九大块:
buffer pool, parsed andoptimized SQL statements, data dictionarycache, log buffer, locks for eachtransaction, hash table forthe adaptive index, state andbuffers for each SQL query currently being executed, session foreach user, and stack for eachOS thread.
9大块通过4部分停止治理
A solution tothe memory management: 1. the bufferpool size is set separately; 2. log buffersize is set separately; 3. the commonpool size for all the other entries, except 8, is set separately.
也就是缓冲池,redo日志缓冲,一般池和8(会员session信息,可看做一部分)
redo日志缓冲由redo部分独自治理,bufferpool也就是缓冲池是一个复杂的部分,内容许多,一般池上面说了,除了8,和1,2.其余的都归它管。
MySQL是用C++开发的。
MySQL的官方网站http://www.mysql.com/上有源码下载,是C++的
