WL#7868: InnoDB: Improvements around flushing for proper performance
Browse files Browse the repository at this point in the history 
1: Implementing improvements to the adaptive flushing algorithm

1-a: should consider the distribution about the oldest LSN of the pages
in the
end of the flush_list

1-b: should consider flushing balance for each buffer pool instances

2: Setting a thread priority for the page_cleaner (if the platform
allows and
authorized to set)

3: Proper flush waiting when the max modified LSN age is around
max_modified_age_sync

3': should block the checkpoint LSN overwritten
