Do you know that there are two limits about dirty (modified but not flushed to disk) blocks of InnoDB buffer pool? One is the limit of “amountâ€. The other is the limit of “ageâ€. — limit of “amount†— As you know, buffer pool of InnoDB works as write-back cache of its datafiles.

InnoDB Flushing: Theory and Solutions
I mentioned problems with InnoDB flushing in a previous post. Before getting to ideas on a solution, let’s define some terms and take a look into theory. The two most important parameters for InnoDB performance are innodb_buffer_pool_size and innodb_log_file_size. InnoDB works with data in memory, and all changes to data are performed in memory. In order to survive a crash or system failure, InnoD

Typically, this type of recovery is performed after restoring a full backup that brings the server to its state as of the time the backup was made. (The full backup can be made in several ways, such as those listed in Section 9.2, “Database Backup Methodsâ€.) Point-in-time recovery then brings the server up to da
