> @bigcyy Is my understanding correct? Could you take a look?
Thank you for clarifying. I just want to summarize my understanding of the
proposed improvements to make sure I'm on the same page.
As I understand it, the two main suggestions are:
1. Replace RPOP with BRPOP: The goal here is to avoid the consumer thread
from busy-waiting or spinning in a tight loop when the queue is empty. Using
the blocking BRPOP (with an appropriate timeout) is much more efficient and
prevents unnecessary CPU waste.
2. Implement Exponential Backoff for Exceptions: When the consumer
encounters an unexpected exception (such as a network error or a connection
failure, rather than just an empty queue), the thread should not terminate.
Instead, it should implement an exponential backoff strategy for retrying the
connection/operation. This makes the consumer more resilient and prevents it
from either crashing or overwhelming the system with rapid retries during a
failure.
Is my understanding of your proposed solutions correct?
