Jamie Grier created FLINK-6199: ---------------------------------- Summary: Single outstanding Async I/O operation per key Key: FLINK-6199 URL: https://issues.apache.org/jira/browse/FLINK-6199 Project: Flink Issue Type: Improvement Components: DataStream API Reporter: Jamie Grier
I would like to propose we extend the Async I/O semantics a bit such that a user can guarantee a single outstanding async request per key. This would allow a user to order async requests per key while still achieving the throughput benefits of using Async I/O in the first place. This is essential for operations where stream order is important but we still need to use Async operations to interact with an external system in a performant way. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
