batch.size and buffer.memory settings to avoid producer blocking under high load?How can you combine batch.size and buffer.memory settings to avoid producer blocking under high load?
hard📝 Application Q9 of 15
Step-by-Step Solution
Solution:
Step 1: Understand buffer.memory and batch.size relation
buffer.memory is total memory for all batches; batch.size is size per batch. To avoid blocking, buffer.memory must accommodate multiple batches.Step 2: Correct sizing to prevent blocking
Setting buffer.memory much larger than batch.size times concurrent batches ensures enough memory to buffer messages without blocking.Final Answer:
Set buffer.memory much larger than batch.size times number of concurrent batches -> Option DQuick Check:
buffer.memory > batch.size * concurrency prevents blocking [OK]
Quick Trick: buffer.memory must cover multiple batches to avoid blocking [OK]
Common Mistakes:
MISTAKES- Setting buffer.memory too small causes blocking
- Matching buffer.memory to batch.size causes memory shortage
- Setting buffer.memory to zero disables buffering incorrectly
