[DISCUSS] Proposal for Asynchronous I/O in FLINK

[David Wang]

Hi ALL,

Recently, we have designed and implemented a proposal in FLINK to
support Asynchronous
Operation while streaming. The main feature of this proposal is to
introduce async i/o operation in FLINK to boost the TPS of streaming
job without delaying the checkpoint, and provide an easy way for the FLINK
users to implement their async i/o codes in FLINK job.

Here is the link to Google Doc: https://docs.google.com/

Any feedback is appreciated.

Thanks,
David
