I tried what you suggested (with a small subset, the source files are quite large) and it seems to work on smaller subsets, writing locally. Which leads me to suspect trying to run the same process with larger datasets might be overloading memory, but I can't assert the root cause yet. This isn't blocking my current strategy so closing for now.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,493058488

One thing I'm not sure of how to make reproducible is calling a remote file store, since I think it usually requires calling to a write-protected cloud storage provider. Any tips on this?

I have what should be an otherwise working example here: https://gist.github.com/abarciauskas-bgse/d0aac2ae9bf0b06f52a577d0a6251b2d - let me know if this is an ok format to share for reproducing the issue.

It seems related to the source dataset's variables. When I use 2 opendap urls with 4 parameterized variables things work fine

Using 2 urls like:

```
https://podaac-opendap.jpl.nasa.gov:443/opendap/allData/ghrsst/data/GDS2/L4/GLOB/JPL/MUR/v4.1/2002/152/20020601090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc?time[0:1:0],lat[0:1:17998],lon[0:1:35999],analysed_sst[0:1:0][0:1:17998][0:1:35999],analysis_error[0:1:0][0:1:17998][0:1:35999],mask[0:1:0][0:1:17998][0:1:35999],sea_ice_fraction[0:1:0][0:1:17998][0:1:35999]
```

I get back a dataset :

```
<xarray.Dataset>
Dimensions:         (lat: 17999, lon: 36000, time: 2)
Coordinates:
  * lat             (lat) float32 -89.99 -89.98 -89.97 ... 89.97 89.98 89.99
  * lon             (lon) float32 -179.99 -179.98 -179.97 ... 179.99 180.0

    analysed_sst    (time, lat, lon) float32 dask.array<shape=(2, 17999, 36000), chunksize=(1, 1000, 1000)>

    Conventions:                CF-1.5

```

however if I omit the parameterized data variables using urls such as:

```
https://podaac-opendap.jpl.nasa.gov:443/opendap/allData/ghrsst/data/GDS2/L4/GLOB/JPL/MUR/v4.1/090000-JPL-L4_GHRSST-SSTfnd-MUR-GLOB-v02.0-fv04.1.nc
```

I get back an additional variable:

```

  * lat               (lat) float32 -89.99 -89.98 -89.97 ... 89.97 89.98 89.99

In the first case (with the parameterized variables) I achieve the expected result (data is stored on S3). In the second case (no parameterized variables), `store` store is never included in the graph the workers seem to stall.
