Parquet Over Raw Formats
parquet-over-raw-formats · always_apply: yes
Content
Transform raw JSON/CSV into Apache Parquet before it's queried at scale. AWS's benchmark: ~87% space savings, ~34x faster Athena queries, ~99.7% lower query cost versus CSV on the same 1 TB of log data. Raw format is fine for the landing zone; Parquet is required for anything queried repeatedly.
