I have a DynamoDB table with a model that contains and itemData property of type Map that contains count and limit properties.

I am interested in using dynamodb for modelling my data for performance. I want to create a database of meeting events. This is an example diagram of data I have modelled based upon what I think dynamodb can do.

I’m running a scan on a table and it comes across the same PK multiple times. As advertised, it’s not very efficient.

My DynamoDb table has 3000 rcu and 1000 wcu, the data size is well below 10 GB. Based on the formula to calculate partitions, 2 partitions will be created. I don’t understand why 2 partitions are created but not one ?? Since the required rcu and wcu can be handled by one partition. Please anyone explain.

I have the need to store temporarily some change tracking data in DynamoDB.

I’m building an web application, which uses DynamoDB as its database. I understand by default DynamoDB is eventual consistency. My application is set up such that the user is only interested in their data, that means a user won’t depend on other dynamic data, but their own.
Let’s say a user reads(GET) their name=hello. They change(POST) it to name=world.
Can the subsequent GET be guaranteed to be name=world? I’m talking about the case where the user sits in front of one machine at a one geographical location.

I am trying to update an entry in my DynamoDB Table via this piece of code below :
