/srv/conda/envs/notebook/lib/python3.10/site-packages/xarray/core/variable.py:1721: PerformanceWarning: Reshaping is producing a large chunk. To accept the large
chunk and silence this warning, set the option
    >>> with dask.config.set(**{'array.slicing.split_large_chunks': False}):
    ...     array.reshape(shape)
```

I simply tested var.stack(new=(""x"", ""y"")) and I got the above message.   I don't understand why From 1521 to 1527 line of xarray/core/variable.py they did reshape?

It looks like dask needs to break up the potentially-very-large intermediate chunks.


That said our strategy of transposing first means that the optimization implemented in https://github.com/dask/dask/issues/5544#issuecomment-712280433 doesn't kick in in this case.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,984555353
