Problem with Exercise 6

[zifeiyu87]

when I execute the following command, it has not returned a result for a long time(over 3 hours), and ultimately disconnected from the server.

1. its best to run commands in tmux or screen, to avoid disconnect.

2. the command queries a really old version S of the data: consider using c2PtAbflPkgFullU or soon to be available version V

3. the query requires going over the entire dataset, so it takes time. It would be better to break it down into smaller queries, e.g., one per 128 of the files.

@zifeiyu87, could you please verify if this issue is still relevant? Thanks
