ChatGPT: The InnoDB buffer pool is used by MySQL to cache frequently accessed data in memory. If we expand the cache concept more, the buffer pool could be even less if the working set (hot data) is smaller. Questions Q: I have a MySQL server with 500 GB of RAM; my data set is 100 GB. How large my InnoDB buffer pool needs to be?
