Dear all,

I wonder why Cassandra do not support the following method:
- multi_insert: insert multi keys
- multi_remove: remove multi keys
- multi_batchInsert: batch insert multi keys


I'm not sure how the 1st and 3rd are different, but my under= standing is that this is all planned for the (near) future; there is certai= nly an issue for doing range removes (With the OrderPreservingPartitioner) = which is being actively worked on.

Multi-key inserts are also likely to be available soon if they aren'= ;t already.

Mark
