Macro Definition Documentation

#define INNOBASE_WAKE_INTERVAL 32

The following counter is used to convey information to InnoDB

about server activity: in selects it is not sensible to call srv_active_wake_master_thread after each fetch or search, we only do it every INNOBASE_WAKE_INTERVAL'th step.

Enumerator:

QRY_NON	None/Sentinel
QRY_INS	Insert operation
QRY_UPD	Update operation
QRY_SEL	Select operation

Definition at line 81 of file api0api.cc.

enum ib_tuple_type_t
