Howto implement stored procedures within Redis (-with enable_strict_lua)

example1.sh

# Step 0 -- create test data
redis-cli HSET :object:30343552:data foo bar

# Step 1 -- store sample function 'sampleFunction'
redis-cli SET :functions:sample1 "
  redis.call('SELECT', 0);
  local data = redis.call('HGETALL', ':object:' .. ARGV[1] .. ':data');
  return table.concat(data, '+');
"

# Step 2 -- create function loader
functionId=$( redis-cli SCRIPT LOAD "return loadstring(redis.call('get',':functions:' .. KEYS[1])) ()" )
echo $functionId
# -> 
# f7f45841b566126a895857bb2e87890ee94f11bc

# Step 3 -- test
redis-cli EVALSHA $functionId 1 sample1 30343552 
# -> 
# "foo+bar"
