Dump redis rdb files to json. Many limitations, including:
- Only one DB allowed
- Only plain key/vals and hashes allowed (no sets, lists, zsets for now)
3x faster than rdbtool for my test dump:
$ time rdb --command json dump.rdb > rdbtool.json
rdb --command json > rdbtool.json 264.65s user 0.80s system 99% cpu 4:25.93 total
