Session
Although Python is popular and known for rapid development and great ecosystem, performance may often be an issue when running certain types of tasks. For example, we ran into performance issues when we had to parse and chunk CSV files of arbitrary sizes.
Utilising C for core functions and a wrapper with Cython, we were able to quickly build a lightweight Python module that improved the performance of our use case!
Through this talk, we'd demonstrate how tools like Cython could make Python even more powerful.
