Excessive use of CPU

Hi all,
    I found kudu has been using CPU 20% or so, but I did not do SQL operation. What are the other built-in operations in kudu ?

Hi Sky,

It's likely that the CPU is going to background operations like compaction.
If you run:
  top -H -p `pgrep kudu-tserver`

it should show you which threads are using the CPU.
