Are there any plans to add versioning in the near future to cassandra? What is the purpose of the timestamp in the current implementation? Best regards, Bram

(Bram) van der <bram.vanderwa...@tno.nl> Hi there, Is there already support for doing something with the timestamp? I would like to use it as a versioning mechanism of the value belonging to a certain key. When i store a column with the same key, different value and different timestamp, would i still be able to retrieve both versions? Looking at the API I can not find such method, but perhaps I am missing something as I am new to cassandra.
