For partitioned schedules, controls the maximum number of past partitions for each schedule that will be considered when looking for missing runs . Generally this parameter will only come into play if the scheduler falls behind or launches after experiencing downtime. This parameter will not be checked for schedules without partition sets (for example, schedules created using the @schedule decorator) - only the most recent execution time will be considered for those schedules.
Note that no matter what this value is, the scheduler will never launch a run from a time before the schedule was turned on (even if the start_date on the schedule is earlier) - if you want to launch runs for earlier partitions, launch a backfill.
Default Value: 5
For each schedule tick that raises an error, how many times to retry that tick
Default Value: 0
