Semi-structured JSON 311 payloads and free-text inspector logs need a landing zone before schema-on-read jobs. How does HDFS support that Variety need?
Select an answer to reveal the explanation.
Short Explanation
A loading dock can take crates of many shapes before anyone unpacks them. HDFS plays that dock for Variety: JSON and text logs can land first; schema-on-read jobs sort meaning later. Demanding one OLTP schema at the curb blocks the Variety story.
Full Explanation
HDFS can store heterogeneous file types without forcing a single relational schema at ingest. That flexibility supports Big Data Variety: JSON, logs, and other forms land first, and later tools apply schema-on-read. Requiring rigid OLTP schemas or rejecting non-image types at the store layer undermines that landing-zone role.
