Data Fields | |
| os_fast_mutex_t * | mutex |
| ulint | pad |
| ulint | success |
| ulint | failure |
| ulint | n_rounds |
| volatile os_once::state_t | mutex_created |
Detailed Description
Data structure to hold information about how much space in
an uncompressed page should be left as padding to avoid compression failures. This estimate is based on a self-adapting heuristic.
