Amazon Simple Queue Service (SQS) is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. It allows you to send, store, and receive messages between software components at any volume, without losing messages or requiring other services to be available.
When working with AWS SQS, you might encounter the error code AWS.SimpleQueueService.TooManyEntriesInBatchRequest. This error typically arises when you attempt to send a batch request that contains more entries than the service allows.
Developers often see this error when they try to send a batch of messages to an SQS queue and the batch size exceeds the permitted limit. The error message is clear: the batch request contains too many entries.
The error code AWS.SimpleQueueService.TooManyEntriesInBatchRequest indicates that the batch request you are trying to process contains more than the allowed number of entries. AWS SQS has a limit of 10 entries per batch request. This limit is in place to ensure efficient processing and to maintain the performance of the service.
This issue usually occurs when developers are unaware of the batch size limit or when there is a miscalculation in the logic that constructs the batch request.
To resolve this issue, you need to ensure that your batch requests do not exceed the maximum limit of 10 entries. Here are the steps you can follow:
Examine the part of your code that constructs the batch request. Ensure that the logic correctly calculates the number of entries and does not exceed 10. You might need to implement a loop or a batching mechanism to split larger sets of messages into multiple batches.
Adjust your code to handle message batching appropriately. Here is a simple example in Python using the Boto3 library:
import boto3
sqs = boto3.client('sqs')
queue_url = 'YOUR_QUEUE_URL'
messages = [{'Id': str(i), 'MessageBody': 'Message {}'.format(i)} for i in range(15)]
# Split messages into batches of 10
for i in range(0, len(messages), 10):
batch = messages[i:i + 10]
response = sqs.send_message_batch(
QueueUrl=queue_url,
Entries=batch
)
print(response)
After modifying your code, test it to ensure that the batch requests are processed without errors. Monitor the logs to confirm that the error AWS.SimpleQueueService.TooManyEntriesInBatchRequest no longer appears.
