> View is created with {{CREATE VIEW IF NOT EXISTS ... APPEND_ONLY_SCHEMA = 
> true, UPDATE_CACHE_FREQUENCY=900000}} 
> If {{ALTER VIEW <VIEW_NAME> ADD IF NOT EXISTS MYCOL VARCHAR}} is executed 
> before each upsert statement then performance for each 1K batch upsert 
> degrades by ~40X (50ms for 1K batch without alter statement vs 2300ms with 
> alter statement)
> This is for the case when MYCOL exists.
