Questions:
1. FLUSHALL deletes all the keys but memory used still remains same? How do I release memory used by flushed/purged/deleted keys?
2. I have a key with memory usage of 120 bytes. How much more memory is taken by the TTL of 3600 seconds for this key?
3. Do expired keys also not release memory? Or is it only deleted keys?
4. Premium P1 of 6GB with 1 Shard (2 nodes primary/replica) - Does this mean we have 3GB for read/writes and 3GB is replica? Is this configurable?
