Dataframe merges

what’s the best way to do a dask dataframe merge between two unequally sized partitioned dataframes?

Hi @jooglyp! I think your best resource is probably this page in the Dask docs, which goes over the different types of joins. If one of your dataframes is small enough to be a single partition or if both dataframes are easily indexed (and you can join along the index) then it’ll be much faster. There are also a few examples on the best practices page.
