Another example of an issue that's very hard to pin down is https://github.com/zarr-developers/zarr-python/issues/528.

Btw we have also run into issues with fsspec caching directory listings and not invalidating the cache when store changes are made, although I haven't checked with latest master. We have a lot of workarounds in our code where we reopen everything after we've made changes to a store. Probably an area where some more digging and careful testing may be needed.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,576337745

However, writing or deleting keys should invalidate the appropriate part of the cache as it currently stands, so I don't know why the problem has arisen. If it is a cache problem, then `s3.invalidate_cache()` can always be called.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,576337745
