Index, it can be said that database-related optimization, especially in query optimization, one of the most common optimization means, although so, but the index is not a solution to query optimization of the Bible, can not only find query run fast enough to put the conditions in the WHERE clause all in the index. Everything is appropriate and can be stopped, too far, together to see what it is. Index of the Profit place The index can improve the efficiency of data retrieval, reduce the IO cos

In the previous article (database indexing Principle 1), we elaborated on the basic concepts and data query principles of indexes, we know that when creating an index, we must make a balance between "speeding up the query speed" and "Reducing the modification speed". If there is a loss, this will take a long time. So how does SQLS consume resources when maintaining indexes? In what ways should indexes be managed and optimized? Here are seven answers t

("Full table Scan"), read the document based on location information, and compare the age field to 18. Of course, if there are only 4 documents, the cost of full-table scanning is not big, but if the collection of documents to millions, or even tens of billions of times, the collection of full table scan cost is very large, a query of 10 seconds or even a few minutes is possible. If you want to speed up db.person.find( {age: 18} ） , consider indexing

In particular, when the amount of data is very large and the query involves more than one table, using an index can often speed up the query by tens of thousands of times.For example, there are 3 unindexed tables T1,T2,T3, each containing
