Configuring many attribute options can affect site performance in the following ways:

Long request and rendering times on product detail (PDP) and category pages containing complex products.
Admin product save operations response time increases above optimal performance targets.
Increase in Product Edit form rendering time.
Slow checkout.

Increases in product data and index sizes can affect site performance in the following ways:

Increased response time for most storefront scenarios related to catalog browsing, search (quick and advanced), and layered navigation.
Product management operations in the Admin slow significantly which can lead to timeouts.
Product Mass Actions functionality can be blocked.
Index re-build time for mid- and large-sized catalogs cannot be performed on a daily basis due to long execution times.

Configuring many product attributes increases the product template size for each product (EAV structure) and the amount of data that must be retrieved. This increase affects operations in the following ways:

Increase in SQL queries traffic related to EAV data retrieval and the amount of data processed which results in decreased DB throughput
Significant increase in the size of Adobe Commerce indexes and the full-text search index
Reaching hard MySQL limits when building a FLAT index for oversized product templates and inability to use it

If you have more than 48 products in any category, update the storefront catalog configuration to disable the option to ———–

Allow All Products per page.

For versions 2.3.x - 2.4.2, allow a maximum of —- products in a cart.
For versions 2.4.3 and later, enhancement to sales rules capabilities increased the cart maximum to —-.

100,750

For versions 2.3.x - 2.4.2, the expected performance based on cart item limits is:

Up to — products in a cart—the product works, meeting performance targets for response time.
Up to —- products in a cart—the product works, but response time increases above targets.
Above —– products in a cart—the cart and checkout flows are not guaranteed to work

100,300,500

Use the following strategies to manage the number of cart items

Split orders into several smaller orders with a smaller number of rows by using the Add Item by SKU feature.
Only add the custom logic and cart customization required to load a list of items.

Having more than the recommended maximum number of products in the cart can affect site performance in the following ways:

Increased response time for data retrieval operations, validation of cart items, checks for applying price rules, and tax and total calculations.
Increased response time for minicart rendering including rendering of cart views, checkout flow, and execution.
Increased time loading time for all site pages where the minicart is present.

If your project requires many sites, stores, or store views, you can use the following strategies to improve performance:

Restructure catalog by shifting logic to categories Separate price lists from catalog data by using external price and a Price Management System (PMS). Use an alternative noSQL data storage like Elasticsearch

Websites and stores are multipliers for catalog data, so having many websites and stores can negatively affect site performance in the following ways:

Larger index tables increase time required to complete indexing operations [Price index]. Increased time to retrieve application configuration degrades storefront response time for non-cached catalog pages. Significant increases in the time required to complete Save operations in the Admin since the data is saved separately for each website.

If you do not use the Reports or dynamic customer segments, disable the Reports functionality.

From the Admin, navigate to Stores > Settings > Configuration > General > Reports. Under General Options, set Enable Reports to No. Flush cache by running php bin/magento cache:flush or in the Admin under System > Tools > Cache Management.

Adobe recommends using the----- database engine. In a default Adobe Commerce installation, all tables in the database are stored using the InnoDB engine. However, some third-party modules (extensions) can introduce tables in the------- format. After you install a third-party module, check the database to identify any tables in ----- format and convert them to ---- format.

InnoDB MyISAM myisam innodb

run the following query to determine whether the database has any MyISAM tables:

SELECT table_schema, CONCAT(ROUND((index_length+data_length)/1024/1024),'MB') AS total_size FROM information_schema. TABLES WHERE engine='myisam' AND table_schema NOT IN ('mysql', 'information_schema', 'performance_schema', 'sys');

Change the storage engine to InnoDB

In the db_schema.xml file declaring the table, set the engine attribute value for the corresponding table node to innodb

To determine which search engine is currently in use, run the following command:

./bin/magento config:show catalog/search/engine

For Adobe Commerce 2.4.4 and later, use the ----------for native MySQL search. For earlier Adobe Commerce versions, use------------

OpenSearch service Elasticsearch

Triggers are used to log changes into ----- tables. Adobe recommends configuring the application to write directly to the audit tables instead of using the ---- functionality for these reasons:

audit, trigger

Triggers are interpreted as code and MySQL does not precompile them. Hooking onto your query’s transaction space, they add the----- to a parser and interpreter for each query performed with the table. The triggers share the----- transaction space as the original queries, and while those queries compete for---- on the table, the triggers independently compete on locks on another table.

overhead, same, locks

To avoid potential issues with cron deadlocks, upgrade ECE-Tools to version ------

2002.0.21 or higher.

Switching indexers generates data definition language (DDL) statements to create---- which can cause -----. You can prevent this issue by putting your website in ------ and disabling------ before changing the configuration.

triggers,database locks,maintenance mode, cron jobs

Avoid running----- in the Production environment to prevent conflicts (like table modifications and creations). The setup:upgrade process is an exception.

DDL statements

If you need to run a DDL statement, put the website in ----- and -------(see the instructions for switching indexes safely in the previous section).

Data definition language (DDL) statements let you to perform these tasks: ...... schema objects. .....privileges and roles. Analyze information on a table, index, or cluster. Establish.... options.

how to make Makes continuous integration build faster?

by reusing unchanged code

what is a slug?

The result of the build phase is a read-only file system named slug, This phase creates an archive and places the slug in permanent storage. The next time you push code, if a service did not change, it uses the slug from the archive.

The slug includes all files and folders excluding the following mounts configured in magento.app.yaml:

"var": "shared:files/var" "app/etc": "shared:files/etc" "pub/media": "shared:files/media" "pub/static": "shared:files/static"

what does build phase do?

This phase builds the codebase and runs hooks in the build section of .magento.app.yaml

what phase , compresses static files using GZIP, and deploys the files, which reduces downtime in the deployment phase?
