innodb_buffer_pool_size and relationship to max_heap_table_size (no replies)

Hi,

Currently I'm trying to tune innodb_buffer_pool_size.
That in itself seems ok based on the guidelines provided.

In the InnoDB engine, is max_heap_table_size taken into account?

I have some big tables ( ie. ranging from 1G to 6G currently)

If the max_heap_table_size is low ( say 64M for example), will the vast majority of these tables require intensive disk IO?

I have a powerful server with ~100G physical RAM.
So looking at a pool allocation of about 85G.


The over all table data size is currently about 30G but expected to grow somewhat.

Can I set the max_heap_table_size to be ~6G?
In theory this should allow all these large tables to be cached - is this correct?

Is there anything else to be considered?

Any negatives in relation to this configuration?

Appreciate any thoughts.
Thanks.
