I am trying to fix #1775, but tests are still failing.
Any help would be appreciated.",2017-12-12T15:22:07Z,2019-09-25T15:44:19Z,2018-01-09T01:48:13Z,2018-01-09T01:48:13Z,ab0db05a58fd47fe895d1a85c09c37d96263d3b7,,3008859,0,e27c043adb96e027ac51e9d1abdf88e20db8dd7b,c368ee734945bbc736c33463ea561311bbdc1e9b,MEMBER,,13221727,https://github.com/pydata/xarray/pull/1776,

Right now, I've just modified the dask distributed integration tests so we can all see the [failing tests](https://travis-ci.org/jhamman/xarray/jobs/317603224#L4400-L4571). 

I'm happy to push this further but I thought I'd see if either @shoyer or @mrocklin have an idea where to start?",2017-12-19T22:24:41Z,2018-03-13T15:32:54Z,2018-03-10T15:43:18Z,2018-03-10T15:43:18Z,2f590f7d7f34c7dfddea4d1d4f8877bca081b601,,3008859,0,3c2ffbf5b85299a59e0fa12fdec8dff03346527f,870e4eaf1895cfeffdc27dab61ad739e67133777,MEMBER,,13221727,https://github.com/pydata/xarray/pull/1793,

This is building on top of #1799. Based on the suggestion from @alimanfoo in https://github.com/pangeo-data/pangeo/issues/48#issuecomment-353807691, I have reworked the handling of attributes in the zarr backend. There is more to do here, particularly in the `set_dimensions` arena but this is giving almost a 2x speedup in writing to GCP.
