In the following patch you can see coll inserts the wrong indexes against the data I am inserting. Im wondering why this is? Should I not be using indexes and instead inserting the first column as symbol?
look what will happen if you send two times the same message , eg [insert 100 Device],[insert 100 Device].
As you are "inserting" [Coll] will increase your index . you need to use [store] message instead.
