Azure file deletion not working with life cycle management rule

Pothineni, A 6

Hi, We have a requirement to delete the files after certain days from storage container folders.

I have set a rule to delete them as per below. But looks like this rule is not getting triggered. Please advice.

{
"rules": [
{
"enabled": true,
"name": "test",
"type": "Lifecycle",
"definition": {
"actions": {
"baseBlob": {
"delete": {
"daysAfterModificationGreaterThan": 1
}
}
},
"filters": {
"blobTypes": [
"blockBlob"
],
"prefixMatch": [
"raw / BV/ landing / BV-data-to-Data-Lake-Integration/events",
"raw / BV/ landing / BV-data-to-Data-Lake-Integration/event_",
"raw / BV/ landing / BV-data-to-Data-Lake-Integration/sensors"
]
}
}
}
]
}

Hi, @Pothineni, A

Triggered once a day. Has 24 hours passed since the setting? (up to 48 hours if modifying an existing policy)

The prefix seems to contain a space.Is this policy correct?

Hi @Takahito Iwasa , Thanks for getting back to me. Good pick up. I just fixed the spaces between folders.

Yes its been more than a day since policy was created but now that I have fixed the filters will it take another 48 hours to kick in ?

@Pothineni, A

Sounds good.
Yes, the following documentation says it can take up to 48 hours.

The updated policy takes up to 24 hours to go into effect. Once the policy is in effect, it could take up to 24 hours for the actions to run. Therefore, the policy actions may take up to 48 hours to complete.

makes sense but policy is few days old now since it was first created.

I am suspecting the spaces between the folder path is why it didnt work ?

also, In the folders above the file names are usually appended with timestamp at the end. So when I said event_ or events or sensors the rule, it should be checking for list of files stating with the name as listed is it ?
