Hello all, I know organization is a broad topic and everybody may have an idea on how to do it, but I really want to have some advices and opinions and I think it could be interesting to discuss this matter.
Here is my problem: I am designing a messaging system internal to a website. There are 3 big structures which are Message, MessageList, MessageBox. A message/messagelist is identified only by an UUID; a MessageBox is identified by a name(utf8 string). A messagebox has a set of MessageList in it and a messagelist has a set of message in it, all of them being UUIDs. Currently I have only two CF : message and message_time. Message is a UTF8Type (cassandra 0.6.11, soon going for 0.8) and message_time is a TimeUUIDType. For example if I want to request all message in a certain messagelist I do : message_time['messagelist:uuid(messagelist)'] If I want information of a mesasge I do message['message:uuid(message)'] If I want all messagelist for a certain messagebox ( called nameofbox for user openvictor for this example) I do : message_time['messagebox:openvictor:nameofbox'] My question to Cassandra users is : is it a good idea to regroup all those things into two CF ? Is there some advantages / drawbacks of this two CFs and for long term should I change my organization ? Thank you, Victor
