Well, you seem to be assuming:
1) read ahead is done unconditionally, with an equal claim to disk resources
2) read ahead is actually enabled (tuning recommendations are that it be
disabled, or at least drastically reduced, to my knowledge)
3) read ahead happens synchronously (even if you burn
Hi,
Even with memory mapped IO the kernel is going to do read ahead. It
seems like if the issue is reading to much from the device it isn't
going to help to use memory mapped files or smaller buffered reads.
Maybe helps by some percentage, but it's still going to read quite a
bit extra.

The biggest problem with pread was the issue of over reading (reading 64k
where 4k would suffice), which was significantly improved in 2.2 iirc. I
don't think the penalty is very significant anymore, and if you are
experiencing time to safe point issues it's very likely a worthwhile switch

Probably those without suffix were created by previous Cassandra version
(somewhere in 2.x series)

Hello,
In the data directory of my 3.0.9 installation, I have directories with both
suffixes and without:

The directories with and without suffixes are being updated and for those with
a suffix, the suffix matches the output of
