HI Daniel On Fri, Feb 17, 2012 at 1:44 PM, Daniel-Constantin Mierla &lt;miconda(a)gmail.com Yes, redis suppors LUA scripting through the EVAL command. Another possible approach would be to use pipelining. Instead of executing a query per prefix, redis offers has the feature of queing multiple commands and send them only once to the server. For example: redis 127.0.0.1:6379> multi OK redis 127.0.0.1:6379> "HGET" "tree:1000:routes" "3466157" QUEUED redis 127.0.0.1:6379> "HGET" "tree:1000:routes" "346615" QUEUED redis 127.0.0.1:6379> "HGET" "tree:1000:routes" "34661" QUEUED redis 127.0.0.1:6379> exec 1) (nil) 2) (nil) 3) "c=2000;q=100" That way the iteration could take place in the result having issued a single command. For that, the redis module should support both multivalue responses. I hadn't thought of using it, thanks for the tip. I will take a look.
