Label:in MySQL data table, use MyISAM engine faster, storage space is smaller; InnoDB engine insertion speed is slightly faster, the key is to support transactions. Is it good to use MyISAM or InnoDB in practical applications? Specific problem specific analysis, determined by your system characteristics, If the use of MyISAM, get performance improvement, but will lose the support of the transaction, the va

MongoDB 3.2 WiredTiger storage engine performance test MongoDB 3.2 was recently released. It uses WiredTiger as its default storage engine. Over the past five years, MongoDB has developed rapidly from its birth to its popularity. MongoDB 3.0 began to support the "pluggable storage engine" function, so it is reasonable

The previous article briefly introduced the more common unit test framework in the Ocunit and Ghunit two iOS development, and this article further introduced another weapon in unit testing-matching engine (Matcher Engine). The matching engine can replace the assertion method, with the unit

tables that use additional InnoDB features (such as foreign keys. In addition, the row lock of the InnoDB table is not absolute. If MySQL cannot determine the scope to be scanned when an SQL statement is executed, the InnoDB table will also lock the entire table, for example, update table set num = 1 where name like "% aaa %" To sum up, none of the tables is omnipotent. Only by selecting the appropriate table type for the business type can we maximize the performance advantages of MySQL. ===

In terms of service coupling, a search engine can be divided into two parts: online and offline. The two parts are associated through index.Online can be divided into core engines and online applications, while offline contains data crawling and offline processing processes.The search engine online test can be divided into the following steps: Unit test:It is

When creating an index, the MySQLMyIsam storage engine has a strict length limit. The maximum length of all index keys cannot exceed 1000, and it is not the sum of actual data lengths, the sum of the index key field definition length. Let's take a simple test and record it.
