Hi,
Docs says
It is not necessary to free a reply to use it again in a new redis_cmd
function. When ndb_redis module closes, all pending replies are freed
automatically..
Question is when is ndb_redis module closed, if there are no active calls
it should be closed, shouldn't it?
I am using variable in each Lua function, even if they are global they
should be wiped off after call is finished?
I will see how to work collectgarbage("collect") as explained by Michael
Hajek in another email.
Thanks guys.
