We have a specail case to handle thingwox with datastax.
I just want to add measure data set into thingworx and cassandra but data include several measured data such as measured by manual and then this data should be inserted middleware database.
Thingworx take this data after updated in kepware through interanl middleware.
It means there is two types of times, one is measued time by manual and another is thingworx create time.
In this case thingworx insert measure data in storing time instead of measure time.
But customer want to see data with measure time. But thingworx insert data with created time.
We are about to change createdate but this should be primary key and cannot be changed.
How should we resolve this problem? Otherwise do we get hiw to change primary key in Cassandra?
