Which statement correctly addresses concerns regarding Delta Lake's time travel functionality in relation to deleted data access?

The statement that deleted records may be accessible with time travel for around 24 hours is correct because Delta Lake's time travel functionality allows users to access historical versions of their data. When a record is deleted, it can still be accessed by reverting to an earlier version of the Delta table before the deletion occurred. The time travel feature leverages Delta Lake’s underlying storage mechanism, which retains historical versions to facilitate data recovery, auditing, and debugging.

In practice, after a deletion, the prior versions of the data (which include the deleted records) remain accessible for a predefined retention period. This period can vary based on the configurations set for the Delta Lake table, but typically, Delta Lake retains this historical data, allowing access to it through time travel for a certain amount of time.

This addresses the concern regarding how deleted records can still be accessed, as long as you refer to the state of the table prior to the deletion within the specified retention timeframe. This functionality helps in scenarios where accidental deletions occur or when historical analyses are needed on previous states of the dataset. The retention of this data for a period provides a safeguard rather than an immediate removal, which would limit the ability to recover important data.
