Describe This Problem

I found hard to debug query performance problem now, following utils I think may be necessary to have:

  • Hot reload for some debugging options
  • Analyze for distributed query

Proposal

  • Slow queries logging file
  • Hot reload for some debugging options
  • Analyze for distributed query
