Matt Stump updated CASSANDRA-8160:
----------------------------------
Attachment: trunk-8160.txt
Attaching my functional patch. I've been trying to find time to do performance
testing to quantify gains if any, but haven't had time yet. Running into
cassandra-stress bugs when attempting to use a custom yaml on cstar-perf.
Haven't had time to run it down.

> We should have a CF level configuration with will result in posix_fadvise
> being called for sstables for that CF. It should be called on node startup
> and for new sstables. This should be configurable per CF to allow for some
> CFs to be prioritized above others. Not sure if we should use
> POSIX_FADV_SEQUENTIAL or POSIX_FADV_WILLNEED.
