If the CloudWatch metric WriteThrottleEvents for a DynamoDB table is consistently high, what does this indicate?
AThe table is receiving more write requests than its provisioned capacity allows
BThe table has low read traffic
CThe table's latency is very low
DThe table's provisioned capacity is too high
Step-by-Step Solution
Solution:
  1. Step 1: Understand what WriteThrottleEvents measures

    This metric counts write requests denied due to exceeding provisioned write capacity.
  2. Step 2: Interpret a high value

    A high count means many write requests are throttled, indicating demand exceeds capacity.
  3. Final Answer:

    The table is receiving more write requests than its provisioned capacity allows -> Option A
  4. Quick Check:

    High WriteThrottleEvents = Over capacity writes [OK]
Quick Trick: High throttle events mean capacity is too low for demand [OK]
Common Mistakes:
MISTAKES
  • Assuming high throttle means low traffic
  • Confusing read and write metrics
  • Thinking high throttle means low latency
