- 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.
