By default, Python outputs spaces after commas and colons when dumping JSON data. This is normally fine, but when exporting large amounts of JSON (such as cache info) it is more space efficient to export JSON without whitespaces. To do this, simply pass
separators=(",", ":")
tojson.dumps()
.Although the space savings aren't massive, they do reduce the size of the cache folder by a couple of megabytes:
For comparison, the size of the cache folder with the
--sqlite-cache
option is about 27.5MB.
