Data scientists spend more time wrangling data than making models. Traditional tools like Pandas provide a very powerful data manipulation toolset. Transitioning to big data tools like PySpark allows one to work with much larger datasets, but can come at the cost of productivity.
In this session, learn about data wrangling in PySpark from the perspective of an experienced Pandas user. Topics will include best practices, common pitfalls, performance consideration and debugging.
