Krzysztof Nienartowicz created OPENJPA-2760:
-----------------------------------------------
Summary: Cache classes, esp DataCacheManagerImpl should be less
private
Key: OPENJPA-2760
URL: https://issues.apache.org/jira/browse/OPENJPA-2760
Project: OpenJPA
Issue Type: Improvement
Components: datacache
Reporter: Krzysztof Nienartowicz
We are trying to circumvent N+1 query problem by making cache more 1-m
relations aware. We have a working solution, but it would be much more elegant
if the datacache classes were much more expandable, i.e. is
DataCacheManagerImpl very private and this with a specialized code in the
AbstractDataCache that is supposed to be the base for cache expandability does
not help (i.e. we have there:
...
*if*(manager *instanceof* DataCacheManagerImpl){
...
Could you please refactor so all cache fields to be protected, esp in this
class? We can send a patch as well.
Once we have a working solution for N+1 problem we can share it, it looks
promising, but we are still unsure about certain corner cases.
Thanks
