Add multiple fields to register dataFetcher #2998

This API can't meet my needs. I need to bind multiple fields. When querying bound fields, I only call DataFetcher#get once

For implementation spring-projects/spring-graphql#519 This function

Do you consider adding this function?
I think this function can reduce the number of queries to the actual database in some special cases.

Typically you would use sub selection read ahead

See https://www.graphql-java.com/blog/deep-dive-data-fetcher-results

I understand that graphql is more suitable as a data gateway. It is necessary to use this function because it will involve migrating data sources in the application iteration process.
I plan to use Reactive and cache to obtain data, and use simple code to aggregate a large number of fields to reduce development difficulty.

Did you have a look at sub selection read ahead. This allows you to see what sub fields have been asked for and then allows you to prefetch based on the asked for fields

Thank you for your example. I have seen the example you mentioned. That example can meet my needs.
I hope to get a simpler api, which is more convenient for developing functions.
