Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the number of shards in the stream.
Increasing the number of shards increases the write capacity, directly addressing the throughput exceeded error. Option B is wrong because the error is not from the producer side. Option C is wrong because the error is about write throughput, not read. Option D is wrong because the error is not about data format.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Increase the number of shards in the stream.
Why this is correct
More shards provide higher write throughput.
- ✗
Modify the producer to use a different partition key.
Why it's wrong here
Partition key affects distribution but not total throughput.
- ✗
Compress the data before sending to the stream.
Why it's wrong here
Compression reduces data size but does not increase throughput capacity.
- ✗
Enable enhanced fan-out for consumers.
Why it's wrong here
Enhanced fan-out improves read throughput, not write.
