ORC support?
- fs111 10y agowhat for if you have parquet? orc feels like a "me too" technology from Horton
- buremba 10y agoWe have 300tb of orc data and can't convert it to Parquet. Also, ORC performs better for our use-case.
- hcoyote 10y agoWhat, specifically, is preventing the conversion? I've converted hundreds of TBytes to Parquet (including moving away from that HIVE ACID stuff).
- buremba 10y agoMainly the development cost. We trust OCR and have good experience with it, it's stable, fast and compact. We don't have any experience with Parquet and it's just too hard/risky to make this kind of conversion on a production system.
- idunno246 10y agoparquet is much less well supported by presto. Facebook is ORC, so ORC gets implemented and optimized first
- jeffbarr 10y agoWe plan to add additional formats over time. I know that ORC is on the list.
