[in depth understanding of tcapulusdb technology] new models of tcapulusdb

Take batch new models as an example , Click batch new models , Fill in the following information （ There are many messages , Please refer to the error information to modify the relevant parameters ）

Be careful ：

​ 1、 The model name is not case sensitive

​ 2、 Model sort ： The order of models is the priority of machines , Add table review Auto audit when ,shard、proxy Can only be assigned to one model , It is preferentially allocated to machines that can meet the requirements of adding table resources with a smaller sorting value

​ 3、tcapsvr、tcaproxy Calculation process of the number of available units ：
​ ① Calculate according to memory capacity ：mNum = Memory capacity / Storage unit size
​ ② Calculated based on disk capacity ：dNum = Disk capacity size /( Storage unit size * Disk memory ratio )
​ ③ The number of available units is taken as **mNum,dNum,224（tcapsvr、tcaproxy Maximum number of available units ）** The smallest of the three
​ notes ： Under each cell model , Storage unit size ： Standard region ：1GB; Multi cell ：0.5GB; Low cost area ：0.25GB;

​ 4、 In cluster maintenance, when the machine configuration on the shelf mode is formal, only the machines in the formal environment can be on the shelf , For testing, the machine can be put on the shelf formally or on the shelf for testing

​ 5、 The number of available units of the tested models is 512 individual
