- The page reports a 2.94-second full-file load in a 15 GB synthetic CSV test; it explicitly says the mock data is not a performance benchmark.
Field notes
The described workflow starts from a file, shard folder, or database table, then narrows fields and queries before showing paged results. RowCove says edits preserve source context and are saved as a separate copy. The page reports 2.94 seconds for a 15 GB mock CSV, but labels its examples synthetic and says they are not a performance benchmark; Pro plans are still marked as coming soon.
