I have been faced with a problem of grouping composites on the second-part.
Lets say my CF contains this TimeSeriesCF key: UserID composite-col-name: TimeUUID:PKID Some sample data UserID = XYZ Time:PKID Col-Name1 = 200:1000 Col-Name2 = 201:1001 Col-Name3 = 202:1000 Col-Name4 = 203:1000 Col-Name5 = 204:1002 Whenever a time-series query is issued, it should return the following in time-desc order. UserID = XYZ Col-Name5 = 204:1002 Col-Name4 = 203:1000 Col-Name2 = 201:1001 Is something like this possible in Cassandra? Is there a different way to design and achieve the same objective? -- Ravi
