Would be good to explain what "as needed" means. "as needed" by what?
|
|
|
I don't see the point of it. When should it and shouldn't it be used ?
|
|
|
It should have been just a little bit longer with a little bit more information...explain HOW/WHY this helps the query execution

Articulated well and presented efficiently.
|
|
|
you should explain why this could be bad
|
|
|
Good inro, but want to know more about it now.
|
|
|
I want to be a part of the team doing these! :)

I do enjoy the videos that discuss the execution plan elements, these are the most helpful to me since I do a lot of query optimization work at my company.

All this video said was "There is a spool operator" and explained the difference between eager and lazy.

Explanation was too short, several more examples would have been nice.

what are situations when this would be bad and how would you detect them
|
|
|
The extra 15 seconds to explain when it is good and bad may have been worth the effort.

Lacking in any real detail. Making a video to state the most basic definition followed by a 1 line warning is pretty bad. Would've been better to make a 1 line statement describing the spool and spending some time talking about when it is good and when it could be considered a problem. If time permitted, talking about how to solve some of the most basic problems would've been nice as well though not required.

Nice but too basic!
|
|
|
Can cause problems? What problems? An extra minute with a little more explanation would have made this worthwhile.

Interesting

|

We're told that there are situations where spooling can cause problems - but then we're never told what those situations are or how to avoid them.
|
|
|
need more info like this!
|
|
|
Quick tidbit that sticks in your head.

This was a good intro, but the duration could have been extended to include some cases of when the spool operator is detrimental and how to address such a scenario.

Interesting Execution Plan topic
|
|
|
It did not tell me how to use the 'Eager Spool'.
|
|
|
very useful learning
|
|
|
Please speak a little louder
|
|
|
simple and to the point

Love to see more of these "What is a..." in the execution plan. Thanks!
|
|
|
Very short, and questions at end of video were not covered in video.
