We have a scenario where we want to turn off immediate retires and have only delayretries turned on for a specific type of exception, and have the oob immediate retires and delayed retries for other type of exceptions, is this customizable ?
Yes you can achieve that by specifying a policy. This documentation page should help
In the following example, for exceptions of type MyOtherBusinessException the default Delayed Retries time increase will be always five seconds, in all other cases the Default Recoverability Policy will be applied
