Drools-规则数量和磁导空间之间有直接关系吗？ [英] Drools - Is there a direct correlation between number of rules and permgen space?

问题描述

我运行了100条规则的流口水决策表，效果很好。但是，一旦我将规则数量增加到1000，我就开始出现permgen空间错误。我必须将permgen的进程增加到256MB，才能容纳3000条规则。我担心的是，随着我不断添加规则，我可能需要越来越多的permgen。

I ran drools decision table with 100 rules and it worked fine. But as soon as I increased the number of rules to 1000, I started getting permgen space error. I had to increase permgen to 256MB for my process to accommodate the 3000 rules. My concern is as I keep adding the rules, I might need more and more permgen.

由于此问题，我正在考虑不使用流口水并开发自定义解决方案。

I am thinking of not using drools and develop a custom solution due to this issue.

这是正确的观察结果还是我做错了什么，导致电烫发电的空间需求增加了？

Is this correct observation or am I doing something wrong causing the perm gen space requirement to increase
