Hi devs, I'd like to initiate a discussion about FLIP-473: Introduce New SQL Operators Based on Asynchronous State APIs[1].
FLIP-424[2] has introduced an asynchronous state architecture to mitigate I/O bottlenecks in Flink by offloading state access to separate threads from the main thread in each task, thereby optimizing I/O and computational resource utilization. Building upon this infrastructure, FLIP-473[1] proposes introducing new SQL operators based on these asynchronous state APIs. Our goal is to enhance throughput and reduce latency in stateful operations by leveraging the new asynchronous state architecture in Flink SQL jobs. For more details, please refer to the FLIP-473[1]. Welcome any feedback and suggestions for improvement. There has been POC code[3] related to the Join operator. Best!
