   > One last high-level question (it's been a while since I reviewed the Pulsar connector): Unique IDs are not stable after failure as far as I can see, could we lose data after recovery somehow? Or are the IDs only used to distribute the load?
   
   This unique id is just like a naming for different produce/consumer instances on Pulsar. The correctness of data when producing and consuming depends on the Pulsar transaction.
