Jingsong Lee commented on BEAM-2393:
------------------------------------
Now there is no relationship with Dynamic Work Rebalancing.
The main question is how to checkpoint to {{BoundedSource}}.
{{BoundedToUnboundedSourceAdapter}} gives a way: calling splitAtFraction or
snapshot all the rest of the elements.
[~iemejia] Can there be a simpler way for HBaseIOs to implement the
splitAtFraction method?
> BoundedSource is not fault-tolerant in FlinkRunner Streaming mode

> {{BoundedSourceWrapper}} does not implement snapshot() and restore(), when
> the failure to restart, it will send duplicate data.
