OS: RHEL 7.6
Cluster set up:
Single node - 6 instances of redis - 3 master and 3 slaves. 16384 slots shared between three masters.
Sample data:
smembers 201904138
1) "0"
2) "1"
3) "2"
4) "3"
5) "4"
Each set contains 5 ids. I have such 2.49Million keys.
Sample size occupied by each entry:
memory usage 201904138
(integer) 76
:7001> memory usage 201904132
(integer) 76
:7001> memory usage 201904134
(integer) 76
:7001> dbsize
(integer) 2489174
So logically it should occupy 2.49M * 76 = 189MB. I do understand that it stores some extra information as well.
But total memory occupied by this cluster is Memory = 367M, RSS=389M
Why it is double than the original data? how can i reduce it?
Please help.
