spring - Minimizing the impact of session data on memory usage for a webapp -

i looking advice on how minimize impact of session info on memory web application.

most of services webapp provide require user signed in. however, i don't want store session of objects' data (website fellow member entities corresponding relationships).

on other hand, if store website fellow member id session, have fetch info database each time need farther information.

i grateful if provide advice or point me best practices.

for information, utilize java/jpa/mysql , spring framework (but guess that's not relevant).
