Database Administration Interview Question:

Explain What is index cluster?

Submitted by: Administrator

An index cluster uses an index to maintain data within the cluster. The structure of a cluster index is similar to a normal index.
Although a normal index does not store NULL key values, and index cluster can store it.
And, a cluster index is likely to be smaller than a normal index because, there is only one entry for each key value in the cluster index, even if that is repeating.
