URL: https://github.com/apache/bookkeeper/issues/2878


   **QUESTION**
   
   In our usage scenario, in the case of high-throughput writes, we found that 
the cpu utilization of rokskdb:low:XX thread can easily reach 100%. Are there 
any good suggestions for optimizing the rocksdb parameters in this situation?
   
   As you can see from the screenshot:

   We have tried turning off the compression, but nothing seems to have changed.
   ```
   dbStorage_rocksDB_lz4CompressionEnabled=false
   ```
   
   Any suggestions would be greatly appreciated~
