Hi Team,
I have speakers and session as two different entities
the relation looks like
type Speaker {
id: String!
bio: String
name: String
sessions(title:String): [Session]
}
Now I want to fetch all the details of speaker and fetch the sessions of that speaker.
Currently the execution is sequential for each speaker id the session resolver is involved.
In real time if I have thousands of speaker records, thousands times the session resolver will involved . For example if the session resolver datasource is a database the performance will be impacted because the database will called equal to the number of speakers from the parent call. Is it possible to extract the all speakers one shot and push it child i.e session resolver ?
