Currently the new reversing sstable algorithms do not support fast forwarding and the cache does not yet handle reversed results. This forced us to disable the cache for reversed queries if we want to guarantee bounded memory. We introduce an option that does this automatically (without specifying `bypass cache` in the query) and turn it on by default. If the user decides that they prefer to keep the cache at the cost of fetching entire partitions into memory (which may be viable if their partitions are small) during reversed queries, the option can be turned off. It is live-updateable.
