About buffered queries and no buffer queriesThere are two types of queries for MySQL clients:buffered queries: will receive the results of the query and store them in the client's cache, and the request to obtain row records is only obtained locally.(1) Advantage: You can move the "current row" pointer freely in the result set, which is easy to find because the result is in the presence of the client.(2) Disadvantage: Additional memory is required to

Brief introduction Another very good feature of SQL Server 2014 is that SSD can be virtualized as part of memory for use by SQL Server data page buffers. By using SSD to extend Buffer-pool, a large number of random IOPS can be hosted by SSD, which reduces the random IOPS and page-out for data pages. SSD as Buffer Pool SSD is a solid-state drive, unlike a traditional disk with a magnetic head moving part,

Implement a dual-Buffer Queue and a dual-Buffer Queue In the producer-consumer mode, we often use a queue, which has mutex and competitive operations when multiple threads share access, meaning that each access is locked. How can we better reduce the number of lock competitions? The dual-Buffer Queue to be introduced today is a good choice. The dual-
