But this is still a good question. For all the others bins you could apply a different policy. But this is not always true, depends a lot on your Drupal cache usages I said before cache engines can be faster in both write and read operations. Drupal use a lot of caches at different levels but all of them are by default stored in the database.
But this is still a good question. Keep in mind that you should never make a server swap. There is no magic rules, the best tool will depend on your cache usage and on used modules.

And for each bin you can specify which storage backend will be used. And of course some existing modules could help you doing that. So by definition it’s quite hard to perform some fine tunning on the MySQL server if this table drual not removed. The first question is drupzl should I put each separate cache bin or each cache table for short? Today it’s still a sandboxed module, no official release.
We’ve just been removing write and read requests from MySQL.
We coudl also talk about the lock API in Drupal lock. The memcache module, for example.
More on this module when released like how to manage session locks, how to configure the cache backend for sessions, etc. Sorti finle CMS Drupal 8 a basculé dans un rrupal cycle de versions tous les 6 mois.
