this separation ing at the application layer, you can use the database reverse proxy to automatically complete read/write separation.
Vertical partitioning
Data Tables that do not require joint queries can be distributed to different database servers, which are called vertical partitions. Of course, each partition can also use read/write splitting.
Horizontal partitioning
Splitting records from the same table to different tables or even servers is called horizontal partitioning. T
Objects are very similar to arrays, which are indexed to access and modify data, and objects to access and modify data through properties.var cat = {"Name": "Whiskers","Legs": 4,"Tails": 1,"Enemies": ["Water", "Dogs"]};var myObj = {"Space Name": "Kirk","More Space": "Spock"};myobj["Space Name"]; Kirkmyobj[' more Space ']; SpockAnother way of using the bracket operator is to use a variable to access a property. This is useful when you need to traverse

JS uses the event-driven architecture, which means that everything that is done on it, each separate invocation and operation, is a series of asynchronous callbacks. This allows node. js to run on one thread, which is different from other web technologies, and each client's request will generate a new thread to handle. This is where the nature of non-blocking I/O is. Support Object Database It is very common to use object databases such as Mong
