Implement a custom solution that bypasses Delta Lake's transaction log to directly modify data files, aiming to reduce logging overhead and improve performance.

Utilize Delta Lake's transaction log exclusively for tracking changes, performing updates and deletions as separate transactions to ensure data consistency.

Employ Delta Lake's upsert capability to efficiently update or insert data based on a unique key, leveraging the transaction log for consistency without significant performance overhead.

Apply Delta Lake's delete feature in isolation to remove data based on specific conditions, relying on the transaction log for audit trails.
