We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"The possibility of managing documents is the most valuable aspect of the solution. I like the fact that I don't have to define the fields.""Its scalability is really good. I can go up to a petabyte of data. It is more of an on-demand use case. I can go from 100 MB to 1 PB if I want, which is very good. Most of the other databases would want you to stick to a specific data allocation. Its subscription cost is lower than similar databases offered by other vendors."

"I like the scalability. There aren't any constraints for posting in the geolocation. I also like the SQL architecture.""I would recommend Cosmos. It made our lives a lot easier. There's not a big learning curve in order to understand the structure and how to use it.""The solution is extremely user-friendly and easy to navigate.""Cosmos DB is stable and easy to use."

Cons
"Querying data on the solution is quite limited, but this is like any other NoSQL database. It's the most common criticism of the NoSQL database in general.""Currently, there is no option for a scheduled refresh in this solution. We want the data to be populated into DynamoDB on a timely basis. Currently, you have to go to the DynamoDB table and hit the refresh button to populate it with the new data. If you have connected DynamoDB to a BI application for creating visualizations with charts, graphs, or other things, you would want it to get updated as per the schedule so that you have updated visualizations in your BI application."

"The query is a little complex. SQL server should have more options. But the query should be better.""We should have more freedom to tweak it and make our own queries for non-traditional use-cases.""It would be ideal if we could integrate Cosmos DB with our Databricks. At this point, that's not possible.""Better documentation on how to integrate with other components would be helpful because I was struggling with this."
