7 Answers to Your Questions About Amazon DynamoDB


Amazon DynamoDB

You’ve probably got a lot of questions before deciding to use Amazon DynamoDB. What is Amazon DynamoDB? could be one of them. What distinguishes DynamoDB from MySQL? Advantages of Using DynamoDB? as well as more complex ones We’ve answered 7 of these questions for you in this blog post. 

What is Amazon DynamoDB?

Amazon DynamoDB is a fully managed proprietary NoSQL database service that delivers fast and predictable performance while also allowing for seamless scalability. It is compatible with key-value and document data structures. Users can use DynamoDB to create tables for your database that can store and retrieve any amount of data and support any request traffic level.

What type of database is Amazon DynamoDB?

Amazon DynamoDB is a fully managed, serverless key-value NoSQL database that can run high-performance applications at any scale. DynamoDB includes built-in security, in-memory caching, automatic multi-region replication and data export tools. In other words, Amazon DynamoDB is a fully managed proprietary NoSQL database service that delivers fast and predictable performance while also allowing for seamless scalability. It is compatible with key-value and document data structures. Users can use DynamoDB to create tables for your database that can store and retrieve any amount of data and support any request traffic level. 

What are the Benefits of Amazon DynamoDB?

Performance and Scalability

Developers can meet customer demand by combining incremental scalability and high performance with the ease of cloud administration, reliability, and table data model provided by Amazon DynamoDB. It can scale the table assets to a large number of servers across multiple Availability Zones to meet storage requirements. Furthermore, there is no specific limit to the amount of data that a table can store. As a result, any amount of data can be stored and retrieved, and Dynamo DB shared data across more servers as the amount of data in a table increased.

TTL (Time to Live)

TTL is a process that allows you to specify a specific timestamp for deleting expired data from your tables. As soon as the timestamp expires, the item associated with it is marked as expired and removed from the table. You won’t have to manually track down and delete expired data if you use this feature. TTL can assist you in reducing storage usage and the cost of storing data that is no longer needed.

Cross-region Replication

It allows you to keep identical copies of a DynamoDB master table as replicas in one or more AWS regions. When cross-region replication is enabled for a table, replicas of the table are produced in other AWS regions. Any mode of change in the table will be propagated to all replicas as a result.

Fine-grained Access Control

Fine-Grained Access Control provides the owner of a DynamoDB table with extensive control over the data in the table. The table owner, in particular, can specify who has access to which data or attributes of the table and who can perform which actions, such as read-write or update. AWS Identity and Access Management, which manages security credentials and permissions, is used in conjunction with Fine-Grained Access Control.

What is Amazon DynamoDB streams?

DynamoDB Streams is a compelling service that can be combined with other AWS services to overcome a variety of problems. When DynamoDB Streams is enabled, it records a time-ordered sequence of changes in an item-level in a DynamoDB table and stores the data for up to 24 hours.

Developers can use DynamoDB Streams to update and receive item-level data before and after data changes. DynamoDB Streams returns a time-ordered list of data changes made in a table in the previous 24 hours. With a simple API call, you can access a stream and use it to keep other data stores up to date on the latest changes and take actions based on them.

What is DynamoDB Autoscaling and How Does it Work?

One of the most obvious benefits of serverless computing is the hands-off approach that developers can follow when it comes to time- and budget-consuming aspects, such as ensuring that capacity is underused or never limited.  DynamoDB automatically scales up to handle surges in demand without throttling or slow response, and then scales down to avoid wasting resources.

The service accomplishes this through the use of AWS Application Auto Scaling, which allows tables to increase read and write capacity as needed while adhering to your own scaling policy. This policy specifies whether these capacities should be scaled, as well as the minimum and maximum provisioned capacity unit settings. It also includes a target utilisation (the percentage of consumed provisioned throughput), which, together with a target tracking algorithm, ensures that throughput matches as close to the set target as possible regardless of workload.

How is Amazon DynamoDB different from MYSQL?

Amazon DynamoDB is described by developers as a “fully managed NoSQL database service.” For high availability and durability, all data items are stored on Solid State Drives (SSDs) and replicated across three Availability Zones. You can offload the administrative burden of running and scaling a highly available distributed database cluster with DynamoDB, while only paying for what you use. MySQL, on the other hand, is described as “the world’s most popular open source database.” MySQL software provides a high-performance, multi-threaded, multi-user, and robust SQL (Structured Query Language) database server. MySQL Server is designed for mission-critical, high-volume production systems as well as embedding in widely distributed software.

Amazon DynamoDB falls under the “NoSQL Database as a Service” category of the tech stack, whereas MySQL falls under “Databases.”

The primary reason why developers prefer Amazon DynamoDB over competitors is “predictable performance and cost,” whereas “Sql” was mentioned as a key factor in selecting MySQL.

MySQL is a free and open source database with 3.98K GitHub stars and 1.56K GitHub forks.

Is Amazon DynamoDB serverless?

Amazon DynamoDB is a serverless service that scales up and down automatically to adjust capacity and maintain performance. It also has high availability and fault tolerance built in. DynamoDB provides on-demand provisioned and capacity modes to help you save money by specifying capacity per table or paying for only the resources you use. You don’t provision, patch, or maintain any servers.

What You Need?

The database is the foundation of any software development project, regardless of its size. Amazon DynamoDB can handle massive traffic spikes while storing any volume of big data, resulting in excellent performance even when it scales up.
