Redis / KeyDB

This documentation is valid for both Redis as well as KeyDB. KeyDB is a fork 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 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. 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 configuration file:

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

Then add the following line to disable snapshots fully:

save ""
