Jonathan Ellis commented on CASSANDRA-8160:
-------------------------------------------
Populate-on-open makes sense to me. I'm less sold on populate-on-write. Our
history of trying to outsmart the page cache is not a happy one.

>
> 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.
