   > Can you outline the benefits of this approach compared to simply running 
perf, etc on the Druid process itself? Is this supposed to mirror: 
https://clickhouse.com/docs/reference/system-tables/trace_log?
   
   It's not similar to the trace_log in clickhouse, but similar to the 
system.stack_trace table in clickhouse.
   This provides an easier and simpler way to dump a stack trace to analyze 
thread usage/potential contention.
   With this SQL support, AI agents can get thread dump to do the analysis for 
us.
