Subtables, performance and resouces

Hi,   I know that subtables should be be used sparingly because each subtable is pinned to TMM instance that created subtable - so it's using RAM of this TMM - could create uneven RAM consumption...

Hi,

 

I just started to think about implementing splitting master subtable and then performing lookups. Probably there is quite easy way to resolve this but I am a bit stuck.

 

Let's say I am using second method and splitting my master subtable (storing session ids as keys) int 3. From my test it looks like I have no control in advance which crc value from three possible will be generated. So in the end I don't know in which master subtable given session id key will be created.

 

Am I right here?

 

If do I assume that it's necessary to iterate through all subtables until given key will be found. I can't see any other way to check in which of master subtables given sessionID was stored - or I am wrong?
