By using cassandra-cli tool, we don't have to input timestamp while insertion. Does it mean that Cassandra have time synchronization build-in already? Since cassandra depending on time-stamp parameter very much (both read/write). The most ideal way to deal with timestamp is by cassandra itself, considering data safty and consistensy....
Kuan -----Original message----- From:Michal Augustýn <augustyn.mic...@gmail.com> Consider situation when you have more Cassandra servers. It would require time synchronization in Cassandra itself. So we have to have time synchronization - on applications servers or Cassandra servers. I'm not sure if this is concern of Cassandra but it would be good for me... 2010/9/20 Kuan <lakersg...@mail2000.com.tw> To whom it may concern, While timestamp parameter is auto generated by using cassandra-cli tool, why user have to manually insert the parameter in Cassandra-Thrift "insert" API?? In my point of view, leaving time-stamp to be inserted by client side will lead data into chaos, since clients' local time might be vary.... Time-Stamp better be generated automatically and consistently by Cassandra Server itself isn't it? Any idea?? Best, KuanSheng Taipei
