Hi everyone, Thanks all for joining the discussion in the doc[1]. It seems that the discussion is converged and there is a consensus on the current FLIP document. If there is no objection, I would like to convert it into cwiki FLIP page and start voting process.
For more details, please refer to the design doc (it is slightly changed since the initial proposal).
