I am aware of redis-cli, and the info and config commands. However, they do not have anything that states the size of the current database. How could I figure this out?

You can check the actual number by running redis-cli config get databases. In interactive mode, the database number is displayed in the prompt within square braces. For example, 127.0. 0.1:6379[13] shows that the 13th database is in use.
The Redis configuration file is located at installdir/redis/etc/redis. conf.
There is no command to do it (like you would do it with MySQL for instance). The number of Redis databases is fixed, and set in the configuration file. By default, you have 16 databases. Each database is identified by a number (not a name).
Redis Key Memory Info You can use two main commands if you want to view the keys in a Redis datastore. Dbsize – The Redis dbsize command shows the total number of valid keys in a specific database. Info keyspace – This command shows the keys in each database available in the Redis cluster.
Using the INFO command. full details here: http://redis.io/commands/info
sample output:

After selection of db Use dbsize command to display the size of selected db.
Select 9 OK dbsize (integer) 20953296 for listing overall information of your redis type info and to view only memory just type
