1. How is the Book of Life and Death technically realized? What is the unique marking of the vast number of living beings in the book of life and death? What kind of a database is the netherworld database?
First of all, there must be a database in hell, the amount of data is too large every living being must have a record, and it must be a real-time record, to analyze the data. Imagine all kinds of living beings, everything has a spirit, big and small, even the mole cricket moth is life, from a single cell to the modern society of the data should be how big. The database then each living being would have to be uniquely labeled.
Secondly, the query efficiency must be high query efficiency is low, Yama still have to point a cigarette and wait for half a day results, there are often higher officials over to check the data, the Jade Emperor ah, RuLai ah, even if it is Ananda, Gaya Ye also can not afford to mess with the people, the user is not satisfied with the KPI can not be poor performance, Yama's official position is not stable. Business is so large, every day at least insert hundreds of millions of new records, delete hundreds of millions of records, all the good and evil state data to be recorded in real time, think about how many good and evil sensors to be connected to the channel conflict is certainly difficult to solve, good and bad things with WIFI or ZIGBEE transmission is not clear, maybe a rice will launch a family of good and evil intelligent data processing center.
After the death of living beings, we have to quickly analyze the big data and determine how many layers of hell the dead should enter. Data analysis slow Naihe Bridge have to queue, the user bad reviews have wood! Data granularity is very, very fine, the time of death of three or five can not be worse, how many times in hell to hit the iron rod should be calculated accurately, and there will be a lot of abnormalities, sometimes to roll back, may accidentally operate the wrong; sometimes to disaster recovery, such as the monkey monkey mess caused by the catastrophic loss of data; such as the problem of user complaints, why the monkey should be short-lived? This kind of question only Sun Monkey can ask, not only can ask but also directly to the door to blame, the hell of security work really need to be strengthened.
On the other hand, the abnormal users like Wukong, Sa can't wait to delete them, can they? (Do not understand Sa IT people please face the wall, admin is also considered sa)
Again, must be able to cope with instantaneous concurrent peak data war came, thousands of people killed in action; plague, thousands of people died; extermination of rats, tens of thousands of hundreds of thousands of rats are finished; airplanes spread pesticides, how much practice is not enough to batch the end of the small elves. There are living beings who die must be registered and move the process forward, this is a typical mobile application, countless hook ghosts in a short period of time to fly to the scene, regardless of whether it is scanning the QR code or near-field communication technology NFC, anyway, countless ghosts at the same time with a mobile client to upload data to the Hell-DBMS system, the App must be friendly, the background must be able to hold the top, can not learn 12307-1 always fall off the chain. 12307-1 dropped the chain can still scold it: "Go to Hell!", Hell-DBMS can be how to scold is good. So:
At the critical moment, the server can not be stuck, the database can not fall, life and death thin must be updated in real time.
Lastly, there must be big data analytics and predictive technology in the netherworld, there is Shimei listening, can be "listened to", get the past data and future data, which is obviously the combination of big data and cloud masterpiece. Why listen? Because the netherworld database has been the data voice, with directed beams directly to the ears of the Shimei listening, electromagnetic listening has no effect, almost impossible to leak. Directional beam technology in the increased power can be used at the same time in the netherworld square dancing certain undead people.
