Redis behavior - Flush? Restart?

[Marco Ramos]

Hello everyone,

I set up a Redis server for my Canvas-LMS cluster.
It's running for 49 days without restart, keys flush, and problems.
My server has 16 GB of memory. In the beginning, Redis used 2 GB of memory, and now it's using almost 8 GB.
The Redis KeySpace info contains one DB (db0) with over 7.2 million keys; only 365 thousand will expire.

I'm wondering how do you deal with this kind of server.
Do you guys restart the server frequently? How often?
Do you guys run a flush command frequently? How often?

Best regards,
Marco.

Another information:

I was having problems with dumping the memory so I disabled this feature.

Because of this, I'll always lose the cached data when I restart the server.

check redis documentation

1. limit memory

redis-cli config set maxmemory 3gb

2. set key deletion policy

redis-cli set maxmemory-policy allkeys-lru

3. save and apply settings

redis-cli rewrite

Oh, nice.

I think it'll work.

I'll give it a try and let you know further.

Thank you.
