Benedict commented on CASSANDRA-8897:
-------------------------------------
bq. The "visits" seem to work for standard commands but not for user profiles.
It doesn't work for the standard/legacy modes - it isn't possible to use it,
since there's no clustering. You still need to provide it on the command line
for the user profile mode.
bq. Anyway, the test result is here.
It looks like in the code we haven't switched RAR to requesting DBB, but we
have disabled the BufferPool's management of heap buffers (with the intention
that we switch them all to off heap / direct). So we should probably re-run
with that updated.
> Remove FileCacheService, instead pooling the buffers

> After CASSANDRA-8893, a RAR will be a very lightweight object and will not
> need caching, so we can eliminate this cache entirely. Instead we should have
> a pool of buffers that are page-aligned.
