I am using the import from s3 option to import a csv to a DynamoDB tables. This has worked fine before but for this particular csv of 500 items, AWS is only importing 100 of them. It seems like DynamoDB is importing the first 50 and last 50 items in the csv and ignoring the rest.

Is there any configuration I am missing?

Status page shows that 500 items where successfully imported with 0 errors.

However, When I do a live item count scan, DynamoDB only reports back 100 items in the table.

CloudWatch only produced an info log stream and no error log streams.
