Hi Luke, Hope you are fine, back from holidays and consecutively to our discussion the 5th of august, I replied to your comments regarding the JmsIO auto-scaling proposal: https://docs.google.com/document/d/1LMPpMpn9DByQcyCdRrTMBa-8ltByO4aqNYY4D9h3m18/edit?usp=sharing
To sum up : * The number of initial split is not important for us (JmsIO creates one connection/consumer per split and we are ok with that), * What is important is that the runner allocates more or less workers depending on the backlog size, * We have added the getSplitBacklogBytes methos to the AutoScaler interface. I will proceed with the pull request then. Best regards.
