Reviews of Amazon DynamoDB
Alternatives Considered:
DynamoDB for Big Data Processing
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.
The goto NoSql db that one should go to for easy and fast access
Comments: Overall the experience have been very good. It's very easy to understand. We had switched from mongodb NoSql db to Amazon dynamodb and comparatively it was easy to migrate.
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.
Amazon DynamoDB for Software Engineers
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.
Alternatives Considered:
Java developer on Amazon DynamoDB.
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.
DynamoDB Review
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.
