Error: DynamoDB failedbatch retry

What's Causing This Error

There are several instances that may cause a retry of batch operation to fail again and again In DynamoDB. For example, this may occur because you retry to process the unprocessed items repeatedly without a timeout. Another instance is that the table's throughput is insufficient to handle the batch operation.

Solution: Here's How To Resolve It

To eliminate the above causes, first of all, check and increase the throughput for the DynamoDB table so that the provisioned throughput is not exceeded when handling the batch operation. Otherwise, the batch operation will fail and result in this error. Another way to resolve this issue is to use a proper back-off strategy when you retry unprocessed operations. That will prevent the service from being overwhelmed with too many retry attempts over a short time period.
