Expand description

Aggregate statistics for DELETE profiling.

§Environment Variables

  • DELETE_PROFILE=1 - Enable timing collection and print summary on thread exit
  • DELETE_PROFILE_VERBOSE=1 - Also print per-delete breakdown to stderr

When DELETE_PROFILE=1 is set, aggregate statistics are automatically printed when the thread-local stats are dropped (typically at thread exit).
