BTW, maybe we should create an issue on jira for this problem if the
Cassandra committee think it is necessary.

delete one key permanently, my guess
is that cassandra won't delete the key at once just mark the deleted
keys. So when will cassandra do the real deletion operation?

Hi all,
I made too many requests to cassandra , and then after a while, I can
not connect to it. But I can still connect it from another machine ?
So does it mean cassandra will block client in some situation ?

can use to resolve this problem, what parameter I can use to tune the
program ?

Yes, we are in a rush at the beginning of this prototype.
Now the code structure looks better.

Hi all,
It seems the api of cassandra is a little different from hbase, I am looking
for the api for list all the columns under one column family ? Is there any
way to do this ? Thanks.

Hi all,
I'd like to use Cassandra to store small files, so I wonder whether
Cassandra has size limitation on value ?

Hi all,
I'd like to check whether one key exist, currently my solution is to let the
cassandra use the OrderPreservingPartitioner, and facilitate the
get_key_range() API to check key's existence. I wonder whether there's other
ways to do this ? Thanks.

found that only
the first 4 machines are in the ring by using command
*bin/nodeprobe -host 10.148.219.12 ring*
It looks like the other two machines in different subnet can not been
gossiped. Anyone has ideas? How can I solve this problem ?
