That's all from one execution of the existing {{{}CancelCompactionsTest{}}}.
It demonstrates how this logging improves identifying tables and running
compactions involved, and who/why pausing it.
bq. debugToInterruptFor is just to optionally add view/index names to log
message right? so it would print … in a table without 2is/Mvs and … with mvs ?
correct
I'm ok without the test around onelinerStackTrace.
[~paulo], are you ok if I merge this now ?
