Does Spring For GraphQL supports schema type generation from existing Java POJO? Just like Graphql-SPQR library? I do not want to maintain schemas in 2 places in POJO and also in Schema file.

With Spring Data R2DBC Postgres, with a lot of data with these N+1 calls I saw too many open files error so I suppose the upper bound is the size of the connection pool permitted by the DBAs. Is there a way to limit the number of concurrent db calls?

You can use the DataLoader feature in GraphQL to prefetch the items that you need

[@ChrisB_Crisps]

Or a distributed db approach if you are going to use Graphql in a real world application that needs a db

Great content as usual from @starbuxman. But I wish he would invest in a better microphone. The sound on his videos and podcasts are pretty crap, and have been for a long time.
