Create alarms module for DynamoDB #3

Open erikrj opened 6 months ago

erikrj commented 6 months ago

There is a budding problem, where full table scans are happening in DynamoDB tables. We wanted to somehow block them. Per , we can't disable full table scans, because the gui requires it. After much discussion, we decided a Cloudwatch alarm on spikes in the ConsumedReadCapacityUnits metric is the best approach, and the data systems team should be aware. Review this list of DynamoDB metrics and create a flexible module or library to apply to all DynamoDB tables, using CDK. Observe utilization and performance, and identify any opportunities to construct custom metrics. (Creation is not expected in this ticket, that would be separate, after review of proposed custom metrics.)
