How to filter the data being copied?

[rafcremer]

Hi, is there a way to filter the data that is being copied so I can choose to not copy the records I don't need based on some condition?

Let's say I want to only copy records from one table to another where the CustomerID is the one I specify instead of coping all records.
If I try to do that in the transform function, I get a MultipleValidationErrors error.

It would be helpful if I could define filter expressions to be used with options.source.dynamoClient.scan in your scan method.

A workaround I came up with is to return null in the transform function for the items you don't want copied. Then go to your node_modules/copy-dynamodb-table/index.js file and add this line of code to the mapItems functions:

data.Items = data.Items.filter(item => item?.PutRequest?.Item);
