https://dev.mysql.com/innodb-auto-increment-handling.html
The current maximum auto-increment counter value is written to the redo log each time it changes and is saved to an engine-private system table on each checkpoint. On a server restart during crash recovery, InnoDB initializes the in-memory ...

https://dev.mysql.com/innodb-buffer-pool-stats-table.html
Pages made “young” take longer to age out of the buffer pool, while pages made “not young” are moved much closer to the point of eviction. The INNODB_BUFFER_POOL_STATS table provides much of the same buffer pool information provided in SHOW ...
https://dev.mysql.com/innodb-compression-tuning.html
On the other hand, tables containing mostly binary data (integers or floating point numbers) or data that is previously compressed (for example JPEG or PNG images) may not generally compress well, significantly or at all. Most often, the internal ...
https://dev.mysql.com/innodb-configuring-io-capacity.html
The innodb_flush_sync variable, which is enabled by default, causes the innodb_io_capacity setting to be ignored during bursts of I/O activity that occur at checkpoints. When configuring innodb_io_capacity_max, twice the innodb_io_capacity is often ... The InnoDB master thread and other threads perform various tasks in the background, most of which are I/O related, such as flushing dirty pages from the buffer pool and writing changes from the change buffer to the appropriate secondary ...
