thanks for the follow-up, @tomwhite, this looks great. However, I would remove the difference between expanded and collapsed for MemoryCachedArray since it's always a single line (see the inline comments below).

apparently, the memory cached array has to be bigger than 1e5 to be displayed as [xyz values with dtype=DTYPE], so we can either keep the test as is or increase the size. Not sure which is better, but in any case, the repr still is a single line. Thoughts, @pydata/xarray?

If we decide that we don't need to check for the repr for bigger arrays, this can be merged as soon as we stop loading the data into memory.

once we get the CI to pass, this should be ready for merging. Just note that I'm not entirely sure about the size of the test array.

This is now passing. We could add more tests or even change the representation a little in some cases, but it would be good to merge for the release (since it fixes a bug) if it looks OK to you @keewis.

I agree, this looks ready. We classified this as a release blocker so it will definitely be part of the release. Before merging I'd like to have another maintainer look over this, though, to check my decisions.
