Offers exceptional performance to users
Previously, when in my company, we used to store 64 KB of data, we used to get problems and errors, and due to such reason, at such a point in time, we had to find a different storage system or modify the system so that the size of the value is not more than 64 KB. The main aforementioned issue in the tool can be considered for improvement for Amazon DynamoDB. In our company, we have some data which can be stored as we want. 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. The tool is a key value storage, where the key will be long. In terms of value, we couldn't store more than 64 kb previously in the tool, but later on, it was increased to 400 KB, which is a limitation that I don't like in the tool.

Useful pattern identification, price well, and straightforward implementation
Relational databases are never good at identifying patterns in graphs or other similar relationships, whereas Amazon Neptune is. Amazon Neptune is good for identifying fraud and many banks are using it. For example, know that I go to certain places all the time that are connected with nodes and edges, such as gas stations, shops, and Amazon. Since people are creatures of habit, the banks can use those nodes and edges to make a model of where I like to shop and spend money. If they see something pop up that's out of character for me, then they know immediately that it is possible fraud. They can determine this because a purchase I made was somewhere I never go or because of geography.

Quotes from Members

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

Pros

"The latency feature is precious."
"Stability-wise, I rate the solution a ten out of ten. I've never faced any problems."
"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."
"It is a NoSQL product."
"Amazon DynamoDB is a fully managed service by AWS, and it is designed to provide fast and predictable performance."
"The best feature of the solution is that it is a NoSQL database."
"The best feature is NoSQL."
"Scalability has significantly enhanced data retrieval speeds."
"Relational databases are never good at identifying patterns in graphs or other similar relationships, whereas Amazon Neptune is."
"The initial setup is actually simple."
 

Cons

"As more data comes in, it becomes more expensive."
"I would rate the stability a seven out of ten. We faced some configuration issues."
"The solution's initial setup is a bit complex if you want it for something more specific."
"The solution's interface is the biggest challenge because if you want to access DynamoDB, you need an AWS account."
"If you have no prior experience with this type of non-relational database, the syntaxes, implementation, or understanding may be difficult."
"Defining simple expressions and queries can be slightly complicated due to DynamoDB's unique JSON syntax. This can be confusing, especially for beginners."
"The design patterns and the documentation for this solution could be improved. In a future release, we would like to see an improvement of the data push options as we sometimes experience blockers when moving data."
"The pricing model should be improved"
"Amazon Neptune could improve by spreading more awareness for others to have an understanding of the solution because the technology is fairly new. The developer community and larger community do not understand it yet."
"In my scenario, the integration wasn't easy because ................in Java."
 

Pricing and Cost Advice

"Amazon DynamoDB is a cheap solution."
"The solution's pricing is good, and it's not expensive."
"The solution is cheaper than Cosmos DB."
"It's an expensive solution"
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven. It is not the cheapest, but it is not the costliest either."
"It is costly. To reduce the costs, users need to read the node in front of it. For read-heavy groups, cache optimization can help manage costs.I can't disclose specific pricing, but it's competitive compared to others in the market, and this information is easily accessible online"
"I can say that it is not the cheapest one because if we had our own kind of storage solution, our own hosting, and instead of using the cloud, we opted for some other method, it would have been a tool of a lower cost."
"The product is expensive"
"Microsoft Azure and Amazon AWS are on par for pricing and Google has been raising its prices."
