Very efficient for application-facing scenarios

There are several areas for improvement. Firstly, having a local development emulator or simulator for Azure Cosmos DB would be beneficial. It would be very handy to have a Docker container that developers can use locally. Although, I know there is a free tier and so on and so forth, having a local environment would be nice. For example, SQL Server is very portable. You can even install it on your machine. That is the number one thing that is missing in Azure Cosmos DB. The second improvement area is the IDE of choice. That means how you interact with Azure Cosmos DB. For example, with SQL Server, you have SQL Server Management Studio. I know there is a little bit of support for Azure Cosmos DB in Azure Data Studio, but it is not heavily advertised or it does not feel like first-class citizen support. Developer experience or developer tooling is missing in terms of interacting with the database. Better developer tools or an IDE for interacting with Azure Cosmos DB would enhance the developer experience. Lastly, there is some mixed messaging about what Azure Cosmos DB is, given its multiple APIs. There are so many Azure Cosmos DB APIs available. There is NoSQL. There are MongoDB, Gremlin, and others. There is still some mixed messaging for others who are new to Azure Cosmos DB about what Azure Cosmos DB is. Is this like MongoDB, but then there is also MongoDB in Azure Cosmos DB? I know it well, and I know that the default one is just NoSQL, but others I have interacted with over the last ten years or so get confused.

Used to get data from the database faster

Rockset is an easy tool, and anyone can use it. The solution provides some type of data grouping. This grouping of data based on some parameters is not simple, but it is very useful. I would recommend the solution to other users. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"Microsoft Azure Cosmos DB is easy to use and implement for application programmers."

"rate Azure support nine out of 10. They respond quickly and will help you manage costs. However, they mainly give you an overview of the issue, so they'll never have an in-depth idea of what you're doing. They aren't the owners of our product, so they don't know much about it, but they can ask you generally: What are you doing? Are you doing too many updates? How can we reduce the cost?"

"The global synchronization feature of Azure Cosmos DB stands out as the most valuable for me."

"Microsoft Azure Cosmos DB simplifies the process of saving and retrieving data."

"The connectors, such as the MongoDB connector and the integration with SQL, are incredibly valuable."

"Microsoft Azure Cosmos DB is very fast. Data retrieval and data storage are very quick."

"The latency and availability of Microsoft Azure Cosmos DB are fantastic."

"The features most valuable to us in Microsoft Azure Cosmos DB are the auto scale and change feed. These features allow us to do some operations that are not possible with SQL Server."

More Microsoft Azure Cosmos DB pros

"The initial setup was very simple."

"Rockset is very fast, and you can query just like in MySQL."

Cons

"There is room for improvement in terms of stability."

"The challenge for us is always scale."

"It would be beneficial if Cosmos supported batch and real-time use cases to make the system more seamless."

"Overall, it works very well and fits the purpose regardless of the target application. However, by default, there is a threshold to accommodate bulk or large requests."

"We expect Cosmos DB to lead on that. There is potential for improved security features, which is important for data storage, especially for Dell Technologies."

"The initial setup was difficult."

"It's still new, and good training resources are harder to find. Even the most recent books on Cosmos DB are several years old, which is ancient in IT terms."

"We would like to see advancements in AI with the ability to benchmark vector search capabilities, ensuring it answers questions accurately. During our initial implementation, we faced challenges with indexing and sorting, which are natively available in other offerings but required specific configurations in Cosmos."

More Microsoft Azure Cosmos DB cons

"Rockset is now bought by OpenAI. It’s uncertain if Rockset will continue to exist as it is."

"Filtering the database based on indexes is difficult in Rockset and should be simplified."

Pricing and Cost Advice

"Microsoft Azure Cosmos DB pricing is based on RUs. Reading 1 KB document costs one RU, whereas writing one document costs five RUs. Pricing for querying depends on the complexity of the query. If you increase the document size, it will automatically increase the RU cost."

"The pricing for Cosmos DB has improved, particularly with the new pricing for Autoscale."

"The solution is very expensive."

"Everything could always be cheaper. I like that Cosmos DB allows us to auto-scale instead of pre-provisioning a certain capacity. It automatically scales to the demand, so we only pay for what we consume."

"I would rate Cosmos DB's cost at seven out of ten, with ten being the highest."

"Pricing is one of the solution's main features because it is based on usage, scales automatically, and is not too costly."

"With heavy use, like a large-scale IoT implementation, you could easily hit a quarter of a million dollars a month in Azure charges if Cosmos DB is a big part of it."

"Its pricing structure is quite flexible."
