What is the purpose of below configuration in cron group xml file? I did not fully understand the meaning of those lines:
schedule_generate_every
Frequency (in minutes) that schedules are written to the cron_schedule table.
schedule_ahead_for
Time (in minutes) in advance that schedules are written to the cron_schedule table.
schedule_lifetime
Window of time (in minutes) that cron job must start or will be considered missed (“too late” to run).
Thanks
schedule_generate_every: How often would you like your job to run? Every minute, every 5 minutes, every hour, every day...
schedule_ahead_for: How far in advance would you like to schedule jobs? Example: cron runs at 1pm. schedule_ahead_for is set to 1 hour. Cron jobs for the next hour are scheduled.
schedule_lifetime: In the event that the job's scheduled time passes without the job running, should Magento skip the job? If the schedule_lifetime is zero, yes, Magento skips it. If this value is 5 minutes and the job is expired by only 4 minutes, then Magento will run the job.
