InnoDB page cleaner keeps waking up on idle server

    XMLWordPrintable

    Details

      Description

      The purpose of the InnoDB page cleaner subsystem is to write out modified pages from the buffer pool to data files. When the innodb_max_dirty_pages_pct_lwm is not exceeded or innodb_adaptive_flushing=ON decides not to write out anything, the page cleaner should keep sleeping indefinitely until the state of the system changes: a dirty page is added to the buffer pool such that the page cleaner would no longer be idle.
