Question

How does partial cracking manage storage space for cracking columns?

a.

It materializes all possible values in cracking columns.

b.

It uses a strict LRU policy to manage columns.

c.

It allows each small physical column to be thrown away and recreated based on access patterns.

d.

It allocates a fixed amount of storage space for each cracking column.

Answer: (c).It allows each small physical column to be thrown away and recreated based on access patterns. Explanation:Partial cracking manages storage space for cracking columns by allowing each small physical column to be thrown away and recreated based on access patterns, and it uses an LRU policy to decide when to do so.
