Re: another chunking question - when should chunking NOT be used

Howdy all!

Another question relating to chunking - if we don't need it (i.e. for
a dataset with no unlimited dimensions), do we still chunk it?

Or is it better to leave it contiguous?

(With the mental reservation that only chunked datasets will be able
to take advantage of compression, when we get to that feature.)

Thanks!

i would be inclined to say that the default should be the old netcdf layout (continuous) just because that is optimal for sequential processing, which is a reasonnable assumption. but the previously suggested 3 modes could still be used, regardless of whether unlimited dimesnions are used or not.
