Question

What is the purpose of partial cracking in column-store systems?

a.

To create complete columns for all data values

b.

To minimize the storage overhead of column pairs

c.

To perform updates on cracking columns

d.

To materialize all possible cracking data

Posted under Big Data Computing

Answer: (b).To minimize the storage overhead of column pairs Explanation:The purpose of partial cracking in column-store systems is to minimize the storage overhead of column pairs by materializing only the values needed by the current hot workload set in cracking columns.
