Destroyed key cache still usable ?
You can assign a table’s index to a key cache of MSSQL even after you have destroyed it.
To minimize the use of I/O operation, MSSQL provides you with a cache mechanism to maintain a block of memory for frequently used or accessed tables.
You just have to set the size of that particular cache:
mysql> SET GLOBAL key_cache1.key1_buffer_size=256*512;
You can also destroy this cache by setting its size to ‘0’:
mysql> SET GLOBAL key_cache1.key1_buffer_size=0;
But when I tried to reuse this destroyed cache again, it worked fine. I don’t know how this could happen?
Please, make me understand this point.
