Hi @osrecio. Thank you for your contribution
Here are some useful tips how you can test your changes using Magento test environment.
Add the comment under your pull request to deploy test or vanilla Magento instance:

• @magento give me test instance - deploy test instance based on PR changes
• @magento give me 2.4-develop instance - deploy vanilla Magento instance

❗ Automated tests can be triggered manually with an appropriate comment:

• @magento run all tests - run or re-run all required tests against the PR changes
• @magento run <test-build(s)> - run or re-run specific test build(s)
  For example: @magento run Unit Tests

<test-build(s)> is a comma-separated list of build names. Allowed build names are:

1. Database Compare
2. Functional Tests CE
3. Functional Tests EE,
4. Functional Tests B2B
5. Integration Tests
6. Magento Health Index
7. Sample Data Tests CE
8. Sample Data Tests EE
9. Sample Data Tests B2B
10. Static Tests
11. Unit Tests
12. WebAPI Tests
13. Semantic Version Checker

You can find more information about the builds here

ℹ️ Run only required test builds during development. Run all test builds before sending your pull request for review.

Hi @osrecio,
Your changes look good to me.
Could you please provide steps to reproduce the issue?

Hi @ihor-sviziev ,

I added some manual steps, seems like in the previous PR, not all possibilities were covered.

In this PR, when you try to reindex EAV, the query can be vary from:

• [before] with quotes -> 7882 rows in set (34.460 sec)
• [after] no quotes -> 7882 rows in set (0.086 sec)

[ihor-sviziev]

@osrecio thank you!

@magento run all tests

PS: Added label of "auto-tests: not required" because such case would be really hard to test automatically + it's reproducing the only on some specific environments (MariaDB should be used as a DB)

The requested builds are added to the queue. You should be able to see them here within a few minutes. Please re-request them if they don't show in a reasonable amount of time.

@magento create issue

Hi @osrecio & @ihor-sviziev Thanks for your contribution and collaboration!
I tried to test the performance improvements with the fixes and below is my observation

1. Made sure that, I have products with the count 50k+, that I got using performance toolkit file large.xml.
2. From the Magento root directory, executed the command: php bin/magento indexer:reindex catalog_product_attribute
3. Noted the time taken and it was Product EAV index has been rebuilt successfully in 00:08:32
4. Later, I pulled this PR file changes into my current Magento instance, and re-ran the same command.
5. Observed that, the tike taken is Product EAV index has been rebuilt successfully in 00:08:34. Below is the screenshot of prior code changes and after code changes output.

Here, noticeable thing is, it has taken 2 seconds more time to the prior file changes execution. I re-tried the same scenario twice in my system and found the same 2 seconds more time taken both the times.
Can you please check once and let me know if I have missed anything here. Or whether may require any more code changes from your end too!

Hi @osrecio ,

Thanks for your contribution and collaboration.

As per your comment it should take very less time to reindex EAV.

In this PR, when you try to reindex EAV, the query can be vary from:

[before] with quotes -> 7882 rows in set (34.460 sec)
[after] no quotes -> 7882 rows in set (0.086 sec)

But I have observed It is still taking longer time to reindex EAV. Below are the steps which I have followed -

1. Installed magento 2.4-develop using mariadb.
2. Creating 5 lakh products using performance fixtures (large profile)
3. Ran bin/magento indexer:reindex catalog_product_attribute

Time taken before PR change:

Time taken after PR change:

From above screenshots we can see time difference is only 1 min. Can you provide information about it.

Thanks
