Keys for deleted rows visible in CLI
Hello,
I searched the archives and it appears that this question was once asked but
was not answered. I just deleted a lot of rows, and want to "list" in
cli. I still see
the keys. This is not the same as getting slices, is it? Anyhow, what's
the reason
and rationale? I run 0.8.8.
Thanks
Maxim

Thanks, it makes perfect sense now. Well an option in cassandra could
make it optional
as far as display it concerned, w/o performance hit -- of course this is
all unimportant.
Thanks again
Maxim

I agree. Open JIRA for it.

Thanks. It could be hidden from a human operator, I suppose :)

Hi Maxim,
The reason for this is because if node 1 goes down while you deleted information on node 2, node 1 will know not to repair the data when it comes back again. It will know that an operation has been performed to delete the data.

Hello,
I searched the archives and it appears that this question was once asked but was not answered. I just deleted a lot of rows, and want to "list" in cli. I still see the keys. This is not the same as getting slices, is it? Anyhow, what's the reason and rationale? I run 0.8.8.
Thanks

The cli's 'list' command is the same as get_range_slices(), which is the
one type of query where you can get back range ghosts (deleted keys).
