Configuring Stored Procedure Query Caching

The Transparent Cache feature makes it possible to configure the databases for which query responses need to be cached and specify the patterns or rules that trigger data cache. Once these rules have been set up, frequently used queries will be offloaded to ScaleArc to reduce database load and improve stored procedure response times.

This article describes the procedure for configuring the stored procedure query caching feature. Ensure that Query Caching is enabled before proceeding with the following steps: 

1. On the ScaleArc dashboard, navigate to CLUSTERS > Settings >Transparent Cache.
   
    
    
2. Click on the Stored Procedure tab.
   
   
   
   

List stored procedures

1. Click on the Gear icon against the database to be configured.
   
   
   
   

2. Follow the table to configure the stored procedure query caching. Refer to Query patterns under Cache Rules for a description of the remaining widgets on the screen.
