Question

What is the primary benefit of NoDB's selective parsing approach when dealing with queries that involve multiple filtering conditions?

a.

It performs parsing and tokenizing for all attributes in each row.

b.

It abandons rows as soon as any filtering predicate fails, avoiding significant parsing costs.

c.

It fully loads all data before parsing, reducing overhead.

d.

It applies all filtering predicates sequentially, increasing parsing efficiency.

Answer: (b).It abandons rows as soon as any filtering predicate fails, avoiding significant parsing costs. Explanation:The primary benefit of NoDB's selective parsing approach is that it abandons rows as soon as any filtering predicate fails, thereby avoiding significant parsing costs for rows that do not meet the filtering conditions.
