I did before mongo Action object , But it's not practical enough （ Reuse ）, So this time it is rewritten as a micro service , As part of the standard microservice system .

There are some benefits to using interface services ：

• 1 It is flexible to modify
• 2 Can write corresponding documents , It will be more convenient to reuse
• 3 It can be on the Internet （ Computing network ） Share on

1 mongo Stored content

Storage can json data

mongo It has many functions , Generally speaking, it can be used ：

• 1 Log data (log)：mongo The performance is fairly good , There is no problem storing logs .
• 2 Master data (master)： Of course, you can also change the log data into primary data （ The only merger in time and space ）.
• 3 Quasi static data (static)： For example, some data may be loaded when a service starts , Such visits are not frequent , Data with little change .
• 4 Metadata (meta)： A summary of some tasks , Or some information generated by the algorithm in the process .

It is agreed that each library for different purposes should be suffixed with the table name , for example db_meta Indicates that this is a storage db Metadata Library .

stay DataMill There is also in the concept DM and DNWS, There are also parts that store data . But the main storage is can pkl data , Used in python Object persistence . Generally speaking , Each data can be relatively large (<=2GB).
