DynamoDB CloudWatch Error ConsumedWriteCapacityUnits

Question

I'm getting an error in CloudWatch that is: ConsumedWriteCapacityUnits
The threshold says:
```
ConsumedWriteCapacityUnits < 30 for 15 datapoints within 15 minutes
```
I'm new to DynamoDB.  My website looks up content in this table.  It is very small, both the website and the table, so it is hard to believe I'm over doing anything?   I'm guessing I need to make more "WriteCapacityUnits"?  But I'm not sure how to do that?

Any tips or advice is welcome!

It's telling you that your usage is low. You're not overdoing your usage, rather you're potentially "underdoing". (And thus overpaying.)

You should look at your provisioned capacity for the table and see if it's set too high. Turning on auto-scaling might be helpful because then it will dynamically reduce the provisioned capacity when demand is low. If it's already on, ensure the minimum value it's allowed to scale down to is appropriately low.
