I'm struggling with creating a mixin with sass and I can't seem to find a solution. If anyone has any ideas... I have something like this:

I'd like to know how to do 2 execution plans: "traditional" execution plan joins (A with B) and then C. The "new" plan joins (A with B) then (A with C) and then joins the result of those joins so there would be 3 joins. How would I code the traditional and new plan in Oracle SQLPlus given the code below? I also need to measure the time complexity of both methods to show that the new plan takes less time, which I believe I just do with set timer on; The joins can be on whatever attributes work. Same with select statements. I made a artist, b album, c track, and d played.

Here's the database:

While trying to find the most efficient way to filter dictionaries, I stumbled upon a strange behaviour.

I made 4 tests, the first one filters the dictionary sequentially.

The second one does a single filtering with a combination of the rules (which is actually the most efficient way).

Then, I made attempt to make it more generic so that the filter may be used with an arbitrary number of predicates, that could be eventually user-defined, not hard-coded.

And I realised that combining predicated with all was much more inefficient than doing two filterings one after the other.

What can explain this ? Is this the all() function that has poor performance ? Would you suggest any other way to improve performance still in a generic way ?

I have this kind of input JSON file for my Neo4J database :
