How to "reindex" with Dask DataFrame

Question

I'm looking into using dask for time-series research with large volumes of data. One common operation that I use is realignment of data to a different index (the reindex operation on pandas dataframe's). I noticed that the reindex function is not currently supported in the dask dataframe API, but is in the DataArray API. Are there plans to add this function?

I believe you could use the Dataframe.set_index() method combined with .resample() for that same purpose.

Would work for evenly sampled data, but sometimes the new index we want may be arbitrary. – Michael Jun 04 '21 at 14:16
