The link to the dashboard will … WebIt’s sometimes appealing to use dask.dataframe.map_partitions for operations like merges. In some scenarios, when doing merges between a left_df and a right_df using map_partitions, I’d like to essentially pre-cache right_df before executing the merge to reduce network overhead / local shuffling. Is there any clear way to do this? It feels like it …
