A company has used an Amazon Redshift table that is named Orders for 6 months. The company performs weekly updates and deletes on the table. The table has an interleaved sort key on a column that…

VACUUM FULL performs a full vacuum operation, which reclaims disk space by physically removing deleted rows and also re-sorts the table, which is essential for maintaining the effectiveness of an interleaved sort key after frequent updates and deletes. The re-sorting implicitly reanalyzes the sort key column to ensure query performance.

VACUUM DELETE ONLY only reclaims space from deleted rows without re-sorting the table, which would not address the need to maintain the interleaved sort key's effectiveness.

VACUUM REINDEX is not a standard or recognized Redshift VACUUM option for a full re-sort or re-analysis; Redshift's VACUUM command handles sorting and analyzing as part of FULL or SORT ONLY operations.

VACUUM SORT ONLY re-sorts the table but does not reclaim disk space from deleted rows, so it would not meet the requirement to prevent running out of storage space.
