DynamoDB Set order

Question

From DynamoDB docs:

An attribute of type String Set. For example:

"SS": ["Giraffe", "Hippo" ,"Zebra"]

Type: Array of strings

Required: No

This is all I could find. I did some testing but that's clearly not enough for production environments and I would like to get a confirmation/confutation from people who have actually worked with these Sets.

Do DynamoDB Sets maintain insertion order? Can I count on that fact & build logic around that?

Im mainly interested in String Set but it probably applies to all of them (String, Number, Binary).

Answer 1

Here is the documentation. SET data type doesn't preserve the order.

SET : The order of the values within a set are not preserved; therefore, your applications must not rely on any particular order of elements within the set.

LIST - A list type attribute can store an ordered collection of values
