schedulinglogging: some cluster setting values cause CPU usage to increase to 100% #87771
Description
Describe the problem
If I set the following cluster settings:
set cluster setting "sql.telemetry.capture_index_usage_stats.interval" = '0s';
set cluster setting "sql.telemetry.capture_index_usage_stats.check_enabled_interval" = '0s';
set cluster setting "sql.telemetry.capture_index_usage_stats.logging_delay" = '0s';
Then the task "capture-index-usage-stats" starts to busy-loop with a zero timer.
Expected behavior
There should be a minimum delay between iterations to avoid a busy loop.
