A quick script to set and get LZ4 compressed data from KeyDB or Redis.

compress.py

import lz4.frame
import redis
import sys

if (len(sys.argv) != 3):
    print("Usage: " + sys.argv[0] + " [set/get] [keyname]")
    print("\tFor GET data should be piped to stdin")
    sys.exit(1)

r = redis.Redis(host='localhost', port=6379, db=0)
if (sys.argv[1].lower() == "set"):
    data = sys.stdin.buffer.read()
    cdata = lz4.frame.compress(data)

    print("Original size: " + str(len(data)) + " compressed: " + str(len(cdata)))
    r.set(sys.argv[2], cdata)
elif (sys.argv[1].lower() == "get"):
    cdata = r.get(sys.argv[2])
    data = lz4.frame.decompress(cdata)
    sys.stdout.buffer.write(data)
