Based on the test results, the following conclusions are drawn (for reference only):

  • When the batch.size of production requests is 16 times larger, the message production rate increases, and the CPU usage decreases.
  • Compared with cross-AZ production, intra-AZ production significantly increases message production rate and CPU usage.
  • When the number of replicas changes from 1 to 3, the message production rate decreases significantly, and the CPU usage increases.
  • Compared with synchronous replication, asynchronous replication increases the message production rate and the CPU usage.
