質問 1

An Adobe Commerce Developer has written an importer and exporter for a custom entity. The client is using this to modify the exported data and then re-importing the file to batch update the entities.
There is a text attribute, which contains information related to imagery in JSON form, media_gallery. This is not a field that the client wants to change, but the software they are using to edit the exported data seems to be modifying it and not allowing it to import correctly.
How would the developer prevent this?
A) Specify a serializer class for the attribute using the $_transformAttrs class property array for both the exporter and importer so it gets converted:

B) Strip the attribute from the imported file by adding it to the s_strippedAttrs class property array:

質問 6

An international merchant is complaining that changes are taking too long to be reflected on the frontend after a full product import.
Thinking it may be database issues, the Adobe Commerce developer collects the following entity counts:
* Categories: 900
* Products: 300k
* Customers: 700k
* Customer groups : 106
* Orders: 1600k
* Invoices: 500k
* Creditmemos: 50k
* Websites : 15
* Stores : 45
What is a probable cause for this?

A. The combination of the number of orders, customers, invoices and creditmemos is too big. This leads to a huge amount of values being stored in the customer grid index which is too large to be processed at a normal speed.

B. The combination of the number of products, customer groups and websites is too big. This leads to a huge amount of values being stored in the price index which is too large to be processed at a normal speed.

C. The combination of the number of products, categories and stores is too big. This leads to a huge amount of values being stored in the flat catalog indexes which are too large to be processed at a normal speed.
