> Yes, simply dropping stats other than truncating stats is less error-prone. This in turn will drop column index of that column. I agree, truncating UTF-8 encoded strings is a pain (I know, I've done it). But the default cutoff for statistics is 4KB. That can lead to some pretty big footers when you have hundreds or thousands of pages. For comparison, parquet-mr uses a default of 64 bytes as a max for the column index statistics. I'm not saying truncation has to be part of this PR, just that it should be considered in the future. -- This is an automated message from the Apache Git Service.
