24.32 INFORMATION_SCHEMA InnoDB Tables

This section provides table definitions for InnoDB INFORMATION_SCHEMA tables. For related information and examples, see Section 14.16, “InnoDB INFORMATION_SCHEMA Tables”.

InnoDB INFORMATION_SCHEMA tables can be used to monitor ongoing InnoDB activity, to detect inefficiencies before they turn into issues, or to troubleshoot performance and capacity issues. As your database becomes bigger and busier, running up against the limits of your hardware capacity, you monitor and tune these aspects to keep the database running smoothly.
