Dynamodb Amazon – In this challenge, Amazon S3 meets DynamoDB and we see how we can connect AWS services to access and query data without writing a single line of code!

Currently, we want to use the analytics platform to read and write information using an Amazon S3 object storage service, and then directly access the data to create, populate, and interact with Amazon DynamoDB, a key-value database, and a NoSQL document. it is one of the few tools with a graphical user interface that allows you to connect to DynamoDB tables without writing any code. All we need is the Amazon S3 Connector (Labs) and the Amazon Dynamo DB Nodes extension and an Amazon account with the appropriate credentials.

Create A Dynamodb Table

In our example, we’ll show you how to authenticate against the Amazon service, access data with S3, and then create and load a DynamoDB table. We’ll also show some utility nodes that query DynamoDB, list and describe available tables, and provide batch operations if needed.

Figure 2. Workflow to access data via S3, load data into DynamoDB table and perform various ETL operations on the table.

Since most points in this workflow require access to an Amazon account in some way, let’s start with the Amazon authentication point. Here, we provide the Access Key ID and Secret Key, and we also choose to use the Change Role option, which requires us to provide the existing account and role as well, giving us additional permissions. After selecting the appropriate field, we can click on the Test Connection button to make sure that all the information provided is correct.

Note that the blue square connection port provided by this node – the Amazon connection information it contains – will be distributed to other Amazon nodes, so we only need to provide the login information once.

Now, let’s connect to S3 and upload some data that will be transferred to an Amazon DynamoDB table. In this case, we will use the popular adult dataset provided by the UCI machine learning repository. The data set is based on the US. It contains census data and information about people, such as gender, marital status, location, etc. To begin, we will use the Amazon S3 Connector node. This point will take the login credentials we provided and give us access to the S3 bucket where we can write the data – the path to the working directory is what we need to provide. The output port for this point is Til, which represents the Amazon S3 connection.

We access the adult.xlsx file in S3 using the file management function introduced in 4.1 with the Excel Reader node. An Excel Reader node can directly access Excel files available on S3 on its optional input port if an Amazon S3 connection is provided. This feature is activated by clicking on the 3 dots in the lower left corner of the node. (Figure 4.)

After reading the data directly from S3, we can now focus on moving the data into DynamoDB for further exploration and manipulation.

The next thing we want to do is create an empty DynamoDB table. To do this, we need to define the name of the table and the primary key that identifies each element of the table. There are two main types of primary keys in DynamoDB: simple and composite.

We can create a table using the Amazon DynamoDB Create Table node. In its configuration, we are given several options to choose the name of the table, to determine the hash according to the string keys (and according to the corresponding types), to choose the billing mode and to set the read and write units. Here we will choose the hash key

(single), be careful about matching cases to fields in our S3 table. For other options, we will keep the default value. Note that we also have the option to add indexes and labels for our tables in a separate tab if desired.

Now that the table is ready, we can use the Amazon DynamoDB Batch Put node to load data from S3 into it. Configuration allows you to browse the existing DynamoDB tables in your account and select the appropriate batch size.

Now that our data is loaded, there are several nodes available in the Amazon DynamoDB extension for searching, browsing, and other utility functions:

Finally, after some queries on my table, I might want to read the current state of the DynamoDB table back to the original table form for additional processing, or simply remove the DynamoDB table when it’s done. It is possible with this point:

In the end it’s my choice – I can use S3 or local data to load into DynamoDB. Once there, I have many options to directly query and manipulate my dataset in DynamoDB without writing any code. And finally, I always have the option to bring my data back for further processing, model development, visualization or expansion.

Today let’s leave the earth and go to the clouds! When we talk about the cloud, two options immediately come to mind: the Amazon cloud and the MS Azure cloud. Both clouds offer proprietary bulk storage (data lakes) for data storage: Amazon’s cloud uses S3 data storage and MS Azure has uploaded Blob storage data storage.

Organizations are increasingly using cloud services to achieve high levels of scalability, security and performance. In recent years, Amazon Web Services (A … You sign in with a different tab or window. Reload to refresh your session.
