> Assuming the initial delay is the time it takes to list all files - do you think that saving the dataset without partitions might make it faster? It's worth benchmarking. Are these files local? Or onS3? > Or can I save somehow the indexes of the files in advance? If you have the list of filenames (which you can save in whatever format you want) and the dataset schema (which you can save as an empty arrow/parquet file) then you can do: ``` table = ds.dataset(list_of_paths, schema=dataset_schema).to_table() ``` -- This is an automated message from the Apache Git Service.
