Data joining can be done within Tableau as well like Data blending.

I am a new comer to tableau...Are these questions for senior Tableau Aanlyst or junior ? they look very technical....

Question 1 is absolutely not the answer intended at all. Do not use that answer in an interview. Data joining and blending are VERY similar with the only key difference that matters (blending = aggregation THEN joins data) vs (joining = row level join THEN aggregation)... The real answer is AVOID data blending if possible.

But,
Please explain..2:21 context filter to be used for performance improvement...while 6:16 since context filter use temp table, it recomputes, so it decreases performance....seems to be opposite facts
Also please put some more examples also despite of just going through texts
