What will happen if a DynamoDB request fails with a throttling error and the retry logic does not include any delay between retries?

medium🧠 Conceptual Q5 of 15
DynamoDB - with AWS SDK
What will happen if a DynamoDB request fails with a throttling error and the retry logic does not include any delay between retries?
AThe client SDK will automatically add delays
BThe retries will succeed immediately without delay
CThe retries will likely fail immediately, causing a fast failure loop
DThe request will be queued automatically by DynamoDB
Step-by-Step Solution
Solution:
  1. Step 1: Understand throttling error behavior

    Throttling means request rate is too high; retrying immediately repeats the problem.
  2. Step 2: Effect of no delay in retries

    Retries without delay cause rapid repeated failures, not success.
  3. Final Answer:

    The retries will likely fail immediately, causing a fast failure loop -> Option C
  4. Quick Check:

    No delay retries = fast failure loop [OK]
Quick Trick: Always add delay between retries to avoid fast failure loops [OK]
Common Mistakes:
MISTAKES
  • Assuming retries succeed instantly without delay
  • Believing DynamoDB queues requests automatically
  • Thinking SDK adds delay without explicit code
