Append to list stored in table key

Hi,

First of all I wonder if this is good idea to store list in sub/table key - considering performance nad memory consummatum. Let's say it could be list containing no more that 10 IPs.

Second I wonder if there is faster more elegant way to actually add new value to the list. My idea is:

set c_val [table lookup -subtable ip [IP::client_addr]]

lappend c_val $new_val

table set -subtable ip [IP::client_addr] $c_val

Seems to be a lot overhead here, so maybe there is better way?

What will be the values new_val?

How will you use it?

Will these keys expire? (you do not have set timeout)

you may create one subtable per IP address and define one key per val...

table add -subtable ip-[IP::client_addr] $c_val 1 3600 foreach c_val [table keys -notouch -subtable ip-[IP::client_addr] ] { do what you want }
