PartitionRetentionMode

case class PartitionRetentionMode(retentionCondition: String, description: Option[String] = None) extends HousekeepingMode with SmartDataLakeLogger with Product with Serializable

Keep partitions while retention condition is fulfilled, delete other partitions. Example: cleanup partitions with partition layout dt=<yyyymmdd> after 90 days:

housekeepingMode = {
  type = PartitionRetentionMode
  retentionCondition = "datediff(now(), to_date(elements['dt'], 'yyyyMMdd')) <= 90"
}
retentionCondition

Condition to decide if a partition should be kept. Define a spark sql expression working with the attributes of PartitionExpressionData returning a boolean with value true if the partition should be kept.
