Go processes data efficiently through streaming API s such as Map/Filter/ForEach
What is stream processing
If you have Java experience, you will be full of praise for java8 Stream, which greatly improves your ability to process collection type data.
int sum = widgets.stream()
.filter(w -> w.getColor() == RED)
.mapToInt(w -> w.getWeight())
.sum();
Stream enables us to support ...

The average delay of the service is basically about 30ms. One of the very big prerequisites is that we make extensive use of MapReduce technology, so that even if our service calls many services, it often depends only on the duration of the slowest request.
For your existing services, you do not need to optimi ...

The most common protection mechanism is the current limiting mech ...
