Edward Capriolo commented on CASSANDRA-2325:
--------------------------------------------
@Jonathon,
We could do this
{noformat}
public void invalidateKeyCache()
{
keyCache.clear();
if (!keyCache.getCachePath().delete()){
logger.error("KeyCache "+columnFamily+" delete failed.");
}
}
{noformat}
But I am wondering how that effects systems like the Memcache row caching that
are not physical files. I was just assuming the other call was more future
proof. I will dig into the code a bit.
> invalidateKeyCache / invalidateRowCache should remove saved cache files from
> disk

> the invalidate[Key|Row]Cache calls don't remove the saved caches from disk.
> It seems logical that if you are clearing the caches you don't expect them to
> be reinstantiated with the old values the next time C* starts.
> This is not a huge issue since next time the caches are saved the old values
> will be removed.
