AD0-E716 Exam Dumps : Adobe Commerce Developer Expert

To ensure the developer has access to push code in an Adobe Commerce Cloud project, the developer’s email must be added under Users in the Cloud Project Web UI and the developer needs to add SSH public key in the Cloud Account dashboard settings. The Cloud Project Web UI is a web interface that allows managing and configuring Adobe Commerce Cloud projects and environments. The developer’s email must be added under Users to grant them access to the project and assign them a role and permissions. The Cloud Account dashboard settings is a web interface that allows managing and configuring Adobe Commerce Cloud accounts and SSH keys. The developer needs to add SSH public key in the settings to enable secure connection to the project and environments via SSH. Verified References: [Magento 2.4 DevDocs]

Decreasing the batch size value improves performance by reducing the memory usage for the temporary table. The batch size value determines how many rows of data are processed at a time by the indexer. A large batch size value can cause the allocated memory size for the temporary table to exceed 20% of innodb_buffer_pool_size, which can result in errors and slow down the indexing process. By lowering the batch size value, the indexer can process the data more efficiently and avoid memory issues. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

The error message regarding innodb_buffer_pool_size indicates that the temporary table’s memory usage is high. Decreasing the batch size value directly reduces the number of rows processed in each batch, which in turn reduces the memory requirements for the temporary table.

Impact of Batch Size on Memory Usage:

The batch size determines how many records are processed at one time. By lowering the batch size, fewer records are processed, which reduces the amount of temporary table memory needed, alleviating the pressure on the InnoDB buffer pool.

When the memory required by temporary tables exceeds the InnoDB buffer pool limit, MySQL might swap to disk, leading to slower performance and increased I/O.

Why Option A is Correct:

Reducing the memory footprint of temporary tables helps to prevent situations where memory constraints slow down or disrupt indexer operations.

Options B and C are incorrect as they do not directly impact memory usage. Batch size adjustments do not affect timeout settings or PHP thread usage.

Recommendations:

In addition to adjusting the batch size, consider optimizing the innodb_buffer_pool_size setting based on server capacity to better handle larger operations if needed.
