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.

From this Stored Procedure tab, you can configure the databases for which stored procedure query responses should be cached and specify the patterns or rules that trigger data cache. Refer to Query Caching as a guide on when to keep ON or turn OFF this feature (ON by default). 

  1. On the ScaleArc dashboard, navigate to CLUSTERS > Settings column > Transparent Cache.

  2. Click on the Stored Procedure tab.


List stored procedures

  1. Click on the gear icon against the database you want to enable for stored procedure query caching.


  2. Follow the table to configure the stored procedure feature. Refer to Query patterns for a description of the remaining widgets on the screen.
