don't I put the id elsewhere, but at the end? In mongodb, indexes are executed from left to right. Therefore, it is clear that the maximum data volume needs to be filtered from left to right. Obviously, the combination of type and sex filters more data volumes than IDs, because the busy query rate of IDS is much higher than the two combinations.Then add the time-based sorting and query: db. test. find ({type: 1, sex: 1, id: {$ gt: 0, $ lt: 1000000 }}). sort ({time:-1 }). explain (){"cursor" : "

Build Cabinet 02:
cabinet = CreateGroup (' Cabinet 02 ', 146, 445);//Create cabinet 02createNode (' images/normal. JSON ', Cabinet, (). S (' label ', ' data monitoring and Analysis system ') ;//create a node with a "normal" picture and set the text of this node as "Data monitoring analysis System"
Because the connection requires "source node" and "End Node", here the source node is the intermediate "Internal network switch", we create this node:
var line = CreateNode

1) game development, the engine layer is implemented in C + +, but sometimes in order to integrate the SDK, call Android native, it is inevitable to think--c++ layer how to call the Java layer?2) The Android layer calls the C + + library to complete some features that are also common. Development will inevitably think about how to use Java to invoke C + + problems.The most recent project requirement is that Java calls C + + code to accomplish some of the functionality.Case 1. How C + + calls the

Re-designed automatic verification and completion mechanisms;
The validation class is designed independently;
The automatic generation function is
