How does one insert the loop parameters operator, and put the existing process inside this operator without losing all connections?

Best regards,

    I have exactly same question.. but for Loop Values operator

    Situation: I Loop over big number of values of specific attribute. On each iteration I get additional data from particular (always the same database) and produce calculation results. If it goes too fast Rapid Miner eventually can't open new connection to that database, all ports are in use... so, I have to introduce some kind of delay in order to grab new data from database.. I think, it would be more practical to save and re-use already opened connection... Question: how we can do it?

    I do have additional workaround for this problem: Use Remember operator and do filtering on each iteration step... but this involves more memory and time consumption - size of overall data is huge.

    Thank you for you comments and suggestions!
