For databases, it is nothing more than adding, deleting, modifying, and querying. Generally, in project applications, READ operations account for more than 50% of the operations, and customers are usually sensitive to this, it is not easy to handle in terms of efficiency, and it is often to be put aside by future generations! So now we need indexes to play a role. Next, let's take a look at the sensory differences brought by indexes. Then, let's talk about the

The Find () function in the MongoDB returns a cursor that enables the client to effectively control the query results by setting some settings on the cursor, such as restricting the number of results obtained by the query, skipping partial results, or pressing any key to the result set. We used to operate in the shell, using the Find () function directly, without using its return value, such as: > for (var i=0 i We first populate the collection wit
