Redis / KeyDB

This documentation is valid for both Redis as well as KeyDB and Valkey. Both Valkey and KeyDB are forks of Redis, but should work mostly in the same manner.

Configure Redis

Edit the Redis instance for Mbin: sudo nano /etc/redis/redis.conf:

# NETWORK
timeout 300
tcp-keepalive 300

# MEMORY MANAGEMENT
maxmemory 1gb
maxmemory-policy volatile-ttl

# LAZY FREEING
lazyfree-lazy-eviction yes
lazyfree-lazy-expire yes
lazyfree-lazy-server-del yes
replica-lazy-flush yes

Feel free to adjust the memory settings to your liking.

warning

Mbin (more specifically Symfony RedisTagAwareAdapter) only support noeviction and volatile-* settings for the maxmemory-policy Redis setting.

Multithreading

Configure multiple threads in Redis/Valkey by setting the following two lines:

# THREADED I/O
io-threads 4
io-threads-do-reads yes

However, when using KeyDB, you need to update the following line (io-threads doesn't exists in KeyDB):

# WORKER THREADS
server-threads 4

Redis as a cache

Optionally: If you are using this Redis instance only for Mbin as a cache, you can disable snapshots in Redis/Valkey/KeyDB. Which will no longer dump the database to disk and reduce the amount of disk space used as well the disk I/O.

First comment out existing "save lines" in the Redis/Valkey/KeyDB configuration file:

#save 900 1
#save 300 10
#save 60 10000

Then add the following line to disable snapshots fully:

save ""
