Earlier, there were non-conclusive to me debates / discussions on whether to (always) engage / avoid clustered indexes.
Well, I understood that they are to be used sometimes with proper + specific purposes and context.
"SQL Azure does not support tables without clustered indexes. A table must have a clustered index. If a table is created without a clustered constraint, a clustered index must be created before an insert operation is allowed on the table"
does not fit in the previous conclusions, rationale and explanations.
What is the rationale, that I have missed from prev explanations, of rigidly imposing ubiquity of clustered indexes without any exceptions?
