Advanced configuration option. Specifies a number of days between 0 and the
value of `model_snapshot_retention_days`. After this period of time, only the first
model snapshot per day is retained for this job. Age is calculated relative to
the timestamp of the newest model snapshot. For new jobs, the default value is
`1`, which means that all snapshots are retained for one day. Older snapshots
are thinned out such that only one per day is retained. For jobs that were
created before this setting was available, the default value matches the
`model_snapshot_retention_days` value, which preserves the original behavior
and no thinning out of model snapshots occurs.
Advanced configuration option, which affects the automatic removal of old model
snapshots for this job. It specifies a period of time (in days) after which only
the first snapshot per day is retained. This period is relative to the timestamp
of the most recent snapshot for this job. Valid values range from `0` to
`model_snapshot_retention_days`. For new jobs, the default value is `1`. For
jobs created before version 7.8.0, the default value matches
`model_snapshot_retention_days`. For more information, refer to
{ml-docs}/ml-model-snapshots.html[Model snapshots].

ten days older than the newest snapshot are deleted. For more information, refer
