Method 2: Admin Panel/ Backend Interface Reindexing

Reindexing in Magento 2's admin panel offers two modes:

1. Update on Save Mode: In this mode, the index tables immediately update when dictionary data changes. It captures changes immediately after any save action, leading to prompt index updates. The index management page also updates and flushes reindex messages.

2. Update by Schedule Mode: This mode schedules index updates using a cron job. It defines intervals for reindexing and writes updates to the index during Magento cron job execution.

To reindex through the admin panel in Magento 2, follow these steps:

1. Log in to the Magento 2 Admin Panel.

2. Navigate to System > Tools > Index Management category in the admin panel.

3. Select the Checkbox next to each type of indexer you want to modify.

4. From the Action List, choose the Indexing Mode.

5. Finally, click the Submit button to apply the selected mode to the indexers.

Optimizing the Magento Default Reindexing Process

Reindexing in Magento 2 can be complex, particularly when using the default method. This process can be time-consuming and lead to slower storefront performance.

It also requires technical expertise and access to SSH or CLI, which can be challenging for store owners lacking coding experience. To overcome these challenges and optimize the reindexing process:

1. Schedule Off-Peak Reindexing

Analyze your store's analytics data to determine the hours or days when customer activity is lowest. Use this information to create a reindexing schedule that aligns with these periods. Automate the scheduling process if possible to ensure consistency.

2. Choose Indexing Modes

Assess your store's needs and priorities. If you need real-time updates, choose Update on Save. If performance is a higher concern, consider the Update by Schedule mode, which spreads out indexing tasks over time. Experiment with both modes to find the best fit for your Magento ecommerce.

3. Explore User-Friendly Tools

When exploring Magento extensions or tools tailored to your Magento version, conducting thorough research is essential. Begin by reading user reviews and seeking recommendations within the Magento community. Prioritize solutions that offer clear documentation and reliable customer support.

4. Monitor and Address Failures

Establish monitoring alerts to receive real-time notifications of reindexing failures. When a failure occurs, investigate the root cause. It involves checking your server setup, ensuring correct Cron Jobs configuration, and resolving any underlying issues. Document and analyze recurring failures to implement long-term solutions. Refer to the official Magento documentation for more information on reindexing in Magento 2.
