Improvements
-
Server variables Add a new status variable
Mroonga_memory_map_size.We can get the total memory map size in bytes of Mroonga as below.
mysql> SHOW STATUS LIKE 'Mroonga_memory_map_size'; +-------------------------+----------+ | Variable_name | Value | +-------------------------+----------+ | Mroonga_memory_map_size | 83406848 | +-------------------------+----------+ 1 row in set (0.00 sec)In Windows, If Mroonga uses up physical memory and swap area, Mroonga can't more mapping memory than that. Therefore, we can control properly memory map size by monitoring this value even if the environment does have not enough memory.
