xyxiaoyou commented on issue #17186: [SPARK-19846][SQL] Add a flag to disable constraint propagation URL: https://github.com/apache/spark/pull/17186#issuecomment-560330324 Hi, @gatorsmile , when using 'create or replace view test_view as...', spark will first generate a 'select...'query job. This causes the create view to be particularly slow. Is there a switch control so that spark does not do queries or create faster when creating a view?
