i think need store separate count unique values. can length of single hash, not when in case got 3 different keys.

command key field value

hset 1000 state "ca"

hset 1000 zip "95054"

incr ca

hset 2000 state "ca"

hset 2000 zip "95050"

incr ca

hset 3000 state "ny"

hset 3000 zip "12345"

incr ny

if want how many hash keys state "ca" use:

get ca
