性能优化之Block Nested-Loop Join(BNL) 一介绍相信许多开发/DBA在使用MySQL的过程中,对于MySQL处理多表关联的方式或者说性能一直不太满意。对于开发提交的含有join的查询,一般比较抗拒,从而建议将join拆分,避免join可能带来的性能问题,同时也增加了程序和DB的网络交互。MySQL本身只支持一种表间关联方式,就是嵌套循环...

异常类型:java.lang.IllegalStateException 是一个运行时异常,表明程序在不应该的状态下尝试执行某个操作。 异常信息:“Failed to create a child event loop” 表示程序在尝试创建一个子事件循环时失败了。 2. 搜索异常原因 可能原因: 线程使用不当:程序中可能使用了过多的线程,导致无法再创建新的线程用于事件循...
If you need loops depending on current value in the loop above (parent loop): for(inti=0;i<2;i++) {for(intj=i;j<3;j++) {for(intk=j+1;k<4;k++) {for(intl=1;l<k+2;l++) {target.append(Arrays.asList(i,j,k,l)); } } } } ...
The other for loop that loops over the names is moved inside theMappedFieldclass, so only this class needs to understand the internals of how these names are stored. Let’s step through one way of performing this refactoring. There’s more than one approach of course, this is just one ex...
