This section provides table definitions for INFORMATION_SCHEMA InnoDB tables. For related information and examples, see Section 15.15, “InnoDB INFORMATION_SCHEMA Tables”.

INFORMATION_SCHEMA InnoDB 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.
