In Pinot 1.0, we used to have a logic that the value of `STATE_TRANSITION.maxThreads` is set to 1 if this config is missing in the cluster. This will cause issue as this default value 1 will be used as the thread pool size, which will make Pinot cluster extremely slow. If you try to upgrade Pinot cluster from 1.0 to a higher version, please keep in mind that `STATE_TRANSITION.maxThreads` be set to a higher number instead of 1 in `CONFIGS/CLUSTER/pinot` Znode before rolling out to higher Pinot version. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
