  • Scalability of Roo application architecture with JPA entities

    Hi,

    what are the best practises for Roo generated applications which shall scale to a really big number of concurrent requests? Is this ever possible?

    Problems I see:
    * OpenEntityManagerInViewFilter -> looong running transactions
    * populating lookup lists, regardless of the size of these lists (OK, somewhat manageable via populateMethods)
    * generated finders often load big object trees, often with 1:n selects due to lazy loading
    * other?

    How could I solve these problems without discarding Roo (I relly like it)?

    Thank you
Working...
