Scheduled Grid Updates

The Grid Settings configuration schedules updates to the following order management grids, and reindexes the data as scheduled by Cron:

The benefits of scheduling these tasks is to avoid the locks that occur when data is saved, and to reduce processing time. When enabled, any updates take place only during the scheduled cron job. For best results, Cron should be configured to run once every minute.

To enable scheduled grid updates and reindexing:

1. On the Admin sidebar, tap Stores. Then under Settings, choose Configuration.
2. In the panel on the left under Advanced, choose Developer.
3. Expand the Grid Settings section.
4. Set Asynchronous Indexing to “Enable.”
5. When complete, tap Save Config.
