Auto update statistics asynchronously 2005




















You must understand the consequence of enabling this. You should not enable it directly on the production database. If you want to use the asynchronous statistics update, test it thoroughly in a development environment with a workload similar to production.

Using this option, Azure SQL Server waits for the background request to acquire schema modification lock. It persists the updated statistics using the low-priority queue. It allows requests to compile queries with current statistics.

Suppose the background request cannot acquire the lock. It gets a timeout that results in asynchronous statistics task abortion. In this case, statistics need to be manually updated, or it needs to wait for another update statistics trigger. In this article, we explored SQL Server statistics configuration for automatic stats update asynchronously. The default configuration for async stats is disabled. Therefore, each environment requirement is different; therefore, we cannot have general guidance for asynchronous statistics updates.

However, it is not required in most OLTP environments. You must not enable it until you have special requirements. Always test the configuration on a lower environment, understand the impact and plan it on the production database. Author Recent Posts. Rajendra Gupta.
