But I think it would be great if it could support more data structures such as key-list, currently I am using key-value save the list, it seems not very efficiency. Redis has a good point on this but it is not easy to scale. Maybe it is a wrong place and wrong question, only curious if there is already solution about this, thanks a lot! --00151748e93a8989e004b16e5faf Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable I think cassandra is doing great job on key-value data store, it saved me t= remendous work on maintain the data consistency and service availability. = =A0 =A0But I think it would be great if it could support more data structur= es such as key-list, currently I am using key-value save the list, it seems= not very efficiency.
