Amazon DynamoDB

Pros

I have used DynamoDB in dozen of projects, including the commercial medium-scale applications and University Research projects that included processing massive amount of data.
DynamoDB is my go-to solution for NoSQL Databases, it is very easy to configure and the documentation is near perfect. An experienced Engineer who has worked with Databases before will grasp most of the features in a couple of weeks. DynamoDB is a fantastic solution that automatically scales and is able to process large amounts of data.

Cons

When used very intensely the cost do rise, but still the costs are comparable to other Cloud Providers' NoSQL solutions like Cassandra, GCP BigTable etc.

Pros

Amazon dynamodb is a NoSql db that supports key value pair. It is easy to configure and use in your java code through some function calls. The access control is excellent and we can easily provide restricted access to different type of users.

Cons

The size of data that dynamodb can store in one key value pair or an item is limited to 400 KB. For large data you have to rely on other storage like S3 and then use that referance location in your dynamodb. That should be supported out of the box in dynamodb.

Pros

We used DynamoDB global tables to replicate data across multiple regions which resulted in a higher level of redundancy.
All this happens in real time to ensure seamless fail over during a disaster while minimising the data lost and it helped in a lot.

Cons

It provides us limited querying options which can be tedious task and the costs for the service can be hard to predict.

Pros

A great scaling NoSQL database on the AWS platform. Easy to administer once you're already using AWS. Integrates great with other services on the platform. Easy to configure security.

Cons

Limited data querying. High entry threshold. Requires understanding because of its differences. It's more difficult with integration when you're not using the AWS platform.

Reasons for Switching to Amazon DynamoDB

Pros

I like how it provides you quick and easy access to data that you need to query. How it stores data in a way that even users without an IT background can quickly have a grasp into is a great thing.

Cons

I like least about it is when querying a lot of data, it won't let you easily sort the dates to show the most recent unless you go over each page there is and go back to the first page.

Pros

One of the biggest benefits of DynamoDB is its scalability. You can easily scale up or down based on your needs, and the service will automatically handle the management and distribution of your data across multiple servers

Cons

While DynamoDB integrates well with other AWS services, it may be more difficult to integrate with non-AWS services or tools.

Pros

1. High performance database with a latency of single digit in seconds 2. Fully managed, all security concerns handled by AWS. 3. Built to support Single Table design 4. Works with most used frameworks. 5. Offers ability of Global tables for scaling into multiple regions

Cons

Since it is not used for Analytical purpose, You really need to understand your data model and have clear access patterns to use DynamoDB at it maximum. If you want to aggregated data like counts of certain records , you need to use an external tool.

Pros

DynamoDB and NoSQL databases in general are really flexible in terms of what and how you store your information. The JSON structure of data makes is easy to work with when integrating with other services like AWS Lambdas and AWS API Gateways.

Cons

There is a steep learning curve for someone coming from a SQL/relational database background. Lots of weird optimization tricks. AWS does not do a good job about letting you know if you accidentally use a reserved word (things just break).

Pros

DynamoDB scales very easily. We don't need to manage resources (CPU, memory, disk) like we used to when using relational databases.

Cons

Using data stored in DynamoDB for analytics is very difficult. Other than syncing data to a separate database for querying, I don't think there's a built-in option for this in DynamoDB.

Pros

+ Very easy to use API
+ fully managed and scalable
+ you only pay per use. There is no infrastructure cost
+ super fast as long as you use query API and not scan API

Cons

+ It's not as flexible as MongoDB when it comes to indexes.
+ Lack of stored procedures as in MongoDB

Pros

Good performance for general storing and retrieving of key-value pair. Managed version has good scalability from AWS.

Cons

Need to know hacky way to further optimize the performance and you don't know if it breaks until you push it.

Pros

Serverless, fully managed, NoSQL, Schemaless, uses key-value pair to store data. Highly scalable and available database.

Cons

Doesn't provide ACID consistency. Need to improve on item size limits, page size limits and partition throughput limits.

Pros

Amazon provides this NoSQL like DB which makes it easier to store and retrieve data. The documenation is well organized which makes it easier to develop applications using DynamoDB

Cons

The query structure seems to be a bit complicated for various fields. The expressions are limited and does not address all business requirements

Pros

Easy to use, speed, compatibility, good documentation for integration, data security. Can easily be integrated with other software.

Cons

The cost is a bit high but overall is worth it.

Pros

DynamoDB has multiple features which can be leveraged for nosql database. I use it within the serverless architecture and it is quite easy to implement in code. The response time of queries is quick and has higher throughput. Read/Write is also inexpensive

Cons

There is a learning curve for those who are not familiar with non rational databases. Also, DynamoDb doesnt support complex joins hence it always needs normalisation on data

Pros

Great tool for managing nosql databases within AWS. Can integrate with a lot of other AWS tools. Queries run fast and is easy to implement

Cons

Can only work with AWS (cannot be deployed on local devices). Can be used only for simple queries.

Pros

The documentation is fantastic and it makes it so easy to get started and creating our proof of concepts.

Cons

Have no real complaints about DynamoDB, it works for us and is easy to use.
