Let's look at it.

You need to think of DynamoDB data models to understand that. It supports two data models. Key value pairs and wide columns.

Let's look at the first one, key value pair.

  📍 Key value pair is like a massive hash. Hash is a very efficient way of retrieving things. If you know the hash, you can retrieve the value. So you have a table full of hashes and values. you know the hash, you get the value.

  📍 Let's look at wide column now. Wide column is a big hash and instead of having values it has B trees.  B trees are a super performant way of finding things and doing range operations.
