Good Morning, I'm a bit confused by your project description. First line says you have 318m files, but later in the description it says 648 files with approx 595k lines each. Can you clarify this a bit? Also, what sort of data is within the CSV files? Depending on the data-types it might be best to build a script to load the data incrementally into MySQL and use it for sorting functions, then output it back to CSV. As for encryption, we definitely can encrypt it however with this large amount of data it will add to the processing power requirement of sorting exponentially. Thanks! Keith

Hi, I offer you a better solution. I can import all your data into a back end MySQL database and can give a small PHP utility that will allow you to list the data off the database in any column order (L, J or ZIP) you want, as well as bulk deleting. This will also serve your encryption purpose as the data will reside in a professional database, not in some clear text flat file. This will also make the data more organized. You will also be able to import any new data file at any time. The application will be a PHP/MySQL solution and can be hosted on your own PC locally that will make the data transfer fastest (however, you can also put it on the web if you want to access the data over the internet from anywhere). In order to do this, I need some of the sample data files. I hope you like my idea. Regards, Joy

Hi, I've got some experience working with C, C++ and MySQL. I think I can help you out with this task if you need all the csv entries stored in a MySQL db, since MySQL will make it easier to sort and arrange data however you like. May I get some more details over the chat?

My previous job involved a lot of data manipulation and scrubbing through programming as well as through Excel. I'm also accustomed to using Python for data scrubbing and sifting over large files.

Yes, it is possible to encrypt the data. There are some caveats, we'll discuss them if I'm awarded. It's possible to do everything you have listed in MySQL also. I'm not going to lie, it won't be very fast or responsive and you're going to need to run this on properly spec'd hardware also. I'd want to write a PERL script to read() the files in chunks or by appropriate module if there is one that runs well on the target OS. Getting those files written into the database is going to be about half of the time required, waiting on sorting and debugging database server issues when sorting crashes the server is the other half. There's a lot of hurry up and wait in this one.

Hi! I have never worked with such a huge set of csv files but I know how to handle files that do not fit into memory so iz would be a very interesting project. A little more background would be nice to understand how you finally want to access this data (random access? searching for specific IDs? ...) Because I would assume that importing the data into a database would make things a lot easier but this depends on your usage scenario. best regards Thomas

I am an experienced cross platform application developer with 6+ years of experience in developing Python apps. For this project, I suggest writing scripts to read all csv files, and create one big file. Then put that data in a database (considering the format remains the same). Once in the database, any column can be sorted using SQL queries (can be executed from Python too).

I believe the best option is to import the files into a database. From there we can sort an re order the data and export again. I believe that with my wealth of experience I can get the job done. Looking forward to hear from you soon.
