Hi. If one database is down, then automatically the spring boot application should fetch data from second database. Can I know how to configure this type of configuration

In your application.properties is it necessary to set custom data sources when working with two types of database? Trying to use mongodb and h2.

Hi Raman, I observed that both of the db config classes has 3methods. I am wondering why is it required to use the @primary annotation when you have already specified the bean names. Can we not inject those beans when required using the @Qualifier annotation so as it to help spring differentiate ? Would to hear your thoughts on this

Hello Ramanpreet, i have some doubt, how to link a specific database configuration to a specific Repository because if we specify same basepackage for both config how we will get to know which db is providing data(if same type of database is used), so can you explain how can we map configuration with the Repository.
