From what I have read, the PBI Storage engine represents TimeStamp values as a Double. Which means that it does not do any optimized storage (RLE, HashTable, value compression).
We are creating fairly large FactTables, that are index'ed by a Timestamp (We do IOT work, and this is network telementry that has a timestamp and a few other values).
We don't need granularity more than an hour, but by my calculations, even if you go into Seconds since 1900, there is plenty room in a 64 bit integer to store all the days.
No, we don't want to create our own version of TimeStamp. Sounds like a simple feature to test if the value is aligned to a minute or a second, the storage engine could optimize the storage for the value using an 64bit integer.
This is a feature request. Is this a good place to add it?
