Taking from the CassandaraCLI example page for simplicity, one enters the following into the
cassandra> set Keyspace1.Standard2['jsmith']['age'] = '42' cassandra> get Keyspace1.Standard2['jsmith'] => (column=last, value=Smith, timestamp=1279780450578000) => (column=first, value=John, timestamp=1279780434745000) => (column=age, value=42, timestamp=1279780457458000) Returned 3 results. cassandra> set Keyspace1.Standard2['jsmith']['age'] = '43' Value inserted. cassandra> set Keyspace1.Standard2['jsmith']['age'] = '44' Value inserted. cassandra> get Keyspace1.Standard2['jsmith'] ['age'] => (column=age, value=44, timestamp=1281297196787000) <<< 44 is the current value How could I get access to the previous values of the age column? (like values 42 and 43 and their timestamps that were entered prior to value 44) Are previous values kept or replaced in Cassandra? Is there any way to preserve and/or access column history? Thanks.
