I want to get a file in azure blob storage and using event trigger function, I want to convert this csv file into parquet format and upload it to another blob storage. I tried to use choparquet reader, but it takes a lot of time to convert the file to parquet format and when a large files comes, few events are missed from the queue and not all files are this converted in to parquet format. I am using c#

Can anyone help in simplified approach to this problem?

    @Amey Pimpley
    Unfortunately I do not have experience working with parquet. Since you are working with c# your options are somewhat limited. I was able to find the Parquet.Net package which should be able to accomplish this. I found a blog post which shows how you can use the package to convert data. Please review this and see if it works for you.

    Hope this helps! Let us know if you have further questions or issues.
