How to test and confirm botocore retry config for DynamoDB?

[pinarkaymaz6]

For our DynamoDB implementation in a Lambda, I created a retry configuration as seen below. I pass different values to the configuration parameter max_attempts to override the default retry max attempts. However, I cannot confirm the new retry quota. I enabled DEBUG logs for botocore and boto3 and it does not say much. How can I test and confirm that max attempt value is actually overriden by the new value?

Here is the code snippet for the dynamodb with retry config:

import os
import boto3
from botocore import config

RETRY_CONFIG = config.Config(
   retries = {
      'max_attempts': 7,
      'mode': 'standard'
   }
)

db = boto3.resource('dynamodb', config=RETRY_CONFIG)
table = db.Table(table_name)

Here are the DEBUG logs from botocore for a table query:

[DEBUG]	2023-11-14T15:40:58.488Z	61af46da-1028-4fe4-ab98-45fc42574f91	Event after-call.dynamodb.Query: calling handler <bound method RetryQuotaChecker.release_retry_quota of <botocore.retries.standard.RetryQuotaChecker object at 0x7f48574d6850>>

[DEBUG]	2023-11-14T15:40:58.412Z	61af46da-1028-4fe4-ab98-45fc42574f91	Not retrying request.

Okay I finally figure out how to confirm max attempts. Logging the client meta like this prints the total_max_attempts which is max_attempts + 1:

logger.debug(f"DynamoDB retry config: {db.meta.client.meta._client_config.retries}")

It prints:

[DEBUG] 2023-11-15T14:08:28.375Z DynamoDB retry config: {'mode': 'standard', 'total_max_attempts': 8}
