Migration of a batch job (Micronaut to Apache Camel)

Our project is to convert a Salesforce batch job written in Micronaut to Spring Boot Apache Camel using Java. Currently, the Micronaut batch job is performing a hardDelete operation on sObject records fetched. The desired outcome of converting this batch job is to make maintenance easier. Furthermore, during the conversion, we are looking to make use of Salesforce REST APIs and Bulk API 2.0 for querying, creating jobs.Also create and use custom salesforce dtos as needed If there are any other features or functionalities that are suggestedwe are open to exploring those as well.
