What’s Amazon DynamoDB?

DynamoDB (AWS Amazon Web Services)is one of the most recent presented by Amazon, aws dynamoDB published on January 18, 2012, it is a fully managed and customization NoSQL database service that provides fast and predictable performance along with excellent services.

The DynamoDB Environment only exist of using your AWS account to access the DynamoDB GUI console, however, you can also using a local install.

The simple, guided process will inform you of all the related fees and requirements.

After performing all the necessary steps of the process, you will have the access. Simply sign in to the AWS console, and then navigate to the AWS DynamoDB console.

Let’s quickly analyze its positive and negative aspects in the lists below:

AWS DynamoDB Advantages

The two main advantages of DynamoDB are scalability and flexibility.

Its design their self also supports a wide range of use from lighter tasks and operations to demanding enterprise functionality. It additionally permits basic and simple use of multi languages: Ruby, Java, Python, C#, Erlang, PHP, and Perl.

AWS DynamoDB Limitations

DynamoDB suffers from specific constraints; be that as it may, these restrictions don't really make immense issues or block strong improvement.

You can review them from the following points

Capacity Unit Sizes − A read capacity unit is a single consistent read per second for items no larger than 4KB. A write capacity unit is a single write per second for items no bigger than 1KB.

Provisioned Throughput Min/Max − All tables and global secondary indicates have a minimum of one read and one write capacity unit. Maximums depend on region. In the US, 40K read and write remains the cap per table (80K per account), and other regions have a cap of 10K per table with a 20K account cap.

Provisioned Throughput Increase and Decrease − You can increase this as often as needed, but decreases remain limited to no more than four times daily per table.

Table Size and Quantity Per Account − Table sizes have no limits, but accounts have a 256 table limit unless you request a higher cap.

Secondary Indexes Per Table − Five local and five global are permitted.

Projected Secondary Index Attributes Per Table − DynamoDB allows 20 attributes.

Partition Key Length and Values − Their minimum length sits at 1 byte, and maximum at 2048 bytes, however, DynamoDB places no limit on values.

Sort Key Length and Values − Its minimum length stands at 1 byte, and maximum at 1024 bytes, with no limit for values unless its table uses a local secondary index.

Table and Secondary Index Names − Names must conform to a minimum of 3 characters in length, and a maximum of 255. They use the following characters: AZ, a-z, 0-9, “_”, “-”, and “.”.

Attribute Names − One character remains the minimum, and 64KB the maximum, with exceptions for keys and certain attributes.

Reserved Words − DynamoDB does not prevent the use of reserved words as names.

Expression Length − Expression strings have a 4KB limit. Attribute expressions have a 255-byte limit. Substitution variables of an expression have a 2MB limit.

Aapthi Tech Hyderabad specialized to handle DynamoDB projects, we worked with Dynamodb and PHP for couple of years with our client projects.

Deploy and Test Locally - Amazon DynamoDB

What Aapthi Technologies is thinking that maintain good database of dynamodb development, we are promoting Single Page Application might be people are using Hybrid application development providers. We are take care of SPA development in India, dynamodb development, this is the best offer for small and big companies by using virtual servers, we dont buy any server for manually.
