Re: [castor-dev] JDO Performance Issue ... Again

[Low Heng Sin]

I've implemented the lazy/non-lazy loading of 1:n relation in separate query solution and would like to share it with anyone who is interested with it. Thomas, would u mind to share your plan solution with me so that I can digest how different is my solution and probably adjust it closer to what u have in mind.   thanks.   Regards, Low -----Original Message----- From: Thomas Yip [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 23, 2002 2:33 To: [EMAIL PROTECTED] Subject: Re: [castor-dev] JDO Performance Issue ... Again Hi Jan,     You’re right. It is a fundamental limitation. It can’t be fixed without a lot of work. It has been discussed in the mailing list a few times in the past.   We had plan for it. However, it becomes obvious that we are not going to have enough resource on execute it any time soon.         Thomas   -----Original Message----- >From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] >Sent: Monday, April 22, 2002 7:25 AM >To: [EMAIL PROTECTED] >Subject: Re: [castor-dev] JDO Performance Issue ...
