Hello Johan.
Thank you for the reply.
I see. So it will depend on the key buffer size.

Hi Reindl.
Thanks for the reply.

None, as Reindl said. This is not a memory issue, it's a function of I/O
optimization. Records are stored
Also,

Hi !
I would like to ask question regarding to the MyISAM engine.
Is there any physical file that you have to be aware of its size
