own provisioned throughput capacity, separate from that of its base table. Even if you’re not around, DynamoDB Auto Scaling will be monitoring your tables and indexes to automatically adjust throughput in response to changes in application traffic.
