Currently, I can see only examples using the retention period specified in days. Can we specify the retention period of a table in years in Kusto? I mean will the below command sets the retention period to 10 years? .alter-merge table Table1 policy retention softdelete = 10y recoverability = disabled

Also, soft delete keeps the data in DB and marks the record as deleted right. Is there a way to do hard delete and any issues with using it? My records do not refer to old data and hence I want to completely delete the records after the retention period.

  • The retention policy command receives a timespan literal and year is not one of the supported formats, so the command in your example does not work. You need to specify the period in days.
  • If Recoverability is set to Enabled, the storage artifacts will be deleted from storage 14 days after retention policy expires. If it is set to Disabled deletion will be done 1d after retention policy period.
