Concerning performance, what I have seen is that Hyper is indeed faster at querying the data. In may case, with 77 million rows, Hyper is about 40% faster. Even though this is an awesome speed improvement, I do not realize much of it because Tableau 10.5 does not draw the maps I am producing any faster than version 10.4. If all pieces of the puzzle were faster, the speed difference would be truly amazing.
Thanks for the reply.
But for the main question, when I publish the extract, it shows as .hyper format and when I download the same extract from tableau server, it shows as
.tdsx format. Is it same in your case?
My file extension says .hyper.
Even when you download the extract from the tableau server?
