Error: DynamoDB batch write is not working

Answered by Rafal Wilinski
What's Causing This Error
The error DynamoDB batch write not working can be caused by a variety of issues, such as:
- Improperly formatted requests.
- Insufficient provisioned write capacity on the table.
- Concurrent requests exceed the provisioned write capacity of the table.
- Issues with the IAM role associated with the request.
- Errors with the batch write a function or the SDK being used.
- Maximum batched requests exceeded. Currently DynamoDB only allows batchWrites up to 25 items per invocation
Solution: Here's How To Resolve It
To solve this error, you can take the following steps:
- Double-check the format of the requests sent to the DynamoDB service to ensure they are properly formatted.
- Check the provisioned write capacity on the table and increase it if necessary.
- Consider implementing exponential backoff to handle retries for failed requests.
- Check the IAM role associated with the request to ensure it has the necessary permissions to write to the table.
- Verify that the
batchwrite
function or SDK is configured correctly, and all necessary dependencies are installed. - Try to use the
batch_write_item()
function provided by the AWS SDK for Python (Boto3) to write the items in the table. - If the issue persists, you may contact AWS support for further assistance.
- You can also check the
CloudWatch
metrics for the DynamoDB table to see if you exceed the write capacity units.
