Prabin Silwal - PeerSpot reviewer
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

"Capable of auto-scaling and integrates easily with other tools"
"The transactions are very fast, and the cost is low with Amazon DynamoDB."
"The technical support team is always available to help us."
"Offers a vital query-handling feature"
"It offers quick performance and rapid data retrieval, often providing limited data initially but scaling up to fulfill larger demands seamlessly."
"We switched to DynamoDB from a relational database that would've had scale problems and would've cost a lot of money to run at scale. DynamoDB allows us to match expense to usage. When not many people are using and it's a quiet day, there is a low cost. On a busy day, there is a higher cost. We get good performance along the way and less maintenance on the database."
"Amazon DynamoDB is a NoSQL database that stores unstructured data and provides high performance."
"Being serverless, it alleviates concerns about scalability and failover."
"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."
"Data integrity across availability zones would be a valuable addition. Currently, DynamoDB provides eventual consistency across availability zones, but strong consistency would be beneficial for certain use cases."
"The documentation is not good enough."
"The solution's efficiency and performance should be faster than other databases."
"Having an import option, whether through browsing or local file uploads, would significantly improve the efficiency of data migration, enabling users to swiftly transfer large volumes of data into DynamoDB."
"Support is better if using a paid version."
"I initially faced issues with the solution's stability, performance, and security."
"If the database is kept running continuously, extra costs will be incurred. This particular area needs enhancement."
"In my scenario, the integration wasn't easy because ................in Java."
"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."
 

Pricing and Cost Advice

"The solution is cheaper than Cosmos DB."
"I would rate the pricing for this solution a four out of five."
"Given the services and benefits provided by AWS, the solution's pricing is average."
"We previously paid around $20,000 a month for MongoDB, and now we're paying just $4,000 monthly for Amazon DynamoDB."
"Amazon DynamoDB is a cheap solution."
"Amazon DynamoDB is cheap."
"It's an expensive solution"
"It is a little expensive."
"Microsoft Azure and Amazon AWS are on par for pricing and Google has been raising its prices."
