Error: Magento 2 Reindexing One or More Indexes are Invalid Make Sure Your Magento Cron Job is Running
This error message is displayed on your Magento admin panel when your data is not indexed properly. Troubleshooting this error is simple and easy. The error message itself gives you a hint on how to address this issue. The only solution is to reindex your Magento data.
Indexing is how Magento transforms your data such as categories, products, catalogs, and so on. The indexing is performed to improve the performance of your storefront. The transformed data must be updated or reindexed as data changes. Magento stores your merchant data in many database tables. Magento accumulates data into special tables using indexers to optimize storefront performance.
The data reindexing can be easily performed from your Magento admin panel. Follow the below steps to reindex the data.
1) Login to your admin panel as Administrator.
2) Navigate to System > Index Management.
3) To update one index only, click the Reindex Data link in the Action column on the right. To update more than one indexer at a time, select the check box next to its name. From the Action list, click Reindex Data and then click Submit.
4) Please wait until the re-indexing is completed. Now your indexes are up-to-date.
Reindexing Mass Data
