Which version are you using currently in your project,is it 10.3 or 10.5? Both the versions of tableau cannot be used in same project as there would versions incompatibility and maintenance issues.
If 10.5 is your primary version then better to convert your tde to .hyper.i suggest it wil be better if you upgrade tp .hyper format as they are faster in performance when compared to tde version.
Thank you Bharat for quick info, now we are on 10.3. we are planning to upgrade it to 10.5.
how to convert .tde files from Alteryx to .hyper? going forward is .tde is not compatible from 10.5 onwards?
