Report of 300.000 lines in 0.4 seconds!
Created with Elixir.
Made with ❤️
- Generate reports of 300,000 different food dishes
- Use of parallel processes to generate the report in up to 0.4 seconds
- Single process option (for comparisons) of up to 1.1 seconds
- Elixir
- Erlang
SSH URLs provide access to a Git repository via SSH, a secure protocol. If you have an SSH key registered in your GitHub account, clone the project using this command:
git clone git@github.com:LuizFerK/Parallelixir.git
In case you don't have an SSH key on your GitHub account, you can clone the project using the HTTPS URL, run this command:
git clone https://github.com/LuizFerK/Parallelixir.git
Both of these commands will generate a folder called Parallelixir, with all the project
- Run
mix deps.get
to install the dependencies - This project does not have a server, in this case, the mode of use is through IEx (Elixir's interactive shell), which can be accessed using the command
iex -S mix
in the project folder - Within IEx, you have two usage options: standard execution (which will run 300 thousand lines in just one process) and parallel execution (which will run 3 files of 100.000 lines simultaneously). To use the standard mode, run the following command:
ReportsGenerator.build("report_complete.csv")
- If you want to use the parallel mode, run the following command:
ReportsGenerator.build_from_many(["report_1.csv", "report_2.csv", "report_3.csv"])
- In both modes, you will have the same result, however, parallel execution will be faster
- The result will be a map with the following information:
foods
(representing the total times that every food appears in the files) andusers
(representing the total times that every user appears in the files), as you can see below:
