> Today Flink support various channels such as pipelined channel and blocking
> channel. Blocking channel indicate that data need to be persistent in a batch
> and then it can be consumed later, it also indicate that the downstream task
> cannot start to process data unless its producer finished and also downstream
> task will only depends on this intermediate partition instead of upstream
> tasks.
> By leverage this characteristic, Flink already support fine grain-failover
> which will build a failover region has reduce failover cost. However, we can
> leverage this characteristic even more. As described by this
> [paper|http://www.vldb.org/pvldb/vol11/p746-yin.pdf] (VLDB 2018), *_Bubble
> Execution_* not only use this characteristic to implement fine-grain
> failover, but also use this to balance the resource utilization and job
> performance. As shown in the paper (also in the following chart), with 50% of
> the resource, it get 25% (0.75 speedup) average slow down for TPCH benchmark.
