[All AD0-E722 Questions]

An Adobe Commerce Architect is investigating a case where some EAV product attributes are no longer updated.

* The catalog is composed of 20.000 products with 100 attributes each.

* The product updates are run by recurring Adobe commerce imports that happen multiple times a day.

* The Architect finds an error in the logs that indicates an integrity constraint while trying to insert row with id 2147483647.

What is causing this error?

Show Suggested Answer Hide Answer
Suggested Answer: A, C

Option A is correct because enabling asynchronous indexing can improve the checkout performance by reducing the database load and avoiding locking issues. Asynchronous indexing allows the indexers to run in the background without affecting the frontend operations.The commandbin/magento config:set dev/grid/async_indexing 1can be used to enable this option in the production mode1.

Option C is correct because creating a new database and splitting the sales tables can also improve the checkout performance by distributing the database load and avoiding contention. Splitting the database allows the checkout and order management operations to use a separate master database from the rest of the Magento application tables.The commandbin/magento setup:db-schema:split-sales --host='<checkout db host or ip>' --dbname='<name>' --username='<checkout db username>' --password=''can be used to configure this feature2.

Option B is incorrect because enabling asynchronous email notifications does not affect the checkout performance directly. Asynchronous email notifications allow the order confirmation emails to be sent in batches by a cron job instead of immediately after placing an order.This option can reduce the server load and improve the customer experience, but it does not impact the checkout process itself3.

Option D is incorrect because there is no such deploy mode as siege in Magento 2. The available deploy modes are default, developer, and production.Changing the deploy mode can affect the performance, caching, and error handling of the Magento application, but it does not directly affect the checkout performance4.

Option E is incorrect because there is no such admin panel setting as multithreaded checkout processing in Magento 2. The number of PHP threads used for checkout is determined by the web server configuration and the PHP-FPM settings, not by the Magento application settings.Increasing the number of PHP threads may improve the checkout performance, but it also requires more server resources and may cause other issues5.

I bet the poor Magento developer who had to debug this issue had a real headache. At least they can take solace in the fact that they're not the only ones dealing with these kinds of weird database problems.

Ah, the joys of working with a large product catalog and frequent imports. This is the kind of thing that keeps us Magento architects on our toes, isn't it? I'm going with Option C as the best answer.

Hmm, an integrity constraint error while trying to insert a row with a specific ID? That sounds like a potential issue with the auto-increment column hitting its maximum value. Option C seems the most likely culprit here.

I think the error is caused by the EAV attribute import using REPLACE, reaching the max limit of the increment column.

Wow, this question is really specific! I bet the answer has something to do with that pesky 32-bit integer limit. Maybe we should start a petition to switch to 64-bit for Magento, right?

User 2: Yeah, that makes sense. It could be hitting the max limit of the column increment.

User 1: I think the error is caused by Magento framework using INSERT on DUPLICATE.

But wouldn't dropping integrity constraints, like in option B, also cause this issue?

I disagree, I believe option C is the reason for the error.
