<AccordionGroup>
  <Accordion title="Who can create deletion rules?">
    Deletion rules are available only to users with the **CDP Admin** role.
  </Accordion>

  <Accordion title="How long does the deletion process take?">
    The deletion process can take from **1 hour to 10 days**, depending on data volume and pipeline sequence.
  </Accordion>

  <Accordion title="Can I delete all types of data from a specific source?">
    If a specific source is selected, only event data will be deleted. To delete all types of data, including identifiers, profile attributes, and more, **All Sources** must be selected.
  </Accordion>

  <Accordion title="What happens if I archive a deletion rule?">
    Archiving a deletion rule will stop its execution once the current iteration completes. If the rule is in progress, it will finish before being archived.
  </Accordion>

  <Accordion title="Can I reuse an archived deletion rule?">
    No, you cannot reuse an archived deletion rule.
  </Accordion>

  <Accordion title="Can I modify the frequency or selected source after creating a deletion rule?">
    You can only modify the frequency for a recurring rule and not for one-time deletion rules.
  </Accordion>

  <Accordion title="Can I pause and resume a deletion rule?">
    You can pause an active deletion rule. If the rule is in progress, it will complete the current iteration before pausing. For recurring rules, it pauses before the next iteration. You can also resume a paused rule.
  </Accordion>

  <Accordion title="What happens if I select 'All Sources'?">
    Selecting **All Sources** allows you to delete all attribute types, including event data, identifiers, profile traits, consent data, and marketing preferences.
  </Accordion>

  <Accordion title="What are advanced filters, and how do they affect record deletion?">
    Advanced filters allow you to set conditions for more precise deletion. For example, if 1,000 records qualify for deletion, you can filter to delete only those with specific attributes, reducing the number of records deleted.
  </Accordion>

  <Accordion title="Is the deletion process reversible?">
    No, the deletion process is irreversible. Ensure all necessary precautions are taken before triggering the deletion rule.
  </Accordion>

  <Accordion title="Can deleted records be recovered?">
    Once records are deleted, they cannot be recovered. Although UCIDs affected by the deletion are stored, the actual deleted data cannot be restored.
  </Accordion>

  <Accordion title="How does the event timestamp relate to profile attributes?">
    When using the event timestamp, the system queries the event table first and then joins the qualified users with other tables for attribute deletion, provided those attributes were ingested by the selected source.
  </Accordion>
