Comparison to binary JSON formats

Question

Closed this issue 9 years ago · 5 comments

Would be interesting to see how this compares to simply using MessagePack or CBOR for encoding.

Agreed. Although I think the binary JSON size will be comparable to just JSON gzipped, with Geobuf still having a huge benefit.

Let's make a test. Where can I find the us-zips.json and idaho.json test data from the README?

Here's the Idaho GeoJSON: https://github.com/mapbox/geojson-fixtures/blob/master/data/featurecollection/idaho.geojson
I have to upload the us-zips sample somewhere — don't want to commit it to a repo.

Interesting, I did a test with CBOR (sizes of MessagePack are virtually identical):

	normal	gzipped
idaho.json	10.92 MB	2.66 MB
idaho.cbor	7.47 MB	4.50 MB

I used 7zip with fastest setting for gzipping. I didn't expect CBOR to compress that much worse compared to plain JSON.

Ha! I knew it would be bad but didn't think it's that bad. Great!
