machine, is a big challenge in a distributed environment.
So distributed coordination is much more difficult than scheduling multiple processes on the same machine, and if you develop a separate coordinator for each distributed application. On the one hand, it is wasteful to write the coordination program repeatedly, and it is difficult to form a universal and good scalability coordinator. On the other hand, the coordination program overhead is relatively large, it will affect the original perf

I will always remember the night when I watched sports news as usual. My wife took a bath and said to me, "How come I got a black mole on my feet ?"
I am a person without medical knowledge. I think women like to make a fuss and ignore her.

basically no one cares. Even more amazing, we spent a lot of time studying the ingredients in the headers-or you're thinking, maybe I know the ingredients in the headers, I admit it will help, but do you know how much opportunity cost we have to pay in the middle? Will the problem be escalated accidentally, from a simple level of "familiar with projects" to a high level of "can I show my competency during the trial period, in the end, I don't know how I died.

Fuck your aging. Despite this, Cao remains a solid empire after his death and is guarded by many heroes.
Like the expansion of the empire, Cao's private life also has a strong aggressive style. The Cao family has been robbing others of his wife.
Traditionally, this may come from some features of the Northern barbarian. Cao forced the night with the wife of a surrender

In distributedAlgorithmA very important algorithm in the field is paxos. How important is it, as mentioned in Google's chubby [1 ].
All working protocols for asynchronous consensus we have so far encountered have paxos at their core.
More details about paxos algorithms are provided in Wikipedia. The Chinese version introduces the choose value rule [2]. The English version introduces the paxos 3 phase commit process [3]. the Chinese versi

There is a master machine throughout the system that dynamically adjusts the distribution of the tablet on each machine based on factors such as the size of the tablet, the load, and the load capacity of the machine.The master server has the metadata table for the tablet's attribution . When the amount of data is very large, the metadata table will actually become very large, so the attribution table is actually cut into a separate tablet on the tablet server

Encapsulation literally means packaging. Professional point is data hiding, refers to the use of abstract data and data-based operations to encapsulate, so that it constitutes an indivisible independent entity, the data is protected in the abstract data type inside, as far as possible to hide the details, only some external interface and external contact. Other objects of the system can communicate and interact with this encapsulated object only through an authorized method that wraps outside th
