Hi - We are designing a Cassandra based storage for the following use cases-
* Store SMS messages * Store MMS messages * Store Chat history What would be the ideal was to design the data model for this kind of application ? I am thinking on these lines .. Row-Key : Composite key [ PhoneNum : Day] * Example: 19876543456:05022013 Dynamic Column Families * Composite column key for SMS [SMS:MessageId:TimeUUID] * Composite column key for MMS [MMS:MessageId:TimeUUID] * Composite column key for user I am chatting with [UserId:198765432345] - This can have multiple values since each chat conv can have many messages. Should this be a super column ? 19866666666:05022013 SMS:xxxx:ttttttt SMS:xxx12:ttttttt MMS:xxxx:ttttttt XXXX:1933333333 19877777777:05022013 19878888888:05022013 Thanks, Kanwar
