how to simulate batchWriteItem to fail to get UnprocessedItems

[ersoy-insider]

Hello all;

I want to simulate a failure case for BatchWriteItem to get UnprocessedItems and retry again.

I set write capacity unit to 1 and dispatched multiple asynchronous jobs to process multiple batchWriteItem requests in paralel but all i get is ProvisionedThroughputExceededException and it doesn't contain any UnprocessedItems.

I checked both API Reference for BatchWriteItem and SDK but couldn't find an answer. Additionally tried this stackoverflow answer but it doesn't work as expected.

It would be great, if someone provide a guide to simulate a failure case for BatchWriteItem.
