The ability to store multiple data attributes is crucial. For example, in a contact flow, if a customer calls, we can integrate DynamoDB dynamically. We need only the customer's mobile number as the primary key, which is stored in the DynamoDB table.

I would rate customer service as seven because the process we must follow can be lengthy. Sometimes we cannot connect with the correct team to resolve issues.

The only challenge I face with Amazon DynamoDB is that with the partition key and secondary key, the query doesn't become very easy.

Previously, only 64 KB could be used, and later, I think, it was about 400 KB. If the tool could have an additional 10 MB to offer, then the tool could be easier to use.

If you purchase the support plan, their support team is good. If not, it takes two to three days to respond, sometimes even more.

In future releases, I would like a feature that lets us store information about public holidays or weekends. When customers call during those closed periods, we could use DynamoDB to trigger an automatic message. So this would eliminate the need for agents to manually inform customers.
