I implemented springboot application using hikari CP for database connection pooling. And now I need to deploy the application to the Jboss EAP server which has datasources configuration with connection pool. what happen if i deploy the application on the WAS? would Hikari CP manages connections based on the WAS's datasource connection pool? or would size of connection pool be just added? (hikariCP pool size + jboss datasource pool size) Is it common to use both application level connection pool and WAS connection pool at the same time? Or should I remove hikari CP from application before deploy it to jboss?
as i check in the APM tool connection size seems be added (hikariCP pool size + jboss datasource pool size). but i'm not sure is it normal. i expected hikari CP would work based on the WAS connection pool size.
