Hi Dev, I was wondering if there's any previous discussion regarding how to handle burst network I/O when deploying Flink applications with window operators.
We've recently see some significant network I/O degradation when trying to use sliding window to perform rolling aggregations. The pattern is very periodic: output connections get no traffic for a period of time until a burst at window boundaries (in our case every 5 minutes). We have drafted a doc <https://docs.google.com/document/d/1fEhbcRgxxX8zFYD_iMBG1DCbHmTcTRfRQFXelPhMFiY/edit?usp=sharing> on how we proposed to handle it to smooth the output traffic spikes. Please kindly take a look, any comments and suggestions are highly appreciated. -- Rong
