[SQL] More aggressive defaults
- Turns on compression for in-memory cached data by default
- Changes the default parquet compression format back to gzip (we have seen more OOMs with production workloads due to the way Snappy allocates memory)
- Ups the batch size to 10,000 rows
- Increases the broadcast threshold to 10mb.
- Uses our parquet implementation instead of the hive one by default.
- Cache parquet metadata by default.
