Analytics jobs write temporary output and then rename large directory trees to commit results. They need path ACLs. Which storage option is appropriate?

Choose the single best answer.

A.Azure Table storage because RowKey is a filesystem path
B.Flat Blob namespace solely because slashes give identical atomic directory semantics
C.ADLS with hierarchical namespace, after checking feature compatibility
D.Managed disks on disposable workers as the only persistent lake

Show the answer and explanation

✓ Correct answer

ADLS with hierarchical namespace, after checking feature compatibility

HNS supplies real directories and path ACLs suited to analytics. Slashes in flat object names are not equivalent. Table keys are not a directory API; worker disks alone are not a resilient shared analytics lake. Source guide: PDF page 27.
