With normal use case I meant saving legitimate object arrays.

That would be around 150 years of daily data (180\*360\*150\*365). I am not sure though how much sense it makes to have such a large array with object dtype. Also an array of this size is likely a dask array and there is already a performance warning on this. So I'd say go ahead. https://github.com/pydata/xarray/blob/68d3c340304ccc57cac569b22781e2b9c3dac913/xarray/conventions.py#L194-L197","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,768981497
