@larsbuntemeyer agreed, this could be an opportunity to further reduce hard-coding of global attributes, with such items managed through a `required_global_attributes.json` input file. If there are other obvious cases like...

@mauzey1 is there a preset chunking value set in the code somewhere? I recall going over this in some detail many years ago, but a quick search of the repo...

@cofinoa we tried to optimize the deflation, shuffling and chunking settings for the best performance vs file sizes. It is a difficult balancing act, as the only way to squeeze...

@cofinoa in the https://github.com/PCMDI/cmor/issues/601#issuecomment-625134068 above there was no obvious next step regarding chunking **coordinate variables**. Have I missed something? As noted in #164, this is currently set at 1, what...

@cofinoa this issue has been stale for ~4 years, so will close. If there are additional tweaks that make sense, please comment and reopen

@cofinoa thanks for PR #733, we'll pull that in and see if there are any impacts across the test suite and some usage file sizes, and merge into the planned...

#733 merges the changes, but we need to add a test to ensure that we're not a) breaking anything, and b) not causing performance issues for "standard" datasets - for...

@mauzey1 this seems like a trivial update, I'll label this against the 3.9.0 milestone as it would be useful to cleanup if there is a sensible solution @taylor13 ping
