i use get_range_slice to get the list of keys,
then i call client.remove(keyspace, key, columnFamily, timestamp,
ConsistencyLevel.ALL);
to delete the record
but i still have the keys.
why?
can i do it otherwise?
take care
of encoding for you.

You can get the best of both worlds by repeating the key in a column,
and creating a secondary index on that column.

You're better served using UUIDs
i use jdk1.6 to install and launch cassandra in a linux platform,but can i use
jdk1.5 for my cassandra Client ?
in my java application,when we try to insert we should all the time know the
last rowId
in order the insert the new record in rowId+1,so for that we should save this
rowId in a file
is there other way to know the last record rowId?
thanks

i see that the problem happens when i try to remove records from my application
but these records were created before from CLI.
is there a explication for this?

i use cassandra database replicated in two servers,when want to delete a record
using this line :

but when i check,i see that the record still exist!
any idea
BR
a storage-conf.xml is read just at the starting of cassandra?
is there a way to add a column family dynamically?

You need to design your schema carefully as your application needs.
