CSV File Splitter written in RustThis repo contains both the Rust implementation of the CSV splitter as well as thecsv-split.rb file from this repo.When working with really large CSV files, it takes a very long time for the ruby version to finish. I decided to rewrite this tool inRust to improve the performance and to improve my Rust knowledge.BenchmarksI ran each sample file 5 times through the programs to give me the average run time for each file size.I've included a ./sample-data.csv file in this repo to provide a sample of the data that was used while running these tests.The only difference is the number of rows in the file, but the data was consistent in each row.The highest number of rows that I was able to run the rust program was around 30 million. The file size was 818MB. It ran in about ~12 seconds when using 10000 as the batch size. I tried to add another 5 million to it (35 million total with around 920MB file size), but the process would get killed every time. There are probably some memory improvemnets that we could make to help with this limitation, but hopefully this won't be a huge problem for anyone.LanguageFile SizeLine CountBatch SizeAvg.

Thanks.E.g.:And the CSV file in attachment.You can't currently use the companion app to import csv files in order to split up PDFs. For that, you have to transfer the file to the device, then use Import->CSV or PDF Bookmarks to select the csv file.

MikeActually, it didn't work.I uploaded both files to my OneDrive.I imported the PDF from the App itself (not the Companion this time) with the OneDrive connexion.As it was not possible to import the CSV file directly from the App with the OneDrive connexion, I first downloaded it locally on phone with the OneDrive app and I imported the CSV from the app itself.There, I had an error message telling that there were no matching PDF.-- 2nd attempt --I downloaded manually both the PDF and the CSV with the OneDrive app locally on my phone.I imported the PDF from the local storage.I imported the CSV from the local storage.Then it worked.Conclusion: in order to import files with bookmarks, the OneDrive connexion, the PC Companion are not useful, correct ?LaurentGet the pdf and the csv into one folder on the device with MSP. Then 'songs import'>'csv/pdf bookmarks' >storage location of the pdf/csv>select file and import. Note I haven't done this much so the directions may be missing step[s]. The most important info is the pdf and the csv must be in the same folder [and on the MSP device?] to do a csv/pdf import....and also important: the csv and the PDF have to have the same name.
