[GitHub] [rocketmq] Git-Yang opened a new issue #3286: Delay queue supports concurrent delivery of messages

Git-Yang opened a new issue #3286:
URL: https://github.com/apache/rocketmq/issues/3286


   **Problem:**
   The delay queue currently schedules different queue threads through the Timer. Because the timer is a single-threaded scheduling and is executed sequentially and serially, the message delivery performance is poor.

   The test results are as follows:
   - Simultaneously send messages with four delay levels

   **Optimization:**
   - By replacing Timer with ScheduledExecutorService, all queue threads can send messages concurrently.
   The test results are as follows:
   - Simultaneously send messages with four delay levels
