The information_schema_stats_expiry system variable defines the period of time before cached table statistics expire. If there are no cached statistics or statistics have expired, statistics are retrieved from storage engines when querying table ...

InnoDB provides a configurable locking mechanism that can significantly improve scalability and performance of SQL statements that add rows to tables with AUTO_INCREMENT columns. To use the AUTO_INCREMENT mechanism with an InnoDB table, an ...

Most often, the internal optimizations described in InnoDB Data Storage and Compression ensure that the system runs well with compressed data. However, because the efficiency of compression depends on the nature of your data, you can make decisions ...

Compressed tables can be created in file-per-table tablespaces or in general tablespaces. The system tablespace (space 0, the .ibdata files) can contain user-created tables, but it also contains internal system data, which is never compressed.
https://dev.mysql.com/doc/refman/8.4/en/innodb-file-per-table-tablespaces.html
A file-per-table tablespace contains data and indexes for a single InnoDB table, and is stored on the file system in a single data file. File-per-table tablespace characteristics are described under the following topics in this section: ...

INNODB_FT_BEING_DELETED: Provides a snapshot of the INNODB_FT_DELETED table; it is used only during an OPTIMIZE TABLE maintenance operation. When OPTIMIZE TABLE is run, the INNODB_FT_BEING_DELETED table is emptied, and DOC_ID values are removed from ...
https://dev.mysql.com/doc/refman/8.4/en/innodb-limits.html
This section describes limits for InnoDB tables, indexes, tablespaces, and other aspects of the InnoDB storage engine. The index key prefix length limit is 3072 bytes for InnoDB tables that use DYNAMIC or COMPRESSED row format. The index key prefix ...

The persistent optimizer statistics feature improves plan stability by storing statistics to disk and making them persistent across server restarts so that the optimizer is more likely to make consistent choices each time for a given query.
