Reynold Xin 2f0b882e5c [SPARK-14482][SQL] Change default Parquet codec from gzip to snappy ... ## What changes were proposed in this pull request? Based on our tests, gzip decompression is very slow (< 100MB/s), making queries decompression bound. Snappy can decompress at ~ 500MB/s on a single core. This patch changes the default compression codec for Parquet output from gzip to snappy, and also introduces a ParquetOptions class to be more consistent with other data sources (e.g. CSV, JSON). ## How was this patch tested? Should be covered by existing unit tests. Author: Reynold Xin <rxin@databricks.com> Closes #12256 from rxin/SPARK-14482.		2016-04-08 23:52:04 -07:00
