I took some time to play with this, so I can provide an anecdotal report. I compared three setups: - This branch with `split_file_groups_by_statistics = true` - main with `split_file_groups_by_statistics = true` - main with `split_file_groups_by_statistics = false` I used datafusion-cli, with `datafusion.execution.collect_statistics` always set to `true`. Dataset contains ~90 files, `n_cpus=60`. So at default settings, there are at most 2 files per file group. Table created with: ``` -- This is an automated message from the Apache Git Service.
