Colocation (same distribution) The file-level co-distribution enables fast access to files and avoids a large amount of network overhead caused by data relocation.

Question

Options

• ATrue
• BFalse

• A
  78% (31)
• B
  23% (9)

Explanation

Option A is correct because file-level co-distribution (colocation) places related files on the same node or partition, meaning reads and joins can happen locally without shuffling data across the network - this is a foundational optimization in distributed systems like HDFS, Spark, and distributed databases.

Option B is wrong because it contradicts how colocation works by design: the entire purpose of co-distributing files is to eliminate inter-node data movement, not introduce it.

Memory tip: Think of colocation like keeping all your cooking ingredients in one kitchen cabinet - you don't have to run to different rooms (nodes) to grab what you need, so you cook (process) faster with far less effort (network overhead).
