You can optimize SQL data services to improve performance when end users run SQL queries against them using third-party client tools. If an SQL data service uses a virtual table mapping, you can optimize the sources, transformations, and the mapping.
Use the following optimization techniques to optimize an SQL data service:
Optimize third-party client tools.
Configure the SQL data service optimizer level.
Configure SQL data service properties for concurrency and memory for a Data Integration process.
Configure data object caching for the SQL data service.
Configure result set caching for the SQL data service.
Configure constraints for virtual tables in the SQL data service.
