If you run import modin.pandas as pd, the following operations are available from pd.<op>, e.g. pd.concat. If you do not see an operation that pandas enables and would like to request it, feel free to open an issue. Make sure you tell us your primary use-case so we can make it happen faster!
The following table is structured as follows: The first column contains the method name. The second column is a flag for whether or not there is an implementation in Modin for the method in the left column. Y stands for yes, N stands for no, P stands for partial (meaning some parameters may not be supported yet), and D stands for default to pandas.
Note
Currently, the second column reflects implementation status for Ray and Dask engines. By default, support for a method in the HDK engine could be treated as D unless Notes column contains additional information. Similarly, by default Notes contains information about Ray and Dask engines unless Hdk is explicitly mentioned.
| Utility method | Modin Implementation? (Y/N/P/D) | Notes for Current implementation |
| pd.concat | Y | Hdk: Y but sort and ignore_index` parameters ignored |
| pd.eval | Y | |
| pd.unique | Y | |
pd.value_counts |
Y | The indices order of resulting object may differ from pandas. |
| pd.cut | D | |
| pd.to_numeric | D | |
| pd.factorize | D | |
| pd.from_dummies | D | |
| pd.qcut | D | |
pd.match |
D | |
| pd.to_datetime | D | |
| pd.get_dummies | Y | |
| pd.date_range | D | |
| pd.bdate_range | D | |
| pd.to_timedelta | D | |
pd.options |
Y |
This list is a list of objects not currently distributed by Modin. All of these objects are compatible with the distributed components of Modin. If you are interested in contributing a distributed version of any of these objects, feel free to open a pull request.
