Description
Hi,
While reviewing the Aria System Variables, for pagecache_reads the count references pages read from disk, whereas pagecache_writes references blocks written to disk. Is this accurate? I would have expected them both to reference the same structure when communicating with the disk subsystem.
Aria_pagecache_reads
Description: The number of Aria page cache read requests that caused a page to be read from the disk.
...
Aria_pagecache_writes
Description: The number of blocks written to disk from the Aria page cache.
I'm sorry if I selected the incorrect project or if there's an alternate way to solicit changes to the Documentation, it wasn't clear to me where to make DOC specific reports.
