Redis size / memory usage

[SB]

Is there a way to shrink the size of memory Redis uses?

What is actually stored within here?

[SH]

It is used extensively for non-critical data, there are lot of small objects stored mainly used for caching, karma, all statistics or message-id delivery status tracking. Every object in redis should have expiration so technicaly it should not take more memory unless you are handling more traffic.

How many emails/day are you handling? How many accounts do you have? I've checked couple instances and none of them is that big. I will try to create some usefull script to meassure inner content.

Currently around 600 users and 75 domains

add redis statistics (ref #520)

→ <<cset 138ca1f21991>>

[SH]

In next version there will be "poste-redis-statistics" command. Right now you can try curl -s https://poste.io/poste-redis-statistics | docker exec -i mailserver bash - the part with PREFIXES is what will be interesting

Hi SH, Thank you for the information - this is what I get. Does this list just show a breakdown of what is stored within redis?

echo ""
echo "INFO ALL"
echo "--------------------------------"
echo "info all"|redis-cli

echo ""
echo "PREFIXES"
echo "--------------------------------"
echo ""

sum "MSGID-TXID pairs" "msgid-txid|*"
sum "Top statistics" "top|*"
sum "Karma" "karma|*"
sum "Bruteforce login stats" "bruteforce|*"
sum "Login stats" "stats|*"
sum "Delivery status" "status|*"
sum "Bad connections block" "bbc|*"
sum "Automatic guard stats" "guard|*"
sum "Manual guard stats" "guard-manual|*"
sum "Limit stats" "limit|*"
sum "AS" "as*"
sum "rcache" "rcache|*"

sum "fuzzy (rspamd)" "fuzzy*"
sum "BAYES (rspamd)" "BAYES*"
sum "RS (rspamd)" "RS*"
sum "1*" "1*"
sum "2*" "1*"

Is it possible to find out how much memory each is taking up?

[SH]

You are pasting unexecuted script. It needs to be executed inside container with $ curl -s https://poste.io/poste-redis-statistics | docker exec -i mailserver bash
