Hi there,

Is there already support for doing somethi= ng 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 k= ey, different value and different timestamp, would i still be able to retri= eve both versions?

Looking at the API I can not find such met= hod, but perhaps I am missing something as I am new to cassandra.

Best regards,
Bram
