Meter archive files must be processed in parallel across the cluster. What foundational distributed-computing practice enables that parallelism?
Select an answer to reveal the explanation.
Short Explanation
Parallel jobs need the data already sliced across machines. Think many mail carriers each taking a street instead of one carrier walking the whole city.
Full Explanation
Distributed processing depends on partitioning data so workers operate on subsets concurrently. In Hadoop-style systems, large files are split into blocks placed across nodes, enabling parallel map tasks. Leaving multi-terabyte archives as a single unsplittable unit negates cluster parallelism regardless of how many CPU cores exist elsewhere.
