State of KeyDB #3544

Open azerbe opened 1 month ago

azerbe commented 1 month ago

I was running into https://github.com/Snapchat/KeyDB/issues/802 and had problems to debug the issue, as I was not able to start that specific version (alpine_x86_64_v6.3.4) manually and it crashed without any log-output or other debugging information. Downgrading to 6.3.3 worked.

I then inspected the state of the container images and even the latest release (v6.3.4) is older then a year. Is it documented why KeyDB was choosen as alternative for Redis? I understand the license implications and I am not too deeply invested into the topic, so I cant bring up alternatives, but I would still like to understand why KeyDB was choosen and if it is considered a stable part of this playbook.

If there is no clear answer, feel free to close this issue. It is primarily intended as a link to the above mentioned issue on the KeyDB repo.

There have been others (see https://github.com/mother-of-all-self-hosting/mash-playbook/issues/247) reporting that 6.3.4 does not run on some CPUs (missing some instructions). Downgrading to 6.3.3 resolves the issue.

KeyDB was chosen as a popular and fast alternative to Redis as the licensing change was happening. Later on, more options have appeared. If we were to choose now, we may have gone with Valkey. At some point, we may even switch to it. It will probably be closer to what Redis was doing and will be maintained better than KeyDB is.
