--cache-backend-redis-compression-lib=l4z \

[magenx]

that combination lz4 vs l4z for session and cache compression was taken from magento 2 cli redis cache documentation and from https://github.com/colinmollenhour/Cm_Cache_Backend_Redis

you can see it like:

bin/magento setup:config:set --cache-backend-redis-compression-lib  --help | grep l4z
      --cache-backend-redis-compression-lib=CACHE-BACKEND-REDIS-COMPRESSION-LIB
Compression lib to use [snappy,lzf,l4z,zstd,gzip] (leave blank to determine automatically)
