- 🐎 astype('str') can be faster dispatching to to_string
- ➖ we do not really use psutil, and it can be an heavy dependency
- 🐛 fingerprints using df.copy and projecting were not deterministic
- 🐎 sparse groupby passed over original dataframe, this is faster
- ✨ datetime comparison allows string (ISO 8601 format)
- 🐛 column names equal to function names in selections/filters
- ✨ allow caching of tasks outputs
- 🐎 perform groupby in a sparse way for less memory usage/performance (~250 times faster)
