It can be used to test the running status of servers in static databases or active databases, and can be used to simulate heavy loads on servers or network systems to test their resistance, it can also be used to analyze all running conditions of different load types. It also provides a replaceable interface for customizing data display, test s
Preface:
It has been three months since the publication of the [Layer 2] in the blog series of "men are down to Layer 3, according to the previous visits and comments, many of my friends still like practical blog posts. After all, we are all called "siege lions", so we should check whether the "siege lions" are qualified and whether we can "build a house" instead of building a house. Let's start with chicke
, product managers think that they can come up with 7 decisions a day without consulting. If they discuss with engineers, they can make a decision.
Engineers have a good quality awareness, so they have also created a happy day. The specific way is to find out the day of the working day. engineers work together to tackle a specific problem and write their ownCodeTo see who can solve the problem best. With the increasing business-oriented development of Douban, the number of engineers is also inc

A hash table is a pair that is no longer restricted to the use of digital addressing in the hash tables, and can be addressed with any type of data type.
Creating a hash tableBefore using @ () to create an array, now use @{} to create a hash table, using the key of the hash table to access the corresponding value.

siege Lions invented the storage cluster, so that a user's data can be allocated on multiple servers to store , but in the user that seems to be just a 1G of continuous space, then there is no need to set up a contingency space on each server, or even full of the previous server full, Plug in the data down one server. This ensures that the maximum utilization of server space, if a moment the administrator found that users are crazy upload data (in a
