Logging GC usage is not intrusive, and so it is reasonable to enable GC logging in production by default in the event you ever need to analyze memory problems or tune the garbage collector.
记录GC使用情况并不具有干扰性，因此如果需要分析内存问题或者调优垃圾收集器，在生产环境中默认启用gc日志是值得的。
And since db2pd works directly with memory, it can retrieve data quickly and in a very non-intrusive manner.
而且因为db 2 pd直接处理内存，它可以迅速并以非侵入性的方式检索数据。
Iterating an Intrusive container needs less memory accesses than the semantically equivalent container of Pointers: iteration is faster.
介入式容器的迭代比相同语义的指针容器需要更少的内存访问：迭代可以更快。
Operating with intrusive containers doesn't invoke any memory management at all. The time and size overhead associated with dynamic memory can be minimized.
介入式容器的操作根本不会引发任何内存管理。动态内存分配所带来的时间和空间开销可以被最小化。
Memory management usually is not a predictable operation so complexity guarantees from non-intrusive containers are looser than the guarantees offered by intrusive containers.
内存管理通常都不是一个可预见的操作，因此非介入式容器的复杂度保证要比介入式容器所提供的保证宽松。
Similar to an intrusive container but a semi-intrusive container needs additional memory (e. g. an auxiliary array) to work.
类似于介入式容器，但需要额外的内存（如一个辅助数组）才能工作。
