streaming dump_data
`dumpdata` without `MemoryErrors`, with progress notification. Most of the real work is done by snippets [1400](http://www.djangosnippets.org/snippets/1400/) and [1401](http://www.djangosnippets.org/snippets/1401/). ./manage.py dumpdata_stream --format=xml > big_dump.xml This is basically the stock Django `dumpdata` with a few modifications. Django devs: it's hard to reuse parts of most Django management commands. A little refactoring could go a long way.
